Property
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
**0oC 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 organic phosphoric acids (salt). 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.
