Istruktural na Formula:
Ari-arian:
HPMA ay isang mababang molekular na timbang polymeride, na may average na molekular na timbang 400-800. Walang toxicity, natutunaw sa tubig, mataas na kemikal at thermal stability, decomposed temperatura sa itaas 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 maaari ding gamitin bilang additives para sa semento.

Paggamit:
HPMA is usually used together with organic phosphonate at dosage of 1-15ppm for circulating cool water system, oilfield fill water, crude oil dewatering and low-pressure boilers. HPMA ay may mahusay na pagsugpo sa sukat (98%) at mga katangian ng pagtatalop ng sukat. Kapag ginamit kasama ng mga zinc salt, mabisa nitong mapigilan ang carbon steel corrosion.
Packaging at imbakan:
200L plastic drum, IBC(1000L), kinakailangan ng mga customer. imbakan para sa isang taon sa makulimlim na silid at tuyo na lugar.
Kaligtasan at proteksyon:
Ang HPMA ay acidic, kaya dapat iwasan ang pagkakadikit sa balat, mata, atbp. Hugasan ng maraming tubig pagkatapos makipag-ugnay.
