Abstract

The invention provides a novel scale and corrosion inhibitor for circular cooling water treatment. The inhibitor is characterized by being a composite of chemical materials which are nontoxic, phosphorus-free, pollution-free and low in price. The inhibitor belongs to the phosphorus-free formula; no scale of calcium phosphate is formed in use; the sewage generated by using the formula causes no eutrophication pollution to the environment; and thus the inhibitor is an environment friendly product. The scale and corrosion inhibitor in the invention possesses good general properties, excellent CaCO3 and Ca3(PO4)2 scale inhibiting ability, and good capability to stabilize Zn2+ in water and corrosion inhibiting ability. The scale and corrosion inhibitor can increase the concentrate multiplying factor of the circulating cooling water and be used when the sum of calcium hardness and total alkalinity is up to 1200 mg/L after circulating water is condensed. The inhibitor can substitute present scale and corrosion inhibitors.

Description

A kind of anti-incrustation corrosion inhibitor of cycle for the treatment of water coolant
Technical field: the present invention relates to a kind of novel anti-incrustation corrosion inhibitor of cycle for the treatment of water coolant, be used for the processing of industrial circulating cooling water.
Background technology: the recirculated water prescription mainly is to solve the scale inhibitor problem, generally adopt polyphosphoric acid, organic phosphoric acid, contain the sulfonic group multipolymer, with the zinc salt compound prescription.Organophosphorus is widely used in the prescription for the treatment of agent of process water because scale inhibition effect is good.Along with the speed of modernization development is accelerated, pollution is on the rise, and no matter is municipal effluent, or the discharging of trade effluent, all is that environment has brought unprecedented test.Phosphorus more and more causes people's attention as the nutrition source of microorganism on the impact of environment.Water conditioner imperative without phosphatization.The inhibiter that contains the chromium prescription, the effect highly significant, but its toxicity has limited its use.As seen the development of water conditioner and environment protection must combine closely.Comparing molybdate and tungstate with the former is two kinds of inhibiter of two kinds of nontoxic pollution-frees, but it is expensive, has affected to apply.
The object of the present invention is to provide a kind of water coolant anti-incrustation corrosion inhibitor of efficient, nontoxic, pollution-free, cheap, wide spectrum.
Summary of the invention: the invention provides a kind of novel anti-incrustation corrosion inhibitor of cycle for the treatment of water coolant, it has excellent anticorrosion-antiscaling property, and its characteristics are to have adopted nontoxic, without phosphorus, pollution-free, cheap industrial chemicals to be composited.Belong to completely without the phosphorus prescription, can not form calcium phosphate scale in the use procedure, can not cause eutrophication pollution to environment with the effluent of this prescription institute, belong to environmental friendly product, especially be fit to the hard and high-alkali hard circulating water treatment of high calcium.Anti-incrustation corrosion inhibitor good combination property of the present invention has good resistance CaCO 3With resistance Ca 3(PO 4) 2The dirt function also has Zn in the satisfactory stability water 2+Ability and corrosion inhibition.Be applicable to the circulating cooling water treatment, can improve the cycles of concentration of recirculated cooling water, as can be after recirculated water be concentrated calcium hardness and total alkalinity sum reach in the situation of 1200mg/L and use the water purification agent of alternative present use.
Each composition of the present invention is in mass ratio: polyetheramides (5-60%), polyepoxy sodium succinate (2-30%), Sodium Benzoate (2-30%), sodium tetraborate (2-30%), polymaleic anhydride (2-50%).
