Hydrolyzed Polymaleic Anhydride

 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℃.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 can also used as additives for cement. HPMA is usually used together with organic phosphonate at dosage of 1-15ppm for circul...

Polyhydric Alcohol Phosphate Ester

  PAPE is a new variety of water treatment chemical. PAPE has very good scale and corrosion inhibition ability. Because more than one ployethylene glycol group is introduced into the molecule, the scale and corrosion inhibition for calcium scale is improved a lot. PAPE has wonderful inhibition effect for barium and strontium scales. PAPE has admirable scale inhibition capacity for calcium carbonate and calcium sulfate,PAPE can be mixed well with polycarboxylic acid, organophoronic acid, phosphate and zinc salt. PAPE can also be used as scale inhibitor for oilfield and industrial cool water system.
