Properties:
Hpma(hydrolyzed polymaleic anhydride) is a low molecular weight polymeride, with average molecular weight 400-800. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330 centigrade. Hpma(hydrolyzed polymaleic anhydride) has obvious threshold effect under high temperature (350 centigrade) and high ph(8.3)level, suitable to be used in alkaline water system or built with agents. It has good scale inhibition against carbonate and phosphate scales under temperature 300 centigrade with effective time as long as 100 hours. Due to its good scale inhibition and high temperature tolerance properties, hpma(hydrolyzed polymaleic anhydride) is widely used in desalination plant of flash vaporization equipment, low pressure boiler, steam locomotive, crude oil evaporation, petroleum pipeline, and industrial circulating cool water systems. In addition, hpma(hydrolyzed polymaleic anhydride) has good corrosion inhibition effect when used together with zinc salt. Hpma(hydrolyzed polymaleic anhydride) can also used as additives for cement.
