BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to processes and compositions that meet at least one, preferably all, of the following objectives when applied to shaped metal surfaces, more particularly to aluminum surfaces and / or tinplate containers, either after cleaning or as part of cleaning: (i) reducing the coefficient of static friction of the treated surfaces after drying said surfaces, without adversely affecting the adherence of paints or lacquers applied thereto; (ii) stimulating the drainage of water from the treated surfaces, without causing 'water brea s')', that is to say activation of the drainage which results in a continuous film of water on the containers, instead of droplets separated by relatively dry areas called 'interruptions of the aqueous film' between the water droplets, and (iii) decreasing the temperature of the drying oven required to dry said surfaces after having been rinsed with water. Prior Art The following discussion and description of the invention will be based first on aluminum containers, since the members represent the field of greatest volume of application of the invention. However, it is understood that, without the obviously necessary modifications, both the discussion and the description of the invention are also applicable in steel vessels coated with tin and in other types of shaped metal surfaces, for which any of the objectives indicated is interesting in practice. Aluminum beats are commonly used as containers: for a wide variety of products. After their manufacture, aluminum cans are commonly washed with acidic cleaners to extract fine aluminum particles and other contaminants therefrom. Recent environmental considerations and the possibility that the residues remaining on the cans after the acid wash could have an influence on the flavor of the beverages packaged in the cans, has concentrated the interest in alkaline cleaning to extract such fine and polluting particles. However, the treatment of aluminum cans with alkaline or acidic cleaners generally results in different rates of pickling of the metal surfaces on their external part as compared to the internal part BU. For example, the optimal conditions required to achieve a surface free of fine aluminum particles in the inner part of the containers, generally produce problems of mobility of the cans on the conveyor belts., due to the greater roughness of the external surface of the can. Aluminum cans that lack a low coefficient of static friction (abbreviated 'COF') on the outer surface, generally do not overlap each other smoothly in the lines of travel of a packing plant. The release of the blockages resulting from faults in the normal flow is negative for the people who operate the plant and costly due to loss in production. The COF of the internal surface is also important when the cans are processed through most conventional decorating devices. The operation of these machines requires that the cans slide over a rotating mandrel which is then used to pass the cans to rotating cylinders which transfer decorative inks to the outer surface of said cans. A can that does not slide easily on or out of the chuck can not decorate properly and results in a production failure called 'print failure'. In addition to the badly charged can directly causing this printing failure, three to four cans are usually lost before and after the one that is poorly loaded or as a consequence of the mechanics of the printing and transport systems. The bottlenecks and printing failures have increased, since line speeds have increased in recent years to levels of between 1200 and 1500 cans per minute, a figure that is common today. As a consequence, the need has arisen in the industry of the manufacture of cans, particularly in the case of aluminum cans, to modify the COF on the external and internal surfaces of the cans to improve their mobility. An important consideration in modifying the surface properties of cans is the concern that such modification may interfere with or adversely affect the ability of the can to be decorated when it passes to a printing or labeling station. For example, after cleaning the cans, labels can be stamped on their outer surface, and lacquers can be sprayed on their inner surface. In this case, the adherence of paints and lacquers is an aspect of great interest. Accordingly, an object of the present invention is to improve mobility without adversely affecting the adherence of paints, decorative inks, lacquers or the like. In addition, the current trend in the can manufacturing industry is directed towards the use of thinner calibers of aluminum metal material. This decrease in the calibration of the metal material of the cans has caused a problem in the production since, after washing, the cans require a lower temperature of the drying oven to pass the pressure quality control test for column resistance.

However, the decrease in the drying oven temperature resulted in the cans not being sufficiently dry: they were dry when they arrived at the printing station, which caused ink blots on the label and a higher rejection rate. A means of decreasing the temperature of the drying oven would be to reduce the amount of water remaining on the surface of the cans after washing. Consequently, it is convenient to activate the drainage of the rinse water from the treated surfaces. However, in doing so it is important to avoid the formation of surfaces with interruptions of the aqueous film, as indicated above. These interruptions give rise to a perception, increasing the possibility in reality, of non-uniformity in practically important properties in various areas of the treated surfaces. Accordingly, it is desirable to provide a means of improving the mobility of the aluminum cans in single rows and through stamping devices to increase them. production, reduce bottlenecks in the production line, minimize downtime, reduce the deterioration of the cans, improve or at least not adversely affect the printing of ink and allow the reduction of the temperature of the drying oven of the cans washed.

In today's most widespread practice, at least for large-scale operations, aluminum cans are commonly subjected to a succession of six cleaning and rinsing operations, as described in Table I below. (Contact with mains water at room temperature before any of the stages in Table I is also used, when this is often called 'preliminary' to the numbered steps). Preferably, at least the operations described in Steps 1, 2, 3, and 6 of Table I are used in practice: stage 1 may be omitted, but the results are generally less satisfactory than when included.

It is now possible to produce a can that is satisfactorily mobile and in which the subsequently applied inks and lacquers have adequate adhesion using suitable surfactants, either in Stage 4 or Stage 6, as indicated above. Preferred treatments for use in Step 6 are described in the US patent (s) nro (s). 4944889 and 4859351, and some of those marketed by Parker Amchem Division of Henkel Corporation (abbreviated 'PA' below), under the name 'Mobility Enhancer ™ 40' (abbreviated 'ME-40 ™').

However, it has been discovered that many manufacturers are reluctant to use chemicals such as ME-40 ™ in Stage 6. In some cases, this reluctance is due to the presence of a carbon filter for the DI water system (Stage 6). normal), a filter that may be inadequate due to the adsorption of surface-conditioning and lubricant-forming additives, such as those of ME-40 ™; in other cases, it is due to reluctance to make the necessary processing changes when using ME-40. For those manufacturers that prefer not to incorporate any lubricant or surface conditioning material to the final stage of rinsing, but wish to achieve the advantages that can be obtained by such incorporations, alternative treatments have been developed for use in Stage 4 described above, those indicated in the US patent (s) nro (s). 5030323 and 5064500. Some of these materials are marketed by PA under the name of FIXODINE ™ 500.

