Abstract
An environment protection type composite water-treating agent is prepared from poly-aspartic acid, RE material ECH, molybdate, benzotriazazole and Zn salt. Its advantages are low corrosion, poison and nutrition, and high safety.
Description
Technical field
The present invention relates to a kind of industrial cycle water conditioner, the composite water disposal agent that has the corrosion-mitigation scale-inhibition function in the time of particularly a kind of safety non-toxic, environmental protection.
Background technology
In present industrial cycle water conditioner technology, the phosphorus that mostly is of widespread usage is water conditioner, the water conditioner of series such as chromium system, nitrite.And phosphorus is the eutrophication that water conditioner can cause water body, causes bacterium algae propagation and environmental pollution; Though cost such as chromic salt, nitrite is lower, toxicity is big, and all there is strict requirement in environmental administration to the discharging of these materials.In addition, above-mentioned water conditioner also can only play single scale inhibition or single corrosion inhibition.MCG Lone in 1984, K.J.[CA 10121616j] point out that molybdate all has corrosion inhibition to carbon steel and non-ferrous metal in cooling water system.But single molybdate inhibiter corrosion mitigating effect is relatively poor, and cost is higher.Huo Yu in 2000 coagulates and waits people [Huo Yuning, Liu Shan, Lu Zhu. the research of novel water conditioner poly aspartic acid. East China University of Science's journal, 2000.26 (3) 298～300] environment-friendly dirt dispersion agent poly aspartic acid is reported to also have a segment distance but simple poly aspartic acid leaves actual application.
Summary of the invention
The objective of the invention is to study the composite water disposal agent prescription of a kind of safety, environmental protection, can overcome shortcomings such as body eutrophication that water conditioners such as phosphorus system, chromium system, nitrite system bring and toxicity height, can overcome low corrosion inhibition rate and expensive shortcoming in the above-mentioned known technology again, environmental type dirt dispersion agent and inhibiter is composite, make full use of the mutual synergistic effect of each component, form a kind of multifunctional safe environment-friendly type water treatment agent with inhibition and scale effect.
The present invention is achieved by the following technical solutions: the prescription of composite water disposal agent is made of six kinds of medicaments, and they are respectively poly aspartic acid, ECH rare earth material, molybdate, benzotriazole and zinc salt.Wherein, molybdate belongs to anode type water conditioner through the chemical process test; Containing active ingredient in the ECH rare earth material, be commonly used for dispersion agent, stablizer and catalyzer, both can carry out galvanic protection after tested, can carry out anodic protection again, is a kind of inhibiter of excellent property; Zinc salt is a kind of cathode type inhibiter; Benzotriazole also has specific corrosion inhibition.More than the common use of four kinds of water conditioners have synergistic effect, its result has not only reduced the consumption of various single component inhibiter such as tungstate, and has significantly improved corrosion inhibition rate.By each medicament intrinsic synergistic effect in the prescription, make this water treatment agent prescription not only have very high scale inhibition function, also have corrosion inhibitive function efficiently simultaneously.
The component and the content of this water conditioner comprise:
Poly aspartic acid 1-10mg/L
ECH rare earth material 0.1-2mg/L
Molybdate 0.1-20mg/L
Benzotriazole 0.1-5mg/L
Zinc salt 1-3mg/L
Said molybdate is a kind of in ammonium molybdate, the Sodium orthomolybdate, and said zinc salt is a kind of in zinc sulfate or the zinc chloride.The water conditioner of above-mentioned prescription can use when normal processing.
Carry out pre-film when handling, above-mentioned water conditioner can adopt following proportioning:
Poly aspartic acid 100-250mg/L
ECH rare earth material 1-10g/L
Molybdate 100-250mg/L
Benzotriazole 1-10mg/L
Zinc salt 1-4mg/L
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:
Earlier prefilming agent is dropped in the water, pre-film was handled about 48 hours.Dilution is transferred to normal processing concentration then, and is kept.
Beneficial effect
Water conditioner of the present invention has the following advantages:
1) not phosphorous, be difficult for causing the eutrophication of water body, cause bacterium algae propagation and environmental pollution.
2) have good inhibition and scale inhibition effect.Tap water with the East China is a water quality, and the corrosion inhibition rate of carbon steel reaches more than 98.5%, and the scale inhibition performance of lime carbonate can reach more than 98.0% in the water.This prescription can disperse water medium clay soil particle, CaCO3, CaSO4, BaSO4, Fe2O3, TiO2, Zn (OH) 2, Ca3 (PO4) 2, Mg (OH) but 2, throw out and scale inhibition such as Mn2O3.
3) the host poly aspartic acid is non-toxic and non-pollution water treatment agent, and biodegradable in water, can not cause secondary pollution.
4) adding of ECH rare earth material has greatly improved the synergistic effect of prescription, and makes prescription be applicable to " four height " water quality of high temperature, high-alkali, high chlorine root and high pH value.
5) molybdate and poly aspartic acid synergy is fairly obvious.Compare with tungstate, molybdate is nontoxic, and is very little to the pollution of environment, and required concentration is less when handling.
6) molybdate in water with the effect of steel matter, form ferrous-high ferro-molybdenum chromium and close oxide compound with provide protection, iron and steel is had the excellent effect of corrosion inhibition.
In order to understand essence of the present invention better, below by embodiment the present invention is further detailed, but does not limit protection scope of the present invention.
