Ibyiza:
HPMA ni uburemere buke bwa polymeride, hamwe nuburemere bwa molekile 400-800. Nta burozi, gushonga mumazi, imiti myinshi nubushyuhe bwumuriro, ubushyuhe bwangirika hejuru ya 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 irashobora kandi gukoreshwa nkinyongera kuri sima.

Ikoreshwa:
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 ifite igipimo cyiza cyo kubuza (98%) hamwe nubunini bwo kwambura ibintu. Iyo ikoreshejwe hamwe nu munyu wa zinc, irashobora kubuza neza kwangirika kwicyuma.

Umutekano no kurinda:
HPMA ni acide, kubwibyo guhura nuruhu, amaso, nibindi bigomba kwirindwa. Karaba n'amazi menshi nyuma yo guhura.
