Properties of HEDP (Cas No 2809-21-4) Corrosion Inhibitor:
HEDP (Cas No 2809-21-4) Corrosion Inhibitor 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 (Cas No 2809-21-4) Corrosion Inhibitor shows excellent scale and corrosion inhibition effects under temperature 250°C.
HEDP (Cas No 2809-21-4) Corrosion Inhibitor 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).
HEDP (Cas No 2809-21-4) Corrosion Inhibitor can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular.
Therefore, HEDP (Cas No 2809-21-4) Corrosion Inhibitor has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects.