However, the reduction in the coefficient of friction provided by previous art treatments, either in Step 4 or 5, can be substantially reduced, often to an unacceptable level, if the treated cans are subjected to an extraordinary heating after completing the six processing stages described above. Such extraordinary heating of the cans in the drying oven occurs when a high-speed production line is stopped for a few minutes., a fact that in practice is nothing strange. In practical terms, the higher COF measurements are interrelated with the loss of mobility, thus nullifying the purpose of introducing mobility enhancing surfactants in the can washing formulations. Accordingly, an object of the present invention is to provide means for improving the mobility of the aluminum cans and / or achieving one of the other objectives indicated above, which higher ion ** than that indicated in "1 prior art". , particularly with respect to the stability of the beneficial effects of heating well below the minimum necessary to dry treated surfaces. Also, some beverages packaged in aluminum cans can be pasteurized and, unless the temperature and compositions of the aqueous solution with which the cans come into contact during pasteurization are carefully co-cooked, staining can often occur. the top of the can during pasteurization. Another object of some embodiments of the invention is to provide compositions and methods suitable for use in reducing the coefficient of friction that also resists said staining of the upper part during pasteurization. Still another object of some embodiments of the present invention is to provide a combination of alkaline cleaner and mobility enhancer, so that incorporation of an improving ingredient is not required after Step 2 described above. In a particularly preferred embodiment, this is accomplished with cleaning ingredients that are substantially free of fluoride at any cleaning step. DESCRIPTION OF THE INVENTION In addition to the operative examples, or in other cases that are indicated, all the numbers that express quantities of ingredients or reaction conditions used herein are understood as modified in all cases by the term "approximately" to describe the greatest scope of the invention. However, practice is generally preferred within the indicated numerical limits. Also, unless otherwise stated, the description below of groups of chemical materials, indicated as suitable or preferred for a specific ingredient according to the invention, implies that mixtures of two or more of the members of the individual group are suitable or preferred. at level 1 that the group members used alone. In addition, the specification of chemical materials in ionic form should be understood as implying the presence of some necessary counterions for the electrical neutrality of the total composition. In general, said counterions should be first selected, as far as possible, from the ionic matters specified as part of the invention.; any remaining contraction that is needed can generally be freely selected, with the exception of any counterion that affects the objectives of the present invention. SUMMARY OF THE INVENTION In accordance with the present invention, it has been found that a lubricant and a surface conditioner applied to aluminum can * d ** puéa of the wash to * joran * u mobility and, in a preferred embodiment, improve its drainage characteristics of aqueous film and evaporation to allow to decrease the temperature of a drying oven between approximately 25 ° C and 38 ° C, without adverse effect on the labeling process. The lubricant and surface conditioner reduce the coefficient of static friction on the external surface of the cans, allowing a substantial increase in the speeds of production lines, also providing a marked improvement in the speed of drainage and evaporation, resulting in a savings in energy demand, while meeting the requirements of quality control. Various embodiments of the invention include a concentrated lubricant and a surface conditioner forming composition as set forth above, a solution of said composition in water, optionally with acid or base! additional to adjust the pH value, such as the complete composition suitable for contacting a metal surface, in Step 2, Step 4, and / or Step 6 of a six step cleaning and rinsing process as indicated above , and processes that include contacting a metal surface, particularly an aluminum surface, with an aqueous composition that includes the ingredients of any lubricant and surface conditioner forming composition specified in detail above. BRIEF DESCRIPTION OF THE DRAWINGS FIGS. 1 (a) - 1 (d) illustrate the effect that fluoride activity has during the cleaning of cans prior to applying a lubricant and a surface conditioner according to the invention on the characteristics of the cans after of the processing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS More particularly, according to a preferred embodiment of the present invention, it has been discovered that the application of a thin organic film to the outer surface of aluminum cans can serve as a lubricant, inducing a lower static coefficient of friction, which produces, er. consequently, improved mobility for the cans, also increasing the speed at which the cans can dry and passing the pressure quality control test for the column resistance. It has also been found that the degree of improved mobility and speed of drying of the cans depends on the thickness or proportion of the organic film and on the chemical nature of the material applied to the cans. The lubricant and surface conditioner for aluminum cans according to the present invention can, for example, be selected from water-soluble alkoxylated surfactants such as organic phosphate esters, alcohols, fatty acids including mono-, di-, tri- and poly-acids, fatty acid derivatives such as salts, hydroxy acids, amides, esters, particularly alkylesters of 2-substituted alkoxylated fatty alkyloxylated acetic acids (briefly referred to below as 'oxa-acid esters'), described in greater detail in the Patent Application American No. 843135, filed on February 28, 1992, ethers, derivatives and mixtures thereof. The lubricant and surface conditioner for aluminum cans according to the present invention in one embodiment preferably comprises a water-soluble derivative of a saturated fatty acid, such as an ethoxylated stearic acid or an ethoxylated isostearic acid, or alkali metal salts thereof, such as polyoxyethylated stearate and polyoxyethylated isostearate. Alternatively, the lubricant and surface conditioner for aluminum cans can comprise a water soluble alcohol with at least about 4 carbon atoms and can contain up to about 50 moles of ethylene oxide. Se: excellent results have been obtained when the alcohol comprises polyoxyethylated oleyl alcohol containing an average of about 20 moles of ethylene oxide per mole of alcohol. In another preferred aspect of the present invention, the organic material used to form a film on an aluminum can after alkaline or acid cleaning and before the last drying of the outer surface before being transported, comprises a water-soluble organic material. selected from a phosphate ester, an alcohol, fatty acids including mono-, di-, tri- and poly-acids, fatty acid derivatives including salts, hydroxy acids, amides, alcohols, esters, ethers and derivatives thereof and mixtures thereof .

A combination of fluoride ions with amine oxide or quaternary ammonium salts as described above, preferably the latter, is an important part of an especially preferred embodiment of the invention when good resistance of friction reduction to overheating and / or resistance to staining of the upper part during pasteurization. More particularly, a suitable additive for satisfying these objectives comprises, preferably: (A) a component selected from the group consisting of quaternary ammonium salt and amine oxide surfactant corresponding to formula I: wherein R1 is a monovalent aliphatic portion, which may B & T saturated or unsaturated and contains between 8 and 22 carbon atoms, or preferably between 12 and 18 carbon atoms, preferably arranged in a straight chain, each Rs and R3 is a monovalent portion independently selected from the group consisting of (i) alkyl and hydroxyalkyl portions having between 1 and 8, preferably between 1 and 4, more preferably 1 or 2, carbon atoms and (ii) aryl and arylalkyl portions with between 6 and 10 , or preferably between 6 and 8, carbon atoms,. R4 is a monovalent portion selected from the same group as for R2 and R3 plus the -O "portion; X" is a monovalent anion or monovalent fraction of an anion with a valence greater than 1; and a = 0 if R4 is -O ", and a = 1 if R4 is not -O"; (B) a component of a fluoride anion complex, with anions selected from the group consisting of fluotitanate, fluohaphnate and fluozirconate, preferred, and fluozirconate alone, highly preferred, and, optionally but preferably: (C) a component selected from the group formed by phosphite, sulfate and nitrate ions, with phosphate or a mixture of phosphate, is preferred with one of nitrate and sulfate or both, and, optionally, (D) aluminate anions, including fluoroaluminate anions and, optionally, (E) aluminum cations, including complex fluoroaluminum cations and, optionally, one or both of (F) a water-soluble and / or water-dispersible polymer that includes vinyl phenol-substituted portions, as described in detail in one or more of the US patent (s) nro (s). 5116912, 5068299, 5063089, 4944812, 4517028, 4457790, 4433015 and 4376000, and (G) a foam reducing component (antifoam). For the component (A) defined above, quaternary salts are preferred over amine oxides when resistance to spotting of the top is desired. Independently, it is preferred that at least two, or more preferably the three portions, R2, R3 and R4, are hydroxyalkyl groups, most preferably 2-hydroxyethyl groups.

For reasons of economy and commercial availability, it is preferred that the R1 portions in the materials used for the component (A) are mixtures of alkyl groups corresponding to the mixture of alkyl groups present in the fatty acid mixtures derived from hydrolysis of fats and natural oils , such as coconut oil, palm seed oil, animal tallow, etc. Alkyl tallow animal groups are particularly preferred. For component (B), fluozirconate ions incorporated as fluozirconic acid are highly preferred. The optimum amount of fluoride can be conveniently controlled during use, if desired, by means of a fluoride sensitive electrode, as described in US Patent (s) No .3431182, and marketed by Orion Instruments. . The 'fluoride activity', as this term is used in this case, was measured in relation to a 12OE Activity Standard Solution, marketed by PA, by a procedure described in detail in the PA Teshnical Process Bulletin (Technical Process Bulletin) No. 968. The Orion Fluoride Ion Electrode (Orion fluoride ion electrode) and the reference electrode provided with the Orion instrument are both immersed in the Standard Solution (standard solution) and the meter reading in millivolts is set at 0 with a Standard Knob (knob) er. the instrument, after waiting, if necessary, for any initial displacement in the readings to stabilize. The electrodes are then rinsed with deionized or distilled water, dried and immersed in the sample to be measured, which must be brought to the same temperature as the Standard Solution had when it was used to set the meter reading to 0. The reading of the electrodes submerged in the sample is taken directly from the meter in millivol-s (abbreviated later co or 'mv') of the instrument. With this instrument, lower mv positive readings indicate higher fluoride activity and mv negative readings indicate a fluoride activity still higher than any positive reading, with negative readings of high absolute value indicating an elevated fluoride activity. The initial reading of millivolts of a freshly prepared working composition that works well according to this embodiment of the invention should be maintained approximately, at least throughout the use of the composition. The cemv reading of free fluoride activity in said working composition according to this embodiment of the invention, including components (A), (B) and (C), as indicated above, should preferably be found preferably. "recent in the given order, within the range of between -30 and -120, -50 and -100, -60 and -85, -68 and -80, or -68 and -72, mv.

