Description
Technical field
The present invention relates to aluminum alloy chemically frosted and chemical rightenning technology.
Technical background
Chemical sanding smokeless-polishing technology for aluminium alloy is to grow up on the basis of aluminium alloy three acid polishing technology, she has kept most of advantage of three acid polishing technology, simple as technology, brightness is more high, and its weakness carried out deep improvement, as can not drip, can not production frosted material, can not the remaining polishing grey black of automatically removing aluminum alloy surface etc., the world-famous puzzle in these long-term puzzlement aluminium alloy polishing technology fields, by chemical sanding smokeless-polishing technology for aluminium alloy, obtained effective and reasonable solution.
Summary of the invention
The present invention arranges reactive tank to realize by following mode:
| 1# | 2# | 3# | 4# | 5# | 6# | 7# | 8# | 9# | 10# | 11# |
| Chemical sanding | Mirror polish | Washing | Washing | Protect photoxidation | Washing | Washing | Air-dry | Organic sealing | Airing | Oven dry |
Illustrate:
1# chemical sanding groove: this groove major function is under 90-120 ℃ aluminium alloy to be gone mechanical line, dusting and polishing (brightness of suitable approximately three acid polishing 80%); Do not have tobacco in this groove working process, when aluminium alloy took out from this groove, drip did not definitely have current mark arbitrarily, can not spend material yet;
2# mirror polish groove: this groove is equivalent to the three acid polishing groove, is rich in strong oxidizer, can carry out mirror polish to aluminium alloy.Compare with the three acid polishing groove, this groove has following characteristics:
A, closely do not have tobacco, a brightness stability: this groove is added with the smog inhibitor of q.s, and the decomposition of tobacco is thoroughly suppressed, and does not have tobacco extremely; Because it is slower that strong oxidizer decomposes, its concentration ratio three acid polishing groove is stable, so the difference in brightness of different batches aluminium alloy is more much smaller than three acid polishing, has realized brightness stability substantially;
B, brightness increase: the brightness of three acid polishing, and outside the Pass having, also relevant with concentration of heavy metal ion and water content in the polishing fluid with sulfuric acid concentration, phosphoric acid concentration, concentration of nitric acid and temperature.This groove is added with the high price heavy metal of higher concentration, and aluminium alloy is had extremely strong oxidisability, and the interaction of heavy metal and nitric acid had both suppressed tobacco, had increased aluminium brightness again; In addition, the brightness of polishing material is relevant with the polishing fluid water content, and water content is high more, and brightness is low more; Phosphorus acid content is up to 80% in the three acid polishing liquid, and the water content of phosphoric acid is 15%, and the corresponding water-content of tank liquor is not less than 12%; So high water-content must reduce the brightness of polishing material, has also stopped the technological transformation space for we improve brightness simultaneously; Mirror polish liquid concentrates through long high temperature in making processes, water-content less than 5%, so the brightness of mirror polish material obviously improves;
C, drip for a long time: consider that the three acid polishing reaction is too violent, after aluminium alloy leaves polishing fluid, dripping time can not be above 30 seconds, a large amount of polishing fluids are brought into washing bath, cause the too expensive weakness of polishing material cost, are added with the q.s inhibiter in the mirror polish liquid, after the protection aluminium alloy leaves polishing fluid, can not spend material by the random time drip aloft, do not have current mark yet, can save polishing fluid thus more than 70%;
D, automatically ash disposal: when the impure or polishing fluid of aluminium alloy was aging, often there was one deck grey black on polishing material surface, and general method is difficult to remove, and has a strong impact on quality.In chemical sanding groove (1#) and the mirror polish groove (2#), all be added with the ash disposal composition, can remove the polishing ash automatically;
E, yield rate height: because mirror polish groove (2#) has solved problems such as aberration, current mark, flower material, polishing ash, make yield rate significantly improve, thereby reduced cost, improved production efficiency;
5# protects the photoxidation groove: this groove is set two big purposes, promptly the mirror polish material is protected photochemical oxidation and smart ash disposal;
A, guarantor's photoxidation: protect photoxidation groove (5#) and can generate certain thickness oxide film, can keep original brightness fully again.Because anodic oxidation makes mirror polish material loss of gloss, and some aluminium alloy as lamp decoration, casing, utensils etc., does not need thick oxide film, therefore available guarantor's photoxidation method is handled, and behind organic sealing, directly dispatches from the factory, and avoids loss of gloss; In addition, aluminium alloy from the mirror polish to the anodic oxidation before, need the multiple tracks washing, and might be aloft or washing bath be detained, produce spot corrosion, if protect photoxidation groove (5#) earlier, prefabricated certain thickness chemical oxide film, protect in advance, can avoid in washing bath, producing spot corrosion or flower material before the oxidation, improve yield rate;
B, smart ash disposal: the source of polishing ash has two kinds, and the one, doping is arranged in the aluminium alloy, the 2nd, polishing fluid is aging.The polishing ash is difficult to remove with general method, can have a strong impact on the visual appearance of polishing material.Although be added with deashing agent in chemical sanding (1#) and the mirror polish groove (2#), can remove overwhelming majority polishing ash, under some special conditions, still have small amount of residual polishing ash.Protect photoxidation groove (5#) and can thoroughly remove the polishing ash, thereby guarantee polishing material amount;
9# organic sealing groove: this groove is special in protecting the rear treating groove that photoxidation groove (5#) is equipped with.Although aluminium alloy is after protecting the photoxidation processing, the surface is passivation, forms one deck compact oxidation layer, and polishing brightness is completely fixed, and brightening effect is to a certain degree arranged, and also need carry out appropriate oxidative work-up, just can dispatch from the factory.Through multiple comparison, to select repeatedly, the organic sealing scheme is selected in final decision for use, neither influences minute surface material gloss, can thoroughly protect again through the chemical oxide film of protecting photoxidation groove (5#) formation and avoid pollutions such as fingerprint and greasy dirt.
