Green phosphate-free water treating agent

Abstract

The present invention discloses one kind of water treating agent with corrosion inhibiting and scale inhibiting effect. It includes tungstate, acrylic acid-acrylic ester copolymer, polypropenyl sulfonate and benzotriazole. It has both corrosion inhibiting and scale inhibiting effects, no environmental pollution and no harm to human body, and is one kind of environment friendly green water treating agent.

Description

technical field [0001] The invention relates to a water treatment agent, in particular to a water treatment agent with corrosion and scale inhibition functions. Background technique [0002] During the use of industrial circulating cooling water, it is easy to cause corrosion and scaling obstacles of pipeline equipment. For this reason, the method of adding chemicals is usually used to inhibit corrosion and scaling. At present, there are many kinds of water treatment agents with corrosion and scale inhibition effect, but these water treatment agents all contain phosphate, which can easily cause eutrophication of water quality during water treatment, resulting in environmental pollution. Therefore, the development of an environmentally friendly and environmentally friendly water treatment agent has attracted people's attention. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an environmentally friendly water treatment agent with corrosi...
