Description
Technical field
The invention belongs to environment-friendly products technical field, it is related to a kind of composition for water process, and in particular to Yi Zhongyong
In the anti-incrustation corrosion inhibitor of processing cycle cooling water.
Background technology
Solve the problems, such as in recirculated cooling water scale inhibitor typically using polyphosphoric acid, organic phosphoric acid, base co-polymer containing sulfonic acid with
Zinc salt compound prescription.Organophosphor is good due to scale inhibition effect, is widely used in processing industrial water.With the speed of modernization development
Accelerate, water pollution is on the rise.The discharge of either municipal sewage, or industrial wastewater, all for environment bring it is unprecedented
Test.Phosphorus as microorganism nutrient source, the influence to environment increasingly causes the attention of people.Existing corrosion inhibitor formula
In contain chromium mostly, although corrosion mitigating effect is than more significant, but its toxicity can not be ignored.Compared with corrosion inhibiter containing chromium, molybdate and
Tungstates is two kinds of nontoxic, free of contamination corrosion inhibiter, but expensive, limits popularization and application.
The content of the invention
For above-mentioned situation, it is used for it is an object of the invention to provide a kind of efficient, nontoxic, pollution-free, cheap
The composition of water process, it has excellent anticorrosion-antiscaling property, former using nontoxic, without phosphorus, pollution-free, cheap chemical industry
Material is composited, and belongs to completely without phosphorus formula, and calcium phosphate scale will not be formed during use, will not cause eutrophy to water body environment
Change, belong to environmental friendly product, high calcium is especially suitable for firmly and high-alkali hard circulating water treatment, with excellent resistance calcium carbonate and resistance
Calcium phosphate scale function, also good corrosion inhibition.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of composition for water process, it includes following component in parts by weight：10~50 parts of polycaprolactam,