The anions specified for the component (C) indicated above are preferably incorporated into the mixtures according to the invention in the form of the corresponding acids. When resistance to staining of the upper part is desired, the component (C) preferably includes phosphate anions. Due to the preferred values for pH and for the ratio of the phosphate content of component (C) to components (A) and (B) when component (C) includes phosphate, which are considered below, usually some other Acid apart from phosphoric acid is required to maintain the pH within the preferred ranges, without exceeding the preferred phosphate ratio with respect to the other components. In such cases, nitric acid is preferably used when resistance to spotting is desired; the upper part; otherwise, any other acid strong enough and not interfering with the objects of the invention may be used; in such cases:, sulfuric acid is usually preferred in the first place, because it is less expensive than other strong acids. Components (D) and (E) are not normally incorporated into the composition of step 4 (except for test purposes), but usually accumulate in it as it is used under practical conditions for surface treatment aluminum. While aluminum is unlikely to have any beneficial effect, experience indicates that a normal equilibrium concentration in the commercial aluminum can cleaning lines will be within 100-300 parts per million by weight (abbreviated further 'ppm' ), satisfactory results can be obtained with compositions that include this proportion, or even more, of aluminum. Preferably, the total concentration of the components (D) and (E) is, preferably increasing in the given order, of not more than 1000, 700, 500, 450, 400, 370, 340, 325 or 315 ppm. In a complete Step 4 working composition, according to the embodiments of the invention including salts of amine oxide or quaternary ammonium as a necessary component, the pH is preferably maintained within the range of 2.3-3.3, more preferably between 2.5 and 3.1, even more preferably between 2.70 and 2.90. Lower pH values than those usually indicated, result in lower resistance than desirable for top spotting, while higher than indicated pH values tend to result in an inadequate pickling of the surface to ensure good adhesion of lacquers and / or inks subsequently applied. The incorporation of acid during prolonged operation is generally required to maintain these pH values, because the acidity is consumed by the process that forms the coating of lubricant and surface conditioner. If the surfaces being treated are predominantly aluminum, as is more common, it is preferable to include in the replacement acid, which is incorporated during prolonged use of the lubricant and the surface-forming composition, a sufficient amount of hydrofluoric acid to create a complex of the aluminum dissolved in the lubricant and in the surface conditioner forming composition during use. When the component (C) includes phosphate ions, as is generally preferred, the molar ratio between the components (Cp): (B): (A), where 'Cp' indicates the phosphate content of the component only (C) ) as indicated above, is, with increasing preference in the given order, of 1.0: (0.5-4.0): (0.25 - 8.0), 1.0: (0.5 - 2.0): (0.5 -6.0), 1.0: (0.7 - 1.3) :( 0.8 - 1.5), 1.0: (0.8 - 1.2) :( 0.90 - 1.40), 1.0: (0.90 • 1.10): (1.05 - 1.25), 1.0: (0.95 - 1.05): (1.05 - 1.15). If the component (C) is not used or does not contain phosphate, the ratio of (B): (A) with respect to these two components, falls preferably within the same ranges indicated above for cases where phosphate is included in the The compositions. Independently, the concentration of component (A) in a working composition of Step 4 is, preferably increasing in the given order, between 0.14 and 2.25, 0.42 and 1.50, 0.56 and 1.12, 0.67 and 0.98, or 0.77 and 0.88. , millimoles per liter (later abbreviated 'mM'); the concentration of the component (B) in a working composition of Step 4 is preferably between 0.20 and 2.0, or more preferably between 0.40 and 1.0 M, and the concentration of the component (Cp) in a working composition of Step 4 is, preferably, between 0.20 and 2.0, more preferably between 0.40 and 1.0, or even more preferably between 0.60 and 0.84 mM.

[In these numerical specifications, for the component (Cp), the stoichiometric equivalent as phosphate ion of any non-ionized phosphoric acid or anions produced by any degree of ionization of phosphoric acid is considered as phosphate anions]. Higher concentrations of the component (A) within the indicated amplitudes improve the resistance to staining of the upper part during pasteurization, but also increase the tendency of the composition to foaming and must be avoided for that reason. The lower the concentration of the component (A), the higher the concentration of the component (Cp) must be within the indicated ranges, when the resistance to staining of the upper part is important, because the component (Cp) seems to act synergistically with the component (A) to cause resistance to spotting of the upper part. Higher concentrations of component (B) are preferred within the ranges indicated when the concentration of components (D) and / or (E) is relatively high.

Under the same operating conditions, it is preferred that the compositions according to the invention including amine oxides and / or quaternary ammonium salts do not contain certain materials that are useful for the increase of mobility, even in other embodiments of the invention, and that they also do not contain other materials with various inconvenient properties.

A thin film with a coefficient of static friction is produced which is not more than 1.5 and is preferably smaller than the coefficient without said film, thus improving the mobility of the can when transported at high speed, without interfering with the lacquering, painted, stamping, or with other similar decoration processes later. The technique of incorporating said inorganic materials is described, particularly with reference to the zirconium-containing materials, in the US patent (s) nro (s). 503C323 of July 9, 1991 and 5064500 of November 12, 1991, which are incorporated as references. The substitution of other metallic materials instead of those specifically indicated in one of these patents is within the scope of those skilled in the art. In another preferred embodiment of the process of the present invention, to provide improved aqueous solubility, especially for the non-ethoxylated organic matters heredescribed and to produce a suitable film on the surface of the can with a coefficient of friction Static no more than 1.5 after drying, is used a mixture of one or more surfactants, preferably alkoxylate? and very preferably ethoxylated, together with said non-ethoxylated organic ateiria, to contact the surface of the clean can before final drying and transport.

