Hedp.na (Monosodium Of 1-hydroxy Ethylidene-1,1-diphosphonic Acid)

Our offered HEDP.Na (Monosodium of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid) is an organophosphonic acid corrosion inhibitor, it can chelate with Fe, Cu, and Zn ions, HEDP.Na can dissolve the oxidized materials, it has good scale and corrosion inhibition effects even under 250oC, it is stable under high pH value, not easy to be hydrolyzed, decomposed under normal light and heat condition, its acid and alkaline and chloride oxidation tolerance are better than that of other organophosphonic acids. HEDP.Na can form six-ring chelating compounds with metal ions in water system, Ca2+ in particular. HEDP.Na has gool scale inhibition effects and obvious dissolution threshold effects. When used with other water treatment agents, the synergistic effects is better.

HEDP.Na is suitable for acidic scale inhibitor and detergent, can be used for metal surface treatment.
