Abstract

The invention provides a high-efficiency circulating water treatment agent and an application thereof. The agent is prepared through compounding a main agent phosphonocarboxylate, a sulfonic acid-containing weak acidic nonionic polybasic high-molecular polymer, a high-performance homopolymer, polyepoxysuccinic acid, a high-performance dispersant, and a corrosion inhibitor has a good oxidation resistance. The high-efficiency circulating water treatment agent has an excellent scale inhibition effect on high-temperature, high-hardness and high-concentration water, and can effectively stabilizer carbonates, zinc salts and other turbid substances in the water.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a high-efficiency circulating water treatment agent and its application. Background technique [0002] During the daily operation of circulating cooling water, due to continuous evaporation and concentration, harmful ions in the water will multiply, which will lead to scaling, corrosion and slime growth, resulting in reduced heat transfer efficiency of heat transfer equipment and shortened service life; resulting in blockage Water pipelines, increased pressure resistance, corrosion and perforation and other hazards affect the normal operation of the device. In order to prevent the above water quality obstacles and ensure the safe, efficient and full-load operation of the device, it is necessary to stabilize the water quality of the circulating water. Sulfuric acid circulating cooling water system, water cooler equipment generally occurs in the following sit...