In addition, the lubricant and surface conditioner for aluminum cans "according to the present invention may comprise an acid phosphate ester or preferably an ethoxylated alkyl alcohol phosphate ester. Said phosphate esters are marketed under the tradename Rhcdatac ™ PE 510 by Rhone-Poulenc Corporation, Wayne, NJ, and co or Ethfac ™ 136 and Eth € ae * 161 by Ethox Chemicals, Inc .. Greenville, SC. In general, the organic phosphate esters can comprise alkyl phosphate esters and contain them with and without ethoxylation. The lubricant and surface conditioner for aluminum cans can be applied to the cans during their washing cycle, during one of their cycles of treatment, such as cleaning or coating by conversion, during one of their cycles.Water-based rinse, or more preferably (unless the lubricant and surface conditioner includes a metallic cation, such as dessyrrhite), during its final AGUOSO cycle. In addition, the lubricant and surface conditioner can be applied to the cans after their final aqueous rinse, that is, before soaking in sickle, or after drying in the oven. through the application of uzxa fine water nebula or other non-flammable solvent solution. It has been found that the lubricant and surface conditioner is capable of being deposited on the aluminum surface of the cans to provide them with the desired characteristics. The lubricant and surface conditioner can be applied by spraying and reacting with the aluminum surface through chemoacsorption or physioadsorption, to provide the desired film. The contact method and the time between the: > € aqueous treatment compositions metal substrates to be treated, so also the temperature of the components, ee during the treatment, are in general non-critical characteristics of the invention; They can be taken from the previous known art. However, for large-scale operations, pressure spraying is the preferred singlet method, and contact times in stage 4 between 5 and 60 seconds (sec.), Or more preferably between 10 and 30 sec., and a temperature between 20 and 60 ° C, more preferably between 30 and 8 ° C. Generally, in the process of cleaning the cans, after they have been washed, they are commonly exposed to an acidic water rinse. According to the invention, the cans can then be treated with a surface lubricant and conditioner comprising an anionic surfactant tajl as an acid phosphate ester, The pH of the treatment composition is important and should be, in general, adido, ie between about 1 and 6.5, preferably between about 2.5 and 5. If the cans are not treated with the lubricant and surface conditioner of the invention after the acidic water rinse, they are often put in a rinse with network water and then to ux. Aqueous rinse deeionized. In this case, the deionized aqueous rinse solution is prepared to contain the lubricant and surface conditioner of the present invention, which may comprise a nonionic surfactant separated from the aforementioned polyoxyethylated alcohols or polyoxyethylated fatty acids, or any other material proper described. After said treatment, the cans can be passed to a kiln to dry before proceeding with the process. The amount of lubricant and surface conditioner remaining on the treated surface after drying should be sufficient to result in a COF value of not more than 1.5, or with increasing preference in the given order, of a value of not more than 1.2. , 1.0, 0.80, 0.72, 0.66, 0.60, 0.55 or 0.50. In general, said amount should be in the order of between 3 mg / m2 and 60 mg / m2 of lubricant and surface conditioner on the external surface of the cans. For reasons of economy, it is generally preferred that the aqueous lubricant and the surface-conditioning forming composition contain, preferably increasing in the order given, no more than 2.0, 1.0, 0.8, 0.6, 0.4, 0.30, 3.20 g per liter ( abbreviated 'g / L') of the organic matters necessary to form the lubricant and surface conditioning film on the treated surface after drying. Embodiments of the Invention with Desirable Special Characteristics Resistance to Growing Friction by Overstimulating Containers and Ties According to a particular preferred embodiment of the present invention, it has been found that the coefficient of friction of a treated surface, after the initial cleaning of the surface with a lubricant and surface conditioner is less easily damaged by heating when the lubricant and surface-setting composition includes at least one of the following organic matters: alkoxylated or non-alkylated castor oil triglycerides and derivatives of hydrogenated castor oil; alkoxylated and non-alkoxylated amine salts of a fatty acid including mono-, di-, tri- and poly-acids; alkoxylated and non-alkoxylated amino fatty acids; Non-alkoxylated and non-alkylated fatty amine N-oxides, alkoxylated and non-alkoxylated quaternary ammonium alkyls, 2-eubstituted alkyloxylated alkyloxy fatty acid esters (briefly denoted as 'acid oxa-esters'), as described in more detail in U.S. Patent Application No. 843135, filed on February 28, 1992, which is incorporated by reference, and water-soluble alkoxylated and non-alkoxylated polymers. Furthermore, if. The lubricant and surface conditioner is not applied to the surface of the last aqueous composition with which it is brought into contact with the surface before its last drying and before the automated transport. ~ <; the composition including the organic matters also preferably includes a metallize element selected from the group consisting of zirconium, titanium, cerium, aluminum, iron, tin, vanadium, tantalum, niobium, molubdene, tungsten and hafnium in metallic or ionic form, and the film formed on the surface as part of the lubricant and surface conditioner in dry form must include some of this metal element - along with organic matter. Friction Reduction Treatment as a Part of Initial Cleaning When the last contact of the treated metal surfaces with suitable materials to form a layer of lubricant and surface conditioner on them is produced in Step 2, as indicated above, many of the preferences indicated above need to be modified in part, as indicated below. A particularly obvious deviation in part of current commercial practice is that if mobility enhancing materials are incorporated into a Stage 2 cleaner, said cleaner should be alkaline. More specifically, the pH of the composition is, preferably increasing in the order given, of at least 11.0, 11.2, 11.4, 11.5, 11.6, 11.7, 11.8. 11.9 or 12.0 and independently is, with increasing preference in the given order, of no more than 12.5, 12.4, 12. "j, 12.2, or 12.1 In general, the pH values within this range produce a better internal brightness and external appearance, but lower pH values within this range produce surfaces treated with lower COF values and consequently better mobility, because mobility is adequate for most objectives, even at the higher end of the range, a pH value between 12.0 and 12.1 is generally the most preferred.The contact time may vary within wide limits, but in general it is, with increasing preference in the given order of at least 3, 8, 15, 25 38, 46, 54 or 57 seconds and independently, with increasing preference in the given order, of not more than 300, 150, 100, 83, 75, 68 or 63 sec.The temperature during the contact can also be varied within broad limits, but in general, it is preferred in the increasing order of at least 20, 25, 30, 34, 37, 40, 42 or 44 ° C, and independently, with increasing preference in the given order, of not more than 95, 85, 75, 66, 61, 57 or 54 ° C. The contact method is also not critical, but spraying is generally preferred. In addition to the alkalinity agent to achieve the above-mentioned pH levels, an alkaline cleaning composition wherein an improving lubricant and a film-forming surface conditioning material are preferably included, contains (i) a component of complexing agent present in an effective ratio to create complexes of at least some of the metal ions in the operating bath, which tends to form insoluble precipitates, and (ii) one or a combination of selected eurfactants in a sufficient proportion for (ii.l) extract the organic dirt present in the substrate being cleaned, (ii.2) prevent an accumulation of said organic dirt in the cleaning solution, (ii.3) avoid redeposition of organic dirt on clean cans, and / or (ii) .4) inhibit white spotting by pickling. The composition may optionally contain a foam suppressant agent of any of the types conventionally employed in other similar alkaline cleaning solutions, depending on the types of surfactants used in the cleaning composition and the manner in which the aqueous cleaning composition is applies to the substrate, to minimize the sirable foaming of the same. A convenient filling or replenishment of the cleaning composition can be performed using a dry powder concentrate of the active constituents or, alternatively, an aqueous solution or concentrated aqueous suspension, facilitating incorporation and mixing with the cleaning composition of the product during use. The alkalinity agent may comprise one or a combination of compo compatible and soluble in the bath including borate, carbonates, hydroxides or phosphates of alkali metals or alkaline earth metals, as well as mixtures thereof, constituting the hydroxides of alkali metals and carbonates of alkali metals the preferred materials, with sodium hydroxide being particularly preferred. The alkalinity agent is preferably prepared and maintained in the bath at an effective concentration to remove substantially all of the fine aluminum particles on the surfaces of the containers, while not ly removing the aluminum surface, providing a clean, bright and reflective; said efficiency is normally achieved when the pH values of the operating bath are maintained within the ranges indicated above. Normally, to achieve a pH value within the desired range, the alkalinity agent or combinations thereof are employed in a concentration of between 0.05 to 10 g / L, usually with concentrations of between 0.4 and 3.5 g / L being preferred, since they will normally give a pH value within one of the most preferred ranges. The complexing agent may comprise any or a combination of compatible and soluble compounds that are effective to create a complex of at least some of the metal ions present in the bath 4? operative to avoid the formation of harmful precipitates. Ge include among these complexing agents, suitable for use in the alkaline cleaner of the present invention, glusonic acid, citric acid, glucoheptanoic acid, sodium tripolyphosphate, tetraacetic acid of ethylenediamine IEDTA), tartaric acid or the like, so also the eales and soluble and compatible mixtures thereof. Preferably, the complex producing agents are selected from molecules that conform to one of the following general formulas: Q- (CHOH) .- Q 'and MOOC- tCH2C (OH) (COOM')] b-COOM "", where each Q and 0, which may be the same or different, represents CH20H or C00M; each M, M 'and M "', which may be the same or different, represents hydrogen or an alkali metal cation, a is an integer with a value of at least 2 and preferably not more than 6, more preferably no more than 5, and b is an integer with a value of at least 1, preferably not more than 3. Generally, the concentration of the complex-creating agent in the operating bath is, preferably increasing in the given order of not less than 0.2. , 0.4, 0. "', 1.0, 1.3, 1.6, 1.9, 2.1, 2 3, 2.5, 2.7, 2.9, 3.1. 3.3, 3.4, 3.5, 3.6, 3.7 or 3.8 millimoles per liter (mM) and independently, with increasing preference in the given order, of no more than 50, 35, 2C, 15, 10, a .. 7, 6.5, 6.0 , 5-7, 5.4, 5.2, 5.0, or 4.9 mM.

A preferred tertiary ingredient or alkaline cleaning solution is a cleansing component that has a Hydrophilic-Lipophilic Balance (HLB), that is, the balance of size and resistance of hydrophilic groups (affinity with water - polar) and lipophilic (affinity with non-polar oils) of the molecule, in a range of between 12 and 15. (For information on the determination of the number of HLBs of surfactants and emulsifying agents, refer to Chapter 7, pages 18 and 19 of a publication entitled 'The Atlas HLB System', 3rd edition, 1363, from Atlas Chemical Industries, Inc.). A HLB number of at least 12 is generally preferred to achieve efficient removal of lubricants and organic soils of the types usually employed in the drawing and pressing of aluminum containers, with relatively low surfactant concentrations, while inhibiting stains. white pickling If the surfactant has a HLB number greater than 15, increased amounts of surfactant are generally needed to achieve a satisfactory cleaning of the body of the container and to prevent undesirable accumulation, in the aqueous alkaline cleaning composition, of the concentration of organic soils, that tend to redeposited on the surfaces of the container. Even more preferred is an HLB value of at least 13.

Commercial surfactants which have proved particularly satisfactory for cleaning according to the present invention include Targitol ™ 15-3-9 which, it is reported, comprises an ethoxylated secondary alcohol (with an HLB value of about 13.5), marketed by Union Carbide Corporation ,; Neodol ™ 91-8, which is reported to comprise an ethoxylated linear alcohol (with an HLB value of about 14.1), marketed by Shell Chemical Company; Igepal ™ CO-630, which is reported to comprise an ethoxylated alkyl nonylphenol (with an HLB value of about 13.0), marketed by Rhdne-Poulenc; and Triton ™ N-101, which is reported to have the same general chemical description indicated for Igepal ™ CO-630, but with a slightly lower degree of etchilation and an HLB value of 13.1, and marketed by Union Carbide Corp. Additional cleaning surfactants suitable for use in the practice of the present invention include, for example, those having hydrophobic groups comprising alkylphenales, linear alcoholes, branched chain alcohols, secondary alcohols, propylene oxide / propylene glycol condensates or the like and groups hydrophilic such as ethylene oxide, ethylene oxide / ethylene glycol or eimilar ethylene esters, which may also contain closure groups such as propylene oxide, chloride, benzyl chloride, amines or the like.

