Abstract
The present invention provides a compounded water treatment agent which adopts polyasparagic acid as a major agent. The present invention is prepared by that the non-poisonous and non-irritant polyasparagic acid is adopted as a major antiscaling component, tungstate without public hazard is adopted as a corrosion inhibitor, and other auxiliary components are further added to form the multifunctional compounded water treatment agent with corrosion inhibiting and antiscaling functions. Since the water treatment agent does not contain phosphorus, eutrophication can not occur easily, and the public hazard of red tide in peripheral water areas can be prevented from occurring, so that the present invention has the advantages of favorable corrosion inhibiting and antiscaling effects. Compared with the water quality of common tap water, the corrosion inhibition rate of carbon steel can reach 98.27%, and the antiscaling rate of calcium carbonate in water can reach 95.67% when concentrate multiplying factor is 2.5 times.
Description
The present invention relates to a kind of water conditioner, particularly a kind of without phosphorus, have a composite water disposal agent of fouling of preventing and corrosion proof function simultaneously.
As everyone knows, for cooling apparatus and each hotel and building air-conditioning that makes each industrial and mining enterprises can run well, need prevent fouling and anti-corrosive treatment to employed water coolant.At present, the water conditioner kind that is used for cooling apparatus and air-conditioning both at home and abroad is very various, still, these above-mentioned water conditioners all are inhibiter or Scale inhibitors mostly with phosphorus, because of it has eutrophication, be thrown into and easily promote the bacterium algae propagation behind the waters and form " red tide ", cause public hazards.
Document (1) Huo Yuning, Liu Shan, Lu Zhu " research of novel water conditioner poly aspartic acid " (East China University of Science's journal, 2000.26 (3) 298～300); (2) Li Yan, Lu Zhu " tungstate and the effect of poly aspartic acid synergistic slow corrosion and mechanism research thereof " (national water treatment water saving in 2000 and environmental protection fine chemicals exchanging meeting collection of thesis) and (3) " Mixture for Inhibition of Corrosion of Metals; Bayer AG. " respectively the water conditioner that contains poly aspartic acid is reported in (USP.5785896); but leave practical application certain distance is still arranged; therefore; must research and develop a kind of practical value, without phosphorus, readily biodegradable, as to help environment protection green composite water disposal agent that has as early as possible, to satisfy people's needs.
The objective of the invention is to disclose a kind of is the composite water disposal agent of host with poly aspartic acid (being called for short PASA), to overcome the shortcoming of existing in prior technology contaminate environment.
Realize the technical scheme of the object of the invention:
The present invention is main scale inhibition composition with nontoxic, non-irritating poly aspartic acid, with the tungstate that does not produce public hazards is inhibiter, add other auxiliary components again, make full use of each component synergistic effect each other, form a kind of multi-functional composite water treatment medicament with inhibition and scale effect.Said water conditioner is to contain in every liter of pending water:
Poly aspartic acid 1～7mg
Tungstate 5～15mg
Trisodium Citrate 20～40mg
Benzotriazole 0～2mg
Zinc salt 0～3mg
Said zinc salt is zinc sulfate or zinc chloride, and said tungstate is sodium wolframate or ammonium tungstate;
The water conditioner of above-mentioned prescription can be used when normal processing.
Can adopt following proportioning for giving when film is handled, contain in every liter of pending water:
Poly aspartic acid 100～250mg
Tungstate 100～250mg
Trisodium Citrate 300～400mg
Benzotriazole 0～10mg
Zinc salt 0～4mg
Above-mentioned various raw material is the commercially available prod.
The preparation method of above-mentioned water conditioner is a kind of physical mixed method of routine, and various materials are proportionally placed water, mixes to get final product.
Above-mentioned water conditioner is to use like this:
To give the film treatment agent earlier and drop in the water, and give film and handled about 48 hours, dilution is transferred to normal processing concentration then, and is kept.
Water conditioner of the present invention has very significant advantage:
1) not phosphorous, be difficult for producing eutrophication, can prevent to produce " red tide " public hazards in waters on every side.
2) having good inhibition and scale inhibition effect, is water quality with general tap water, and when concentration rate was 2.5 times, the corrosion inhibition rate of carbon steel can reach 98.27%, and the scale inhibition performance of lime carbonate can reach 95.67% in the water.
3) raw material sources conveniently are easy to get, and production cost is lower.
Below will the present invention is further illustrated by embodiment.
Embodiment 1
Place stirred vessel to mix in 4mg poly aspartic acid, 10mg sodium wolframate, 36mg Trisodium Citrate, 1mg benzotriazole, 2mg zinc sulfate and 1 premium on currency, promptly obtain normal processing water conditioner of the present invention.
Embodiment 2
Place stirred vessel to mix in 100mg poly aspartic acid, 200mg sodium wolframate, 350mg Trisodium Citrate, 5mg benzotriazole, 3mg zinc sulfate and 1 premium on currency, promptly obtain the film treating water treatment agent that gives of the present invention.
Embodiment 3
Place stirred vessel to mix in 100mg poly aspartic acid, 200mg ammonium tungstate, 350mg Trisodium Citrate, 5mg benzotriazole, 3mg zinc chloride and 1 premium on currency, promptly obtain the film treating water treatment agent that gives of the present invention.Handled about 48 hours through giving film, dilution is transferred to normal processing then, keeps poly aspartic acid 4mg/l in water, ammonium tungstate 10mg/l, Trisodium Citrate 36mg/l, benzotriazole 1mg/l, zinc chloride 2mg/l can obtain to expect good protection against corrosion, the effect of good antiscale property.
