Diethylene Triamine Penta (Methylene Phosphonic) Acid - Dtpmpa-50%

PHOSPHOMAN-235 is safe, easy to be dissolved in acid solution. It has excellent scale and corrosion inhibition and good thermal tolerance ability. It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds. It is the best
silica inhibitor even at severe conditions. Stable with oxidizing agents like chlorine. It can dissolve the oxidized materials on these metals' surfaces. PHOSPHOMAN-235 shows excellent scale and corrosion inhibition effects under very high temperature. It has good chemical stability under high pH value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. Its acid/alkali and chlorine oxidation tolerance are better than that of other organophosphonic acids (salt).
PHOSPHOMAN-235 can inhibit the scale formation of carbonate, sulfate and phosphate. In situation of alkali environment and high temperature (above 210A C) it has better scale and corrosion inhibition effect than other organophosphates.
