HPMA hidrolize polimaleik anhidrit, molekül ağırlığı 400-800 arasında değişen, açık sarı renkli likit bir su şartlandırma ajanıdır. suda çözülebilen ve güçlü skala inhibisyon özellikleriyle su şartlandırma formülasyonlarında kullanılan bir kimyasal bileşimdir. Kalsiyum ve baryum sülfat inhibisyonu sağlar.
HPMA 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℃. HPMA has obvious threshold effect under high temperature (350℃) 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℃ with effective time as long as 100 hours. Due to its good scale inhibition and high temperature tolerance properties, HPMA 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 has good corrosion inhibition effect when used together with zinc salt. HPMA can also used as additives for cement.
