What is Hydrolyzed Polymaleic Anhydride?
Hydrolyzed Polymaleic Anhydride (HPMA) is a water-soluble polymer derived from maleic anhydride. It is produced by hydrolyzing the anhydride groups of polymaleic anhydride, resulting in carboxylic acid groups. HPMA is commonly used as a scale and corrosion inhibitor in water treatment applications, especially in cooling water systems. It helps to prevent the formation of scale and the corrosion of metal surfaces by forming a protective layer. HPMA is also utilized in other industries such as textiles, paper manufacturing, and oilfield applications.
Hydrolyzed Polymaleic Anhydride Uses
Cooling water systems: HPMA is added to prevent the formation of scale deposits on heat transfer surfaces and to inhibit corrosion of metal components in cooling water systems.
Boiler water treatment: HPMA helps to control scale formation and corrosion in boiler systems, improving heat transfer efficiency and extending equipment lifespan.
Industrial water systems: HPMA is used in industrial processes involving water, such as pulp and paper manufacturing, textile processing, and oilfield operations, to prevent scale formation and protect equipment.
Reverse osmosis (RO) systems: HPMA is added to RO membranes to inhibit scaling caused by minerals and salts, ensuring efficient operation of the RO system.
Detergent formulations: HPMA is used as a builder and chelating agent in detergent formulations, enhancing the cleaning performance by preventing the precipitation of hardness ions.
Hydrolyzed Polymaleic Anhydride Structure
Hydrolyzed Polymaleic Anhydride (HPMA) is a polymer compound with a complex structure. Its structure consists of repeating units derived from maleic anhydride monomers. The maleic anhydride units undergo hydrolysis, resulting in the formation of carboxylic acid groups and anhydride linkages. The polymer chain of HPMA contains both carboxylic acid (-COOH) and carboxylic acid anhydride (-CO) functional groups. The specific structure and arrangement of the polymer chain may vary depending on the degree of hydrolysis and the polymerization process. The presence of carboxylic acid groups in HPMA imparts its excellent scale and corrosion inhibiting properties in water treatment applications.
