Meatotino:

HPMA o se polymeride mole mamafa maualalo, ma averesi mole mamafa 400-800. Leai se oona, solu i le vai, maualuga vailaʻau ma vevela mautu, decomposed vevela i luga 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 e mafai foi ona faʻaaogaina e fai ma faʻaopoopoga mo le sima.

Fa'aoga:

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 e lelei le fa'asaina o fua (98%) ma mea e fa'amama ai fua. Pe a faʻaaogaina faʻatasi ma masima zinc, e mafai ona faʻamaeʻaina lelei le pala o le carbon steel.
