Application Notes: HEDP is an organophosphoric acid corrosion
inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable
chelating compounds.It can dissolve the oxidized materials on
these metals’ surfaces. HEDP shows excellent scale and corrosion
inhibition effects under temperature **0°C. HEDP has good
chemical stability under high pH value, hard to be hydrolyzed,
and hard to be decomposed under ordinary light and heat
conditions. Its acid/alkali and chlorine oxidation tolerance are
better than that of other organophosphoric acids (salt).
Recommended Uses: HEDP can react with metal ions in water system
to form hexa-element chelating complex, with calcium ion in
particular. Therefore, HEDP has good antiscale and visible
threshold effects. When built together with other water treatment
chemicals, it shows good synergistic effects.
