  1, Properties and usage:

  HEDP·Na2 is an organophosphonic acid corrosion inhibitor , 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·Na2 can form six-ring chelating compounds with metal ions in water system,Ca2+ in particular . HEDP·Na2 has good scale inhibition effects and obvision dissolution threshold effects.When used with other Water Treatment Chemicals,the synergistic effects is better.
