Disodium of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid(HEDP.Na2)

Properties:

HEDP.Na2 is anganophosphonic acid corrosion inhibitor, it can chelate with Fe, Cu, Zn ions, it can dissolve the oxidized materials, it has good scale corrosion inhibition effects even under 250°C, it is stable under high pH value, not easy to be hydrolyzed, not easy to be decomposed under normal light heat condition, its acid/alkaline chloride oxidation tolerance are better than that of otherganophosph-onic acids. HEDP.Na2 can form six-ring chelating compounds with metal ions in water system, Ca2+ in particular. HEDP.Na2 has good scale inhibition effects obvious dissolution threshold effects. When used with other Water Treatment Chemicals, the synergistic effects is better.
 

Specification:

Usage:

HEDP.Na2 is widely used in circulating cool water system, medium low pressure boiler, oil field water pipelines as scale corrosion inhibitin fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. In light woven industry, HEDP.Na2 is used as detergent fmetal nonmetal. In dyeing industry, HEDP.Na2 is used as peroxide stabilizer dye-fixing agent; In non-cyanide electroplating, HEDP.Na2 is used as chelating agent.
