Omadused:

HPMA on madala molekulmassiga polümeriid, keskmise molekulmassiga 400-800. Mürgine, vees lahustuv, kõrge keemilise ja termilise stabiilsusega, lagunemistemperatuur üle 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 saab kasutada ka tsemendi lisandina.

Kasutamine:

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 sellel on head katlakivi inhibeerimise (98%) ja katlakivi eemaldamise omadused. Kui seda kasutatakse koos tsingisooladega, võib see tõhusalt pärssida süsinikterase korrosiooni.
