Thepa:

HPMA ke polymeride e tlase ea boima ba limolek'hule, e nang le boima ba limolek'hule tse 400-800. Ha ho chefo, e qhibilihang ka metsing, lik'hemik'hale tse phahameng le botsitso ba mocheso, mocheso o bolileng o ka holimo ho 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 ka boela ea sebelisoa e le li-additives bakeng sa samente.

Tšebeliso:

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 na le inhibition e ntle ea sekala (98%) le thepa ea ho fokotsa sekhahla.
