Description
Technical field
The invention belongs to technical field of chemistry, specially refer to a kind of multi-functional phosphate glass water conditioner of controllable release, it has scale inhibition, inhibition and antimicrobial effect simultaneously.
Background technology
As everyone knows, water is in use because calcium, magnesium ion and dissolved CO wherein in the water
2Combining easily forms lime carbonate or carbonic acid magne-scale, and the formation of these dirts can increase the resistance of water, and hydraulic pressure is increased, the flow velocity of water is slack-off, also can stop up water pipe when serious, need the occasion of heat exchange, even can blast because dirt hinders the carrying out of heat exchange at some.Tap water is often introduced chlorine as sterilizing agent in treating processes, thereby certain chlorion arranged in water, and water supply piping system is mainly soft steel at present, chlorion has the intensive erosion action to soft steel, as often " red water " and " yellow water " occurring in the city tap-water is exactly this erosive result, drink this kind water can to human body cause infringement, fouling simultaneously and corroding the work-ing life that also can reduce waterworks.In addition, along with the further raising to water quality requirement, the amount of bacteria in the water also should be controlled within certain scope, and therefore, water conditioner is used for scale inhibition, inhibition or the germicidal treatment of water more.But at present used water conditioner mostly is poly-phosphate, molybdate and the organism compound anti-incrustation corrosion inhibitor mutually of organic water conditioner or crystal type, provides a kind of a kind of composite water disposal agent of being made up of PAPE, vinylformic acid-acrylate-maleic anhydride copolymer, tetradecyl benzyl dimethyl ammonium chloride etc. as Chinese patent CN1240769A.Chinese patent CN1231346A provides a kind of a kind of inhibiter of being made up of Sodium orthomolybdate, tripoly phosphate sodium STPP, nitranol and primary zinc phosphate.But it is fast that these two a little water conditioners all exist in water dissolution rate, delivering medicament often, charging capacity is difficult to shortcomings such as control, in addition, some organic uses form new pollution to water quality.In the external patent more existing adopt phosphate glasses to be used for the report of water treatment, disclose a kind of phosphate glass of germicidal action as US 6143318, but the phosphate glass that has scale inhibition, inhibition and antimicrobial effect simultaneously yet there are no report.
Summary of the invention
The objective of the invention is to shortcoming at above-mentioned patent, providing a kind of can dissolve with certain speed in water, phosphate glass with scale inhibition, inhibition and antibacterial effect, the chemical stability of this glass in water can be adjusted by changing its component, to adapt to different quality and environment requirement.
Design of the present invention is as follows:
Utilize poly-phosphate that the phosphate glass poor chemical stability can dissolve in water, discharge with certain speed in water for the calcium carbonate crystal that has generated, play dissemination, crystal is grown up slowly, the sedimentary appearance of drawing up effectively.Poly-phosphate and calcium, magnesium, iron ion form monocycle or dicyclo inner complex,, are distributed in the water deflate incrustation progressively, cleanser conduit again the solid that has generated on the tube wall.The generation of poly-phosphate and iron ion inner complex has stoped the oxidation of corrosion product iron ion to generate ironic hydroxide, thereby has eliminated ducted " red water " phenomenon effectively.In addition, introduce silver, copper, the zine ion with anti-microbial effect in phosphate glass, in the use, these ions can be dissolved in the water with ionic species by vitreous state phosphoric acid salt, and the solvability of glass in water can be adjusted by changing its component.

Founding of glass is summarized as follows:
Because the Vanadium Pentoxide in FLAKES deliquescence that easily absorbs water is volatile in heat-processed, so the phosphorus composition in the glass is introduced so that Vanadium Pentoxide in FLAKES and phosphoric acid salt are common.In founding, to prevent Vanadium Pentoxide in FLAKES volatilization under the high temperature, glass ingredient is departed from.
The dissolution rate of glass is that the phosphate glass with definite shape and volume is suspended in the vinyon bottle that 250ml deionization solution is housed, and sealing is positioned over 35 ℃ of waters bath with thermostatic control, changes drawing the glass dissolution rate according to weight of glass in the certain hour.
The scale-inhibiting properties of glass is by glass being placed the deionized water solution that deposits lime carbonate or magnesiumcarbonate, being changed by lime carbonate and magnesiumcarbonate before and after the dissolving of X ray test glass behind the 24h.Explanation glass scale-inhibiting properties was good when lime carbonate or magnesiumcarbonate crystal were become unformed shape and the aqueous solution and kept clear by the crystal attitude.
The corrosion inhibition of glass be will the same size in polishing back A3 steel branch add to be positioned over and be added with phosphoric acid salt and do not add in the polymer solution in water of phosphate glass, judge the corrosion inhibition of glass behind the 96h according to the changes in weight of A3 steel.
The anti-microbial property of glass is measured with colony counting method, and being about to glass is 6 * 10 at 50ml volume intestinal bacteria starting point concentration
4After placing 60min in the aqueous solution of individual/ml, represent by the percentage that bacteria content in the water changes.
Advantage of the present invention and positively effect:
A kind of multi-functional phosphoric acid glass water conditioner, the soluble glass that it is made up of phosphoric acid salt and silicate, by the phosphate radical of phosphate glass and the polymkeric substance of the magnesium in the water, iron ion formation monocycle or dicyclo, the solid that has formed on the tube wall, again be distributed in the water deflate incrustation progressively, cleanser conduit, reach the effect of scale inhibition, rust inhibition, reach bactericidal effect by in glass basis, adding ion with antimicrobial effect.Because phosphoric acid salt has the low characteristics of glass melting temperature, this glass and the molten system technology of production are comparatively simple, its dissolution rate can be controlled by the adjustment of component, to adapt to different water quality and environmental requirement, therefore be used for the multiple water treatment requirement, can be widely used in industrial circulating cooling water system, boiler, in multiple water treatment requirements such as air-conditioning, heating pipeline, tap water processing.

Press the accurate raw materials weighing of component shown in the table 1, behind each raw material thorough mixing, under 180 ℃ of conditions, be incubated 2h, under 900 ℃ of conditions, found 2h then, be cast in the cast iron mould of preheating, after 300 ℃ of annealing coolings, promptly obtain fine and close strip uniformly or catch up with spherical multi-functional phosphate glass.
The molar percentage that table 1. glass is formed
| Glass ingredient (mol%) | Embodiment 1 | Embodiment 2 |
| P 2O 5 | 59 | 59 |
| Na 2O | 23 | 9 |
| CaO | 5.5 | 5 |
| SiO 2 | 6 | 5 |
| TiO 2 | 0.1 | 0.1 |
| K 2O | 1.5 | 16 |
| MgO | 4 | 5 |
| Al 2O 3 | 0.4 | 0.4 |
| Ag 2O | 0.5 | 0.5 |
| CuO | 0 |
The dissolution rate and the anticorrosion-antiscaling property of two kinds of glass of table 2. are as shown in the table:
| Glass properties | 1 | 2 |
| Dissolution rate (mgcm -2·d -1) | 3.2 | 5.8 |
| Scale-inhibiting properties | Excellent | Excellent |
| Corrosion inhibition | Excellent | Excellent |
| Sterilizing rate | 99.98 | 99.94 |
Obviously, phosphate glass of the present invention not only has anticorrosion-antiscaling property, also has good antimicrobial property, thereby be applicable to the multiple water treatment needs, the advantage of this phosphate glass is that its component can adjust according to different purposes, and because glass is linear whole dissolving in water, does not need subsequent disposal after the dissolving, cost is very low, has extensive market prospects and good economic benefit.
