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.