The surfing days of the above-mentioned cleaning types can also be represented by the following structural formula F. (OR ') nOfí, where R is a portion of monovalent hydrocarbon containing between 6 and 30 carbon atoms, R' is a group aiquileno c propileno, and n is an integer with a value of ertre 5 and 100, The active hydrogen at the end of this structural formula can be replaced using conventional closure groups according to known techniques.

Preferably, the cleaning surfactant component is used in a concentration that is, preferably increasing in the given order, of at least 0.01, 0.05, 0.10, 0.20, 0.30, 0.35, 0.39, 0.42, 0.44, 0.46, 0.47, 0.48. , 0.48, or 0.5D g / L e, independently, it is not more than 50, 25, 15, 10, 5, 4, 3, 2.5, 2.0, 1.7, 1.5, 1.4, 1.3, 1.2, 1.1 or 1.0 g / L. The lubricant and surface conditioner forming component, alternatively called 'mobility enhancer', in a primary alkaline cleaning composition, is preferably chosen from the group consisting of quaternary ammonium salts and ethoxylated phosphate esters, as described above. Quaternary ammonium salts are more preferred when it is desired to minimize interruptions of the aqueous film, as is generally the case, the lubricant and surface-forming quaternary ammonium salts particularly preferred are those having (i) a long alkyl or alkenyl moiety. , preferably a straight chain portion with between 1C and 22, more preferably between 12 and 18, carbon atoms, attached to a quaternary nitrogen atom in each molecule, (ii) at least two, more preferably at least three , hydroxyalkyl portions with between 2 and 4, puy preferably two, carbon atoms in each of said hydroxyalkyl portions also linked to each quaternary nitrogen atom; and (iii) alkyl or alkenyl portions, optionally substituted aryl or including a quaternary ammonium group or both, with 1 to 8 carbon atoms, not counting those in any other substituent of any quaternary ammonium group present in the alkyl group or alkenyl; each one of estae. chemical characteristics (i) - (iii) indicated are preferred both individually and jointly. To shape within a reasonable contact time a quantity of lubricant layer and surface conditioner that adequately reduces surface friction, it is preferred that an alkaline cleaner, with a mobility enhancer also, contain at least 0.05, 0.12, 0.25, 0.46, 0.60, 0.75, 0.87, 1.00, 1.12, or 1.22 g / L of the mobility enhancer. Independently, in order to avoid excessive cost, it is increasingly preferred in the given order, that the concentration of the mobility enhancer in an alkaline working cleaner does not exceed 12, 5, 3.5, 2.7, 2.3, 2.1, 1.9, 1.82, 1.74, 1.67, 1.60, or 1.53 g / L. (In a concentrated composition, intended for dilution with water before its actual use for cleaning, the optimum concentrations would, of course, be greater than these). Depending on the particular type of surfactant or surfactants used, the manner in which the cleaning solution is applied to the aluminum containers and the concentration and processing parameters, it is further contemplated that an antifoam agent may also be incorporated into the cleaning composition to avoid eputation. objectionable. Any of a variety of antifoam agents that are marketed can be used for that purpose; it has been found that microcrystalline wax based agents are particularly satisfactory. It is also known that it is desirable to subsequently rinse a surface that has been cleaned with alkaline agents with a neutral or acidulous aqueous rinse solution with a controlled pH to extract the residual cleaning solution from said surface. Discoloration with brown oxide of clean aluminum containers that could occur during or shortly after the aqueous rinse of the same after the primary alkaline cleaning stage, it can be substantially eliminated by employing an aqueous rinse in which the pH remains substantially neutral or acidic. Due to the dragging of the aqueous alkaline cleaning solution to the next rinse step, said rinse becomes generally more alkaline, and the absence of preventive measures. To avoid any accumulation of alkalinity in the subsequent rinsing stages, it has been discovered that it is convenient to overflow the rinsing and / or neutralization of any alkaline accumulation with the incorporation of acid, to maintain the pH of the rinsing solution at a level preferably less than about pH 7.5, more preferably of pH 7 or less. By maintaining the subsequent aqueous rinse solutions at an almost neutral or acidic pH, the formation of brown spots on the bodies of the aluminum containers is substantially eliminated, even when there are arrests of the line in the rinsing stage. In many operating conditions, it is desirable to use fluorine in any chemical form to avoid environmental pollution at minimal cost. The alkaline cleaning processes described above are suitable for this purpose, frequently preferring that any aqueous composition used in said process, independently for each composition, as well as all of them together, must contain, preferably increasing in the order given, no more than 1.0, 0.5, 0.3, 0.2, 0.15, 0.10, 0.07, 0.04, 0.02, 0.01, OR.005, or 0.001 g / L of fluorine in any chemical form. For a more complete appreciation of the invention, we can refer to the following examples, which are intended to be merely descriptive, illustrative and not limiting as regards the scope of the invention, with the exception of those incorporated in the appended claims. Example of Group 1 This example illustrates the necessary amount of lubricant and surface conditioner for aluminum containers to improve the mobility of the cans through the printing lines and stations, also indicating that the lubricant and euphoric conditioner have no adverse effects on the adhesion of the printed labels on the external surface, as well as on the sprayed lacquers on the inner surface of the cans. Uncleaned aluminum cans obtained from an industrial manufacturer were washed clean with an alkaline cleaner marketed by PA, using the company's Ridoline ™ 3060/306 process. The cans were washed in a rotating washing machine (abbreviated 'CCW), which processes 14 cans at a time. The cans were treated with different amounts of lubricant and surface conditioner in the final rinse stage of the CCW and then dried in an oven. The surface lubricant and conditioner comprised approximately 10% active concentrate polyoxyethylistearate, or an ethoxylated nonionic surfactant, marketed under the tradename Ethox ™ MI-14 by Ethox Chemicals, Inc.

Greenville, SC. Treated cans were returned to the manufacturer for line speed and stamping quality evaluations. The printed cans were divided into two grubos, each formed by between 4 and 6 cans. All were subjected to one of the following test solutions for adhesion for 20 minutes: Solution | ie Test A. 1% Joy ™ solution (a commercial liquid dishwashing detergent, from Procter &Gamble Co.) in 3: 1 deionized water at a temperature of 82 ° C. Test solution B: 1% Joy ™ detergent solution in water at a temperature of 100 ° C. After removing the printed cans from the test sample, each lac was scratched using a sharp metal object to expose aluminum lines through the paint or lacquer, and was tested to determine the adhesion of the paint. This test included the Scotch ™ No. 610 Scotch ™ transparent tape firmly on the scratched area and then pulled the tape back against itself with a fast pulling motion,? such that the tape is. detached from the scratched area. The results of the test were classified as follows: 30, perfect, when the tape did not peel off any surface paint; 8- acceptable, and 0 total failure. The cans were subjected to a visual examination to determine if there were signs of peeling of the printing lacquer. In addition, the cans were evaluated for their coefficient of static friction using a laboratory static friction tester. This device measures the static friction linked to the surface characteristics of aluminum cans. This is done using a ramp that rises in a 90 ° arc using a constant speed motor, a reel and a cable attached to the free oscillating end of the ramp. A support fixed to the bottom of the ramp is used to hold 2 cans in a horizontal position approximately 1.3 cm apart, with their upper parts oriented towards the fixed end of the ramp. A third can is placed on the 2 cans with the upper part oriented towards the free oscillating end of the ramp, and the edges of the cans are placed so that they are uniform with each other. As the ramp begins to move in its arc, a timer is activated automatically. When the ramp reaches the angle at which the third can slides freely from the 2 lower cans, a photoelectric switch deactivates the timer. This is the time, recorded in ße seconds, which is commonly identified as 'time of slip'. The coefficient of static friction e .; equal to the tangent of the angle swept by the ramp at the moment the can begins to move. This angle in cradot * is equal to [4.84 • + (2.79- t)], where t is the sliding time. In some cases, the tested cans were subjected to a bake of 210 ° C for 5 minutes and the COF was re-determined, indicating this result later as 'C0F-2'. The average values for the results of the adhesion test and evaluation of the coefficient of static friction are summarized in Table 2. It was found that the concentrate of lubricant and surface conditioner applied to the clean aluminum cans provided improved mobility to the cans, even with very low use concentrations, and had no adverse effects either on the adhesion of the labels or on the internal lacquer tested, even between 20 and 100 times the concentration of use required to reduce the coefficient of static friction of the cans.

