Product Parameters

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 330ºC. HPMA has obvious threshold effect under high temperature (350ºC) 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 300ºC 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, petroleum pipeline, and industrial circulating cool water systems. In addition, HPMA has good corrosion inhibition effect when used together with zinc salt. HPMA can also be used as additives for cement.

Appllication

 

1. Efficient scale inhibitor. Mainly used in low and medium pressure boiler, steam locomotive boiler, circulating cooling water system, oil pipeline and flash seawater desalination and other aspects of scale inhibitor, and can be used as the main component of advanced cleaning agent, but also can be used as textile bleaching agent, reduce the ash content of textiles. HPMA still has good scale inhibition and dispersion effect on carbonate under 300ºC, and the scale inhibition time can reach 100h. Because HPMA scale resistance and high temperature resistance performance is excellent, so in seawater desalination flash device and low pressure boiler, steam locomotive, water pipeline and industrial circulating cooling water is widely used. In addition, HPMA has a certain corrosion inhibition, and zinc salt compound effect is better, can effectively prevent the corrosion of carbon steel. HPMA is usually (1~15)*10-6 compound with organic phosphate, used for circulating cooling water, oilfield water injection, dehydration treatment and low-pressure boiler furnace treatment, has a good inhibition of scale generation and peeling old scale, scale inhibition rate can reach 98%.
