Hydrolyzed polymaleic anhydride is a polycarboxylic acid organic compound, which is resistant to high temperature and can chelate calcium, magnesium, iron, etc. in water. It has good thermal stability, uses PH range, and has a wide water hardness, making it an excellent scale inhibitor. Hydrolyzed polymaleic anhydride (HPMA), as a low-cost and high-performance green water treatment agent, has become an important member of high-efficiency water-soluble scale inhibitor and dispersant. Especially under harsh environmental conditions such as high temperature, high pH, high alkalinity, high hardness, etc., hydrolyzed polymaleic anhydride has a significant anti-scale effect on calcium carbonate, calcium sulfate, etc., which is beyond the reach of general polyacrylic acid and other organic copolymer dispersants. At the same time, hydrolyzed polymaleic anhydride has low toxicity, no carcinogenic, teratogenic effect, and is often used as circulating cooling water, water treatment agent for water in low-pressure boiler furnaces, and anti-scale treatment of oilfield water injection, crude oil dehydration and other systems.
