Poly(maleic acid) Use and Manufacturing

Uses

Hydrolyzed Polymaleic Anhydride has high stability and temperature resistance. It also has a significant solubility limit effect at a pH of 8.3. It can chelate with calcium, magnesium and other plasma ions in the water and has lattice distortion ability, which can improve the fluidity of sludge. Especially suitable for scale inhibition of high temperature water system such as boiler furnace water. It can be used as sediment inhibitors, scale inhibitors, etc. in oil field water pipelines, circulating cooling water systems and flash evaporation seawater desalination. It can also be used as a basic industrial detergent.
