Molecular Formula: C2H6O7P2Na2 
Molecular Weight: 250
CAS Number: 7414-83-7
Application Notes:
HEDP.2Na is widely used in circulating cool water system, medium and low pressure boiler, oil field water pipelines as scale and corrosion inhibitor in fields such as electric power, chemical indust1y, metallurgy, fe11:ilizer, etc.. In light woven indust1y, HEDP.2Na is used as detergent for metal and nonmetal . In dyeing indust1y, HEDP.2Na is used as peroxide stabilizer and dye-f1Xing agent; In non-cyanide electroplating, HEDP.2Na is used as chelating agent.
Recommended Uses:
HEDP.2Na is an organophosphonic acid corrosion inh心tor, it can chelate with Fe, Cu, and Zn ions, it can dissolve the oxidized materials, it has good scale and corrosion inhibition effects even under 250℃， it is stable under high pH value, not easy to be hydrolyzed, not easy to be decomposed under normal light and heat condition, its acid/alkaline and chloride oxidation tolerance are better than that of other organophosph-onic acids. HEDP.2Na can form six-ring chelating compounds with metal ions in water system, Ca2+ in pa11:icular. HEDP.2Na has good scale inhibition effects and obvious dissolution threshold effects. When used with other Water Treatment Chemicals, the synergistic effects is better.