Group 2 Elerorplo These examples illustrate the use of the lubricant and surface conditioner for aluminum cans of Example Group 1 in an industrial can manufacturing plant where the cans pass through the printing station at a speed of; 126C latae per minute. The production of aluminum cans was washed with an acidic cleaner (R doline ™ 125 CC, commercialized by PA) and then treated with a non-chromate co-reverse coating (Aloiine "14404, also marketed by ParkerAm-chem Division, Henkel Corporation , Madison Heights, MI) The production of aluminum cans was then tested to determine slippage and it was determined that the outside of the cans had a coefficient of static friction of approximately 1.63 During the processing of these cans through a station of printing, they were able to pass through said station at a speed of between 1150 and 120C cans per minute, without excessive stumbling, that is, situations of improperly loaded cans.In such a case the cans are not loaded properly on the mandrel doikde are printed Each 'stumble' causes a loss of. ' .Atas to be discarded since they are not acceptable for processing the final stage, Approximately i ml / 1 of lubricant and surface conditioner was incorporated into the deionized rinse water system of the can washer, which resulted in a reduction in the coefficient static friction on the outside of the cans to a value of 1.46 or a reduction of approximately 11% of its original value.Then stepping the cans through the printing station, it was discovered that the adhesion of the outer and inner coating It was not affected by the lubricant and surface conditioner, and the printing speed was requested to be increased to its mechanical limit of 1250 to 1260 cans per minute without new problems, so as to increase the concentration of lubricant and surface asonthi Aqueous deionized water system, it was possible to reduce the coefficient of static friction of the cans by 20% without affect negatively affect the adhesion of the inner and outer coatings of the same. Also, it was possible to keep the speed of the printer continuously at 1250 cans per minute during a 24-hour test period. Example and Comparative Example Group 3 These examples illustrate the use of other materials as a basic component for the lubricant and surface conditioner of the aluminum cans The cans were cleaned with an alkaline cleaning solution with a pH of about 12 to about 41 ° C for about 35 seconds The cans were rinsed and then treated with three lubricants and surface conditioners comprising various phosphate ester solutions Phosphate ester solution 1 comprised an acid phosphate ester (marketed under the trade name of Rhodafac ™ PE 510 from Rhone-Poulenc, Wayne, NJ), at a concentration of 0.5 g / L. Phosphate ester solution 2 comprised an ethoxylated alkyl alcohol phosphate ester (marketed under the tradename Ethfac ™ 161 by Ethox Chemicals , Inc., Greenvi-lle, SC) with a concentration of 0.5 g / L. The phosphate ester solution 3 comprised an ethoxylated alkyl alcohol phosphate ester (sold under the tradename E'thfac ™ 136 from Ethox Chemicals, Inc., Greenville, SC) at a concentration of 1.5 g / L. The mobility of the cans in terms of coefficient of static friction was evaluated and is indicated in Table 3 below.

Table 3 Phosphate ester solution pH Coef. Fric. Static 1 3.6 0.47 2 3.3 0.63 3 2.6 0.77 None 1.63 All the aforementioned phosphate ester solutions provided acceptable mobility to the aluminum cans, but they were completely covered with cuts of the aqueous film. It is desired that the cans be free of cuts in the aqueous film, that is, having a thin continuous film of water, because otherwise they have large drops of water and the aqueous film is not uniform and is discontinuous. To determine if this is adverse for the impression of the cans, they were evaluated to determine the adhesion. That is to say, the cans were cut and opened and boiled in a 1% liquid dishwashing detergent solution (Joy ™), comprising 3: 1 of deionized network water for 10 minutes. The cans were rinsed in deionized and dried water. As in the Example of Gx-upo 1, eight scratches were made on the lining of the cans on the inner and outer side walls and on the inside top. The scratches were x * ecumented with adhesive tape and then the tape was torn off. The cans were classified according to the adhesion values. The average value results are summarized in Table 4, where the values have the same meaning as in Table 2.

For solution 1 of phosphate ester, it was observed that there was almost no detachment on the external side wall, substantial detachment on the internal side wall, and total failure on the internal top of the cans. For the solution 2 of ester of foefato, it was observed that there was almost no detachment on the external lateral wall, and that there was no detachment on the internal side wall or on the internal top of the cans. For the solution 3 of ether of foefato, it was observed that there was no detachment on the external lateral wall, the internal or the internal upper part of the cans. Example of Group 4 This example illustrates the effect of the lubricant and surface conditioner of this invention on the aqueous drainage characteristics of the aluminum cans treated therewith. Aluminum cans were cleaned with a mild cleaner (Ridoline ™ 125 CO, followed by treatment with? .. Lcd.ine ™ 404 or Ridoline ™ 125 CO only) or with an alkaline cleaning solution (process with Ridoline ™ 3060/306) , all of these products being marketed by Parker Amch.em Division, Henkel Corporation, Madison Heights, MI, and then rinsed with deionized water containing approximately 0.3% by weight of the lubricant and surface conditioner of the present invention.

After letting the cans drain as well. rinsed up to 30 seconds,? e determined the amount of water remaining on each can. The same test was performed without the use of lubricant and surface conditioner. The results are summarized in Table 5. It was found that the presence of the lubricant and surface conditioner caused the water to drain evenly from the cans. and that the cans will be free of cuts in the aqueous film for a longer time.

This test is a quality control compression test that determines the column strength of the cans by measuring the pressure at which they are arched. The results are summarized in Table 6. It can be seen from Table 6 that an oven drying temperature of 193 ° C, an increase of 2 pounds per square inch (psi), compared to the value obtained at one tempera oven temperature of 227 ° C, was obtained in the column strength test.

Table 6 Oven temperature (° C) Column strength (PSD 227 86.25 204 87.75 193 88.25 182 89.25 The highest results of the column strength test are preferred and are often required because the thin walls of the finished cans must withstand the pressure exerted from the inside after being filled with a carbonated solution. Otherwise, cans that have weak sidewalls will swell and deform, or may break easily and even explode. It was discovered that the faster drainage of the water film resulting from the presence therein of the lubricant and surface conditioner of the invention, makes it possible to lower the temperature of the drying ovens and in turn obtain higher results of column resistance. More specific, to obtain the proper drying of the rinsed cans, the cans are allowed to drain briefly before entering the drying ovens. The time that the cans can stay in the drying ovens is usually between 2 and 3 minutes, depending to some degree on the line speed, length and temperature of the oven. To achieve adequate drying of the cans in this time frame, the temperature of the oven is commonly about 227 ° C. However, in a series of tests where the rinse water contained approximately 0.3% by weight of organic matter to form a lubricant and surface conditioner of the present invention, it was discovered that satisfactory drying of the cans could be obtained when the temperature of the oven it was lowered to 204 ° C and then to 188 ° C, also obtaining dry cans. Group 6 examples Uncleaned aluminum cans from an industrial manufacturer were washed and cleaned, in Type A examples with alkaline cleaner sold by ParkerAmchem Division, Henkel Corporation, Madison Heights, Michigan, employing the process with Ridoline ™ 3060/306 and in Examples Type B with an acid cleaner, Ridoline ™ 125 CO from the same company. After initial rinsing and before final drying, the 73 The cans were cleaned with a superfluous lubricant and conditioner formed per approximately 1% by weight of active organizer in the (deionized water * as indicated in Table 7 below. Apart from examples, after the initial rinse and before the "final drying", the cleaned cans were treated with a reactive lubricant and surface sealant formed by approximately 1% organic active (Ij in deionized water plus approximately 2g / L ( , 2% by weight) of inorganic (II), as indicated in Table 7 below In another example group, after initial rinsing and before final drying, li piae cans are treated with a lubricant and conditioner surface formed by approximately 1% organic active (I) in deionized water plus approximately 0.5% by weight of surfactant (III) specified in Table 7 below In another group of examples, after initial rinsing and before final drying, l clean cans are treated with a lubricant and reactive surface conditioner forming component, in deionized water, formed by approximately 1% organic active (I), 0.2% inorganic (II), and approximately 0.5% surfactant (III) , as indicated in Table 7 below. In all cases in this group of examples, the COF produced on the surface was less than 1.5.