By chemical sanding groove (1#), mirror polish groove (2#), guarantor's photoxidation groove (5#) and organic sealing groove (9#) combination, can produce chemical sanding polishing material, mechanical ash propel polish material and goggles mirror polish material:
A, chemical sanding polishing material: aluminium alloy is put into chemical sanding groove (1#), and 90-120 ℃ was reacted 5-10 minute down, can go mechanical line, dusting, and obtain the brightness of relative three acid polishing 80%; Reaction finishes, and aluminium alloy takes out from chemical sanding groove (1#), and drip 2-3 minute (till the drip-dry) directly advances mirror polish groove (2#), and 90-110 ℃ was reacted 3-4 minute down, improved brightness, takes out then, and washing bath is put in drip-dry (approximately 2-3 minute); (4#) (the washing time is not too long behind the twice water through (3#), in order to avoid spot corrosion), enter rapidly and protect photoxidation groove (5#), normal temperature is 3-5 minute (reaction times is on deciding the chemical oxide film thickness requirement) of reaction down, generate certain thickness chemical oxide film, and further blast and smart ash disposal.Chemical oxide film can protect the polishing material in the residence time before anodic oxidation not by spot corrosion, reduce simultaneously anodic oxidation to the polishing material the loss of gloss degree; After protecting photoxidation,, can carry out anodic oxidation, finish surperficial pre-treatment through the twice washing.For many industrial materials or interior decoration material, after protecting photoxidation, through (6#) (7#) twice washing, the dried groove of air intake (8#) is air-dry, advance organic sealing groove (9#) again, after sealing of hole 1-2 minute, advanced airing groove (10#) airing 5-10 minute, a complete set of surface treatment is finished in the most laggard oven dry groove (11#) baking 25-35 minute.Because aluminium alloy can both drip-dry after chemical sanding groove (1#) and mirror polish groove (2#) take out, reagent consumption is in 150-200Kg/ ton material, than the three acid polishing reduction more than 70%; Simultaneously, the present invention is designed to mirror polish groove (2#) to chemical sanding groove (1#) compatibility, aluminium alloy directly advances mirror polish groove (2#) behind chemical sanding groove (1#), there is not the medicament loss between two grooves, actual dose consumption is the carry-over loss of mirror polish groove (2#), function increases, and cost significantly reduces on the contrary;
B, mechanical ash propel polish material: the sandblast material is directly put into mirror polish groove (2#), 90-110 ℃ of polishing taking-up after 5-10 minute down, drip-dry (approximately 2-3 minute); , put into rapidly and protect photoxidation groove (5#) (4#) after the twice washings through (3#), ash disposal and generate chemical oxide film under the normal temperature, the protection aluminium alloy is avoided spot corrosion, and reduces the anodic oxidation loss of gloss; At last, through the twice washing, can carry out anodic oxidation or organic sealing;
C, goggles mirror polish material: the zero diopter material is divided into two types, promptly throws the zero diopter material with the common zero diopter material of mechanical line with through mechanical polishing, the machine that grinds off mechanical line.As stated above, by mirror polish groove (2#), guarantor's photoxidation groove (5#) and organic sealing groove (9#) combination, can carry out mirror polish to this two classes material.
In the three major types material, chemical sanding polishing material is a new assortment, sandblast and goggles mirror polish material are because mirror polish groove (2#) ability is strong, guarantor's photoxidation groove (5#) effectively reduces the anodic oxidation loss of gloss, and than corresponding three acid polishing material brightness height, market competition strengthens; Mirror polish groove (2#) back is equipped with protects photoxidation groove (5#), is a brand-new technology notion, and industrial material can directly be put on market after photoxidation and organic sealing are handled through protecting, and has kept bright finished brightness fully; The building material can effectively reduce anodised loss of gloss degree after protecting photoxidation.
