Properties
DTPMPA is non-toxic, easily soluble in acid solution. DTPMPA has excellent scale and corrosion inhibition and good temperature tolerance ability. DTPMPA can inhibit the scale formation of carbonate and sulfate. In alkaline environment and high temperature (above 210°C), its scale inhibition performance is better than other organic phosphine.
Storage
Storage in shady room and dry place.
pH of 1% solution
2.0 max
Application
DTPMPA can be used as scale and corrosion inhibitor in circulating cool water system and boiler water, especially in alkali circulating cool water 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 without using dispersant. DTPMPAA can also be used as peroxide stabilizer (especially under the condition of high temperature, the stability of hydrogen peroxide is very good), as chelating agent in woven & dyeing industry, as pigment dispersant, as oxygen delignification stabilizer, as microelement’s carrying agent in fertilizer, and as concrete additive. In addition, DTPMPA is also used in papermaking, electroplating, metal pickling and cosmetics. It can also be used as stabilizer for oxidizing bactericide.
