DTPMPA has excellent scale and corrosion inhibition and good thermal tolerance ability. DTPMPA can inhibit the scale formation of carbonate, sulfate and phosphate. On situation of alkali environment and high temperature (above 210℃) DTPMPA has better scale and corrosion inhibition effect than other organophosphines. Specification of DTPMPA: items index Appearance Brown transparent liquid Active acid % 48.0-52.0 Phosphorous acid (as PO33-)% 5.0max Chloride (as Cl-)% 12-17 Density (20℃) g/cm3 1.35-1.45 pH (1% solution) 2.0 Fe，mg/L 35 max Usage of DTPMPA: DTPMPA can be used as scale and corrosion inhibitor in circulating cool water system and boiler water, and especially in alkali circulating cool water system without additional pH regulation, It can also be used in oilfield refill water, cool water and boiler water with high concentration of barium carbonate. When used alone, little scale sediment is found even none of dispersant is used. DTPMPA can also be used as peroxide stabilizer, chelating agent in woven & dyeing industry, pigment dispersant, microelement’s carrying agent in fertilizer and concrete modifier. In addition, DTPMPA is used in papermaking, electroplating, acid cleaning and cosmetics. Package and Storage of DTPMPA: Normally In 250kg net Plastic Drum, IBC drum can also be used as required.