The present invention by chemical sanding (1#), mirror polish (2#), protect photoxidation (5#) and organic sealing (9#) four procedures are formed, chemical sanding groove (1#) is responsible for oil removing, dewaxes, takes off natural oxide film, is removed mechanical line, the polishing of dusting and suitable three sour 80% brightness; Mirror polish groove (2#) is responsible for the polishing of suitable three sour 120% brightness; Protecting photoxidation groove (5#) is responsible for adding lustre to, thoroughly removes polishing ash, passivation polishing material surface, forms oxide film, avoids spot corrosion and reduce anodised loss of gloss degree; Organic sealing groove (9#) is responsible for the mirror polish material is carried out the not sealing of hole processing of loss of gloss, makes the surface possess self-purification functions such as grease proofing, antifouling.Four procedures depend on each other for existence, and work in coordination, and form the complete and tight chemical sanding smokeless-polishing technology of a cover.Core concept of the present invention is a frosted material mirror polish peace finish mirror polish.
Compare with three acid polishing with common two acid, the present invention has following major technological breakthrough:
1, adopt the complete four grooves combination polishing technology of a cover first, contain all polishing materials, the scope of application is that traditional polishing technology can't be up to reaching.Two acid polishing brightness are not enough, are not suitable for production machinery polishing material; Three acid polishing can not dusting and is removed mechanical line, can not produce chemical sand plane materiel; This cover technology is fit to all polishing materials, is a rare technological breakthrough;
2, introduce chemical sanding polishing trough (1#) first, (90-120 ℃) dusting and remove mechanical line between the high-temperature zone, it is the third chemical etching granulation technology that is different from alkaline etching and acid etching sand face, and the polishing ability that has both suitable three acid polishing groove 80%, collecting dusting, remove line and polish in a groove, is technological innovation of the present invention;
3, introduce guarantor's photoxidation groove (5#) first, polishing and chemical oxidation are connected, effectively reduce the anodic oxidation loss of gloss.Anodic oxidation causes polishing material loss of gloss, is the common recognition of aluminium processing industry, generally all is to seek the way that reduces loss of gloss at anodizing tank itself, is difficult to big technological breakthrough.The present invention seeks beyond anodizing tank first and solves loss of gloss problem approach: promptly use the technical thought of washing photographic fixing in the physiognomy, manage to allow the polishing brightness of aluminium alloy be fixed up in advance, and then carry out anodic oxidation, effectively reduce the luminance loss.Through nearly 3 years concentrating on studies, finally found the ingenious way of dealing with problems, promptly between polishing trough and anodizing tank, be provided with and protect photoxidation groove (5#), the polishing material is carried out the not chemical oxidation of loss of gloss (adding lustre on the contrary) earlier, make aluminum alloy surface generate the very fine and close chemical oxide film of one deck, brightness is fixed up earlier, and then carries out anodic oxidation, effectively reduce loss of gloss; For many industrial materials and interior decoration material, only need carry out organic sealing and just can dispatch from the factory, polishing brightness could 100% reservation!
4, organic sealing material groove (9#) is set first, the minute surface material through protecting the photoxidation processing is carried out the not oxidative work-up of loss of gloss, both thoroughly protected mirror effect, increased anti-pollution function again.
5, thoroughly solve the drip problem first, polishing fluid consumption reduces more than 70%, and yield rate significantly improves.Current mark is the formidable enemy of polishing technology, and the polishing fluid consumption of ton material 400-500Kg, yield rate less than 70% etc. cause by current mark.Through nearly 3 years lucubrate, the present invention has found the powerful inhibiter of a class, forms layer protecting film in aluminum alloy surface, and effective isolation polishing solution during drip makes aluminium alloy avoid the hardship of current mark.All be added with the inhibiter of anti-current trace in chemical sanding groove (1#) and the mirror polish groove (2#), drip arbitrarily after aluminium alloy takes out does not definitely have current mark, yet colored material;
6, thoroughly solve polishing material dust problem first, further improve brightness.Polishing grey black that material is hung, usual way are difficult to thoroughly remove, and directly influence brightness.The present invention has found a kind of special deashing agent, directly adds in chemical sanding (1#) and the mirror polish groove (2#), and automatic ash disposal in the time of polishing has solved polishing material dust problem very dexterously!
7, thoroughly solve polishing tobacco problem first, realized the brightness stability of different batches polishing material.This groove is added with the smog inhibitor of q.s, and the decomposition of tobacco is thoroughly suppressed, and does not have tobacco extremely; Because it is slower that strong oxidizer decomposes, its concentration ratio three acid polishing groove is stable, so the difference in brightness of different batches aluminium alloy is more much smaller than three acid polishing, has realized brightness stability substantially.
