Description

technical field

[0001] The invention relates to a composite scale and corrosion inhibitor and its application in the treatment of circulating cooling water, in particular, the present invention relates to a composite scale and corrosion inhibitor containing polyepoxysuccinic acid and its application in circulating cooling water processing applications. Background technique

[0002] Water is an important chemical substance necessary for human survival. With economic development and population growth, the crisis presented by water scarcity is becoming more and more serious. In order to protect the increasingly scarce freshwater resources, on the one hand, people try to achieve large-scale seawater desalination with advanced technology; the only way. Circulating cooling water is a major consumer of water in industrial production. Using high-efficiency water quality stabilization technology to increase the concentration of circulating water is the most direct and effective wa...