TABLE 7 Examples and Comparative Examples of Group 7 In this group, various materials for forming a lubricant and surface conditioner were tested with lower concentrations than in Group b '. 7.1 General Procedures. Moisture improver / rinse aid solutions were prepared using deionized water with a conductivity of less than 5 μsiemens; to l Unless indicated otherwise, all other solutions were prepared with network water. Stretched and pressed aluminum cans were obtained, produced from a commercial plant. The largest: cans were tested on a pilot scale washing belt, a seven-stage, single-track washing type conveyor belt (abbreviated 'BW') at its maximum speed of 6. 2 feet per minute Cfpm'5. Alternatively, the aforementioned CCW was used, which processes 14 cans in a sequence of intermittent steps under microprocessor control. Both types of washing machines were able to simulate the sequences, stopping characteristics and extraction of large-scale production washing machines.

The Free Acidity and Fluorine activities of the cleaning baths were determined as indicated in the Technical Process Bulletin of PA (No. 968) for Ridoline 124C. The cleaned and treated cans were dried in an electric forced air oven as indicated below. The mobility of the cans was tested as in Group 1. Lae heights of the foam were determined by placing 5C milliliters ('mL') of the process solution in a graduated cylinder graduated and agitated vigorously for 10 seconds. The total volume of fluid, liquid plus foam, was determined immediately and after five minutes of stationing. These 'foam heights' are identified below as '1FH' (initial foam height) and 'PFH' (persistent foam height), respectively. The cut characteristic of the aqueous film of cans treated with final rinse mobility improvers ('FRME') was evaluated by visually classifying the amount of aqueous film cuts on each of the four major surfaces of the can: the top and Interior side wall and top and exterior side wall. In this classification scheme, a value of 2 is assigned to a surface completely free of aqueous film cuts, zero to a surface completely covered with aqueous film cuts and intermediate intermediate core values. Four cans of this foi-ma were evaluated and the score was added to give a number between 32 and D, the free classification number for cuts in the aqueous film. (WBF) 7.2 Effect of the Fluoride Activity in the Cleaner Bath on COF and Reflectivity. The CCW and subsequent drying oven were used as follows: Stage 1 mains water, 54.4 ° C, 30 sec. Stage 2 RIDOLINE ™ 124C, 15 mL, free acid, 3.4 g total of surfactant, fluoride activity 10 to -20 mV in increments of 10 V, 60 ° C, 60 sec. Stage 3 network water, 90 sec.

Stage 4 deeionized water, 90 sec. Stage! 5 optional application of 0.4% ME-40 ™, 20 sec.

Stage 6 not used Oven for 5 minutes at 210 ° C. (Note: In this description and later of the specific chemical compositions used in various 'Stages', the stage number refers only to the order of the treatment stations of the mechanical equipment used in a train that has six such stations and does not imply necessarily the same chemical types of treatments listed for the mie or stage number in Table 1 are used.) The 'fluoride activity' indicated for the indicated Stage 2 is defined and can be conveniently mediated by means of an electrode sensitive to fluoride as indicated above and in greater detail in the US patent (s) (n). 3431182. The effectiveness of the removal of dirt was measured with the use of the 'brightness tester'. This device consists of a high intensity lamp with stabilized energy and a beam of optical fibers that conduct light to the surface of the can. The light reflected from the can impacted on a photocell whose current output was amplified and converted into a digital reading by an International Microtronics Inc. Model 350 amplifier; the indicated number was recorded as the brightness of the surface. The instrument was calibrated with a flat silver background mirror to a measured reflectivity of 440. Once calibrated, the reflectance of fourteen cans was measured and averaged. With this device it was possible to measure the reflectance1. interior and the reflectivity of the total exterior top. The results are indicated in figures 1 (a) - l (d). These highlights indicate that the brightness increases monotonically within the indicated range with increasing fluoride activity. The values of COF, by contrast, seem to reach the maximum with fluoride activities that correspond to approximately readings of +10 mv and decrease slightly with increases or decreases of that range. The variation of COF with level of fluoride activity in these experiments is really of relative practical importance, compared to the substantial improvement obtained using a suitable FRME material.

If the rebultados indicated in figures 1 (a) - 1 (d) were the only considerations practically important, would favor higher levels of fluoride activity. For various reasons, however, in practice this is not true. High fluoride levels are more expensive and result in high pickling rates that can increase the costs of reducing pollution or even damage the ability of a pickling container to contain pressurized beverages, such as carbonated beverages. Also, in integrated commercial operations where there is a relatively short time between the shaping and cleaning of cans, the oily residues from the can shaping are easier to extract than in the laboratory experiments, where at least a few hours normally elapse. of time between the shaping of a series of cans and their cleaning. As a result of these factors, fluoride activity levels corresponding to electrode readings of between +50 and -10 mv are generally preferred, with electrode readings of between +5 and 0 being most preferred. As would be expected from the results indicated in Figures 1 (b) and 1 (d), the highest fluoride activities within these ranges are preferred when a large brightness of the cans is required. Materials for the FRMEI Activity The CCW was operated according to the following scheme, in which the extended rinsing time of Stage 3 simulated a production sequence where the normal applications of Stage 3, 4 and 5 were used as rinses: Stage 1 sulfuric acid, pH 2.0, 30 sec., 54.4 ° C Stage 2 RIDOLINE ™ 124C, 15 mL, free acid, 3.4 g / L total surfactant, Activity Fluoride -10 V, 90 sec., 54.4 ° C Stage 3 deionized water, 150 sec.

The CCW was charged and operated as described in 7.3 with the exceptions that the aqueous ex-rinse adc from Step 3 was applied for 130 sec. and the first oven treatment was carried out at 200 ° C, instead of 150 ° C. The compositions of Step 4 are indicated in Table 9. The experiment using Trylox ™ 5921 included 0.2 g / L of Igepal ™ CO-887 in a vain attempt to clarify the solution; a slight turbidity persisted even in the presence of the cosurfactant.

The CCW was charged and operated as described in 7.3 with the variations of Step 4 indicated in Table 10. The results in Table 10 indicate that only a very slight defoaming is achieved with these ant.¡ foam. However, smaller amounts of ethoxylate:? of the primary ethoxylated lso-stearic acid lubricant and surface conditioner forming composition resulted in less foam, with COF values that are fully suitable for most applications. The mixtures of the 'deicers' Pluronic ™ 3IR1 and Trycol ™ 6720 with Ethox ™ MI-9 produced slightly more foam than the compositions with an equal total amount of Ethox ™ MI-9 alone, but also gave more reductions in the COF . Some interactions are obviously complex and difficult to predict.

The cans were piled on a lightweight aluminum baking dish and weighed with the tongs, taking care to lose as little water as possible during the manipulations. The cans, tongs and tray were then dried at 210 ° C for 10 'minutes and weighed again. The average of three identical tests was taken as an estimate of the aqueous retention of the finished cans. A fourth group of cans was put together, dried at 10 ° C for 3 minutes and tested to determine its COF. For those cases in which the COF was less than 1.00, COF-2 was determined. The results are shown in Table 11. It was found that some surfactants are better for causing aqueous drainage than ethoxylated isostearic acids which are very effective in providing lubricant and surface conditioner films. However, surfactants that are exceptionally good at causing aqueous drainage are poorer than the ethoxylated isostearic acids to reduce COF. The mixing of the two types allows an improvement in aqueous drainage, while retaining the ability to achieve COF values that are suitable in many applications. 7.7 Amine Oxide and / or Combinations of Quaternary Ammonium Salts with Fluoride. Grant Generals for the Examples and Comparison Models in 7.7 All loe; Examples of processing and comparison examples described below in this section used aluminum cans as substrates and a laboratory prototype simulation of a six-stage commercial processor. Each test was made with 14 cans. The sequence of the process used is described in Table 12. Compositions of Step 4 were prepared, either by dilution of concentrate or directly from the ingredients. To simulate what occurs in a commercial can washing operation, the aluminum level (ie, the stoichiometric equivalent as aluminum of the total of somponenteti (D) and (E) indicated) was adjusted to approximately 100 ppm, to record the drag from Step 3 to Step 4. Additionally, the pH, fluoride activity and concentrations of other components varied with the specific experiment, as indicated below. The cans washed and rinsed according to the six-stage process described above were dried for 5 minutes at 150 ° C under normal conditions, except that when the heat-resistant mobility was being tested, the cans were subsequently placed in a 200 ° oven. C for an additional 5 minutes. These conditions were identified as single or double cooking cans, respectively.

