Green scale corrosion inhibitor

Abstract

The present invention relates to a green antiincrustation corrosion inhibitor. It is formed from (wt%) 10%-35% of polyepoxy sodium succinate (PESA), 0%-35% of sodium wolframate (Na2WO4), 20%-48% of sodium benzoate (NaBz), 0%-5% of benzotriazole (BTA) and 5%-12% of zinc ion (Zn2+). Said invention can be used in industrial circulating water, and can prevent circulating water from producing incrustation, corrosion and algae breeding, as compared with existent product its dose is low, and its antiincrustation and corrosion inhibiting power is strong.

Description

Technical field

[0001] The invention provides a chemical agent for preventing scaling, corrosion, and bacteria and algae growth of industrial cooling circulating water, and belongs to the technical field of chemical engineering water treatment agent production. Background technique

[0002] At present, the scarcity of water resources has become one of the crises faced by our country and the whole world. It is imperative to save water and improve the utilization rate of water resources. Therefore, water saving must first start from industry and agriculture, which use relatively concentrated water. Since cooling water accounts for 60%-70% of industrial water, undoubtedly, saving cooling water has become a major issue of industrial water saving. Cooling water can be divided into direct cooling water and circulating cooling water. The former discharges the water used for cooling directly, so it consumes a lot of water; the circulating cooling water cools the water cooled by wa...
