The effect of synthesized hydrolyzed polymaleic anhydride (HPMA) on the crystal of calcium carbonate

Introduction Water used in the cooling water systems usually contains particles, organic matters and scale-forming irons containing Ca 2+, Mg 2+, CO 32?, SO 42? and HCO 3? [1]. The constituents could be concentrated many times (typically 4¨C8 times) because of the evaporative loss of water.

HPMA Chemical, Hydrolyzed Polymaleic Anhydride, HPMA - IROWATER

Hydrolyzed polymaleic anhydride is a phosphorus-free water treatment chemical. It forms a chelate with calcium and magnesium ions in water. And hydrolysed polymaleic anhydride can cause lattice distortion. After the anion is adsorbed by the calcium carbonate nucleus, the nucleus can be charged.
