Phosphonate antiscalant and corrosion inhibitor such as atmp, hedp, edtmps, dtpmpa, pbtca and dispersant: hpma, ma-aa, aa/amps, paa, paas, pesa, pasp.
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 330íµ. Hpma has obvious threshold effect under high temperature (350íµ) and high phú¿8.3ú¬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 300íµ 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 circulating cool water system, oilfield fill water, crude oil dewatering and low-pressure boilers. Hpma has good scale inhibition (98%) and scale stripping properties. When used together with zinc salts, it can effectively inhibit carbon steel corrosion.

Diethylenetriamine pentamethylene phosphonate sodium is an organophosphorus series scale inhibitor. Its molecular formula is C9H28O15N3P5, and its relative molecular weight is 573.2. Diethylenetriamine pentamethylene phosphonate sodium is non-toxic, miscible with water, has better scale inhibition and corrosion inhibition effect, and has good temperature resistance, which can inhibit the formation of carbonate, sulfate and phosphate scale. Especially when the pH value is 10-11, calcium carbonate still has a good scale inhibition performance, and the scale inhibition effect at this time is 2 to 3 times higher than that of hydroxy-ethylenediphosphonic acid and amino trimethylenephosphonic acid. Another outstanding feature is that the combination with manganese ions has a good corrosion inhibition ability on carbon steel and copper alloys.