All coefficient of friction determinations were made in the manner described in lines 44-65 of the US patent (s) nro (s). 4944889 and they were the average of 15 individual measurements. The upper parts were extracted from the cans using an opener. Once this was done, they were placed in a 66 ° C water bath containing 0.2 g of sodium tetraborate decahydrate per 1000 mL of deionized water. After immersion for 30 minutes, the upper parts were rinsed with DI water and dried in an oven. The superior stain resistance quality was judged visually with clean cans only (untreated) as a negative control and cans treated with Alodine® 404 as a positive control. Both external and internal top surfaces were inspected.

Notes for Table 12 The composition for Stage 2 contained (i) a commercially available sulfuric acid and surfactant cleaner (RIDOLINE® 124-C PA) at a concentration such as to give 3.4 g per liter of total surfactant and (ii) acid hydrofluoric and, if necessary, additional sulfuric acid to give a free acid value of 15 points and a fluoride activity reading of -.10 mv, using the Orion instrument and associated electrodes, as described above. The free acid points are determined by titrating a sample of 10 mL of the composition, dissolved in approximately 100 ml of distilled water, with 0.10 N of NaOH solution, using a phenolphthalein indicator after dissolving a large excess of sodium fluoride ( approximately 2-3 ml in the gross volume of dry reagent in po3vo) in the sample before titration. The acid points are equal to the number of mL of the titrator required to reach a soft pink end point.

It is a commercial product of Air Products and Chemicals Co. and its supplier reports that it is 2,4,7,9-tet: ramethyl-5-decin-4,7-dicl. In a preferred embodiment of the present invention, it was prepared. working composition incorporating 1% of each of the indicated concentrates of filling to deionized water. and the resulting solution, which had a pH within a range between 2.7 and 2.9 and a fluoride activity value of between -60 and -80 mv relative to the Solution. Standard 120E, was used in Stage 4 to commercially treat aluminum cans D & I for an improvement in mobility, spraying the cans for 25 sec. at 43 ° C. The resulting cans had values of COF-SB that oscillated between 0.5 and 0.6 and a resistance to spotting of the upper part equal to that achieved with Alodine® 404, particularly when the concentration of aluminum cation in the treating composition ranged between ICO-300 ppm. When using the treating composition, the replacement compositions indicated above are incorporated as necessary to maintain the COF and the stain resistance of the upper part. If a joint filling concentrate is required, the following is an example of a preferred concentrate, not indicating the rest, which is water. Ingredient Grams of Ingredient per Kg.

A COF value of less than 0.6 was obtained in several experimental tests over a period of thirteen weeks of concentrate storage. Examples and Comparison Examples Group 8 The combination of ethoxylated castor oil and fluozirconic acid derivatives indicated in Table 8 has an unexpected additional advantage, which is illustrated in greater detail in this group. It has been found that an FRME that combines fluozirconic acid and hydrogenated castor oil derivatives in adequate concentrations provides both protection against upper staining during pasteurization and adequate reduction of COF for most cases. The washing sequence for this group of examples was as follows: Stage 1 Sulfuric acid, pH 2.0, 30 sec., 54.4 ° C Stage 2 'Xidoline ™ 124C, 15 mL, free acid, 3.4 g / LOral surfactant, fluoride activity -10 mV, .90 sec. 54.4 ° C.

Stage 5 r.o used Stage 6 not used In addition to the ingredients listed in Table 7, the solutions were all adjusted to pH 4.5 by the addition of aqueous ammonia or nitric acid, as required.

The spots on the upper part were evaluated by first extracting the upper parts of the cans treated with an opener. The upper parts were then placed in an aqueous bath containing 0.2 g / L borax at 65.6 ° C for 30 minutes, then rinsed in deionized water and dried in an oven. Stain resistance was assessed visually by comparison with known satisfactory and unsatisfactory standards. The results are indicated in Table 20. The last two conditions indicated er. Table 20 are highly satisfactory with respect to both the COF and the stain resistance at the top during pasteurization.

The sequence of the process used in all these examples, unless otherwise indicated, is indicated in Table 22. aqueous film was evaluated in the same way as described later in point 7.1. To simulate commercial operations, in which substantial quantities of lubricating oils are transported to Wash Stage 2 despite the use of an acid prewash, lubricating oils were normally incorporated into the tested compositions of Step 2. Two types of mixtures of Lubricating oils were used. The type of 'Low Irregular Steam' formed by 30% by weight of DTI 5600 -M3 and 70% by weight of DTI 5600- B, while the type of 'High Irregular Steam', was formed by 1/3 by weight of DTI 5600-M3, 1/3 by weight of Atochem SDO-5L-54-N2J, and 1/3; or weight of Mobil 629. (The oils that have the letters 'DTI' in their designations are marketed by Diversi ied Technology Inc., San Antonio, Texas, USA, and the indicated Atochem oil is marketed by Elf Atochem North America, Cornland Heights, Pennsylvania, USA). Also to simulate commercial operations in which substantial amounts of aluminum accumulate in the compositions of Step 2, the Al * 3 concentration of the compositions of Step 2 was adjusted with 3.2 g of sodium aluminate • 1.5 H-0 in 6 liters of the total composition of Stage 2 = 100 ppm of aluminum ions. Historically, sequestrants have been included in alkaline can cleaners to help prevent the build-up of magnesium oxide and staining of can surfaces. These two normally undesirable phenomena are linked to the strongly alkaline conditions necessary to clean the surface of the can well. Classification Group 10.1 A Plackett-Burman approach was used, which is outlined in the previous statistical literature. The input variables studied constituted the best approximation of the critical parameters necessary to consider when designing a product and process of this application. Table 23 below indicates the experimental design. Phosphote-ric® TC-6, according to its supplier, Mona Industries of Ratterson, Jersey Jersey, has an 'R' portion according to the chemical formula (II) below: r 'i wherein at least one of R1 and R3 is carboxyethyl or salt thereof and the other is carboxyethyl, salt thereof, or hydrogen, and R2 is coconut oil alkyl, with the following chemical formula (III): (O-CÍ) ^ CHj-R), 0 = 5", CV (0H? Where u is lo?., Y = (4-u) and M is cation of hydrogen or sodium, except that at least one M must be a cation of Sodium Ethoduoquad® T-15 has, according to its supplier, the following chemical formula: HOCH Hj Taib aiyl-H1. (CHZ)} -N% (CH2CHI0H) J (CKtC0Ü Tallow alkyl = tallow alkyl Lae output variables measured were aqueous film cut, COF, interior gloss and visual appearance. Tables 24 and 25 below summarize the results of this group of examples. Only the confidence coefficients = 80.0% are listed. The sign of the coefficient corresponds to whether the resulting property is maximized at the level (+1) (sign +) or level (-1) (sign -). From the results in Tables 24 and 25, it is evident that the quaternary mobility enhancing additives are much better at preventing aqueous cuts and achieving a lower COF value. In most applications, this makes them preferable for phosphate ester types, even though the phosphate ester types produce slightly higher interior brightness and appearance qualifications.

The pH of the composition of Step 2 was 12.0 or 11.4. The sequestering compositions used are indicated in Table 26.

The 3ß results are indicated in Table 27 and 28. The pH values indicated in these Tables were adjusted with sodium hydroxide.

The results in Tables 27 and 28 indicate that the higher pH of the composition of Stage 2 favored appearance and brightness, while the lower pH favored mobility. Likewise, tartaric acid as the only sequestrant resulted in a poorer interior brightness in most of the conditions that favored this characteristic, thus omitting the following series of experiments. Group 10.3 > Effect of pH and Temperature. Concentrations of Additive Mobility and Lubricating Oil, and Concentration and Type of Sequestrant in the Composition of Stage 2. A statistically designated group of 49 combinations of the series of input variables indicated in Table 29 was evaluated for the four output variables, as in the previous subgroups, in this group. The combinations in this subgroup, in addition to the ingredients indicated in the Table. 29, contained all 2000 ppm of Al * 3 ions and 1.25 mL / L of 'Mixture 1' surfactant, as indicated in the Notes for Table 23.
