Product Description
Properties : 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℃. It 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 a 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.
It is widely used in desalination plant of flash vaporization equipment, a low pressure boiler, steam locomotive, crude oil evaporation, petroleum pipeline, and industrial circulating cool water systems. In addition. It has a good corrosion inhibition effect when used together with zinc salt. It can also used as additives for cement.
