HEDP(1-Hydroxy Ethylidene-1 1-Diphonic Acid) 2809-21-4:
HEDP(1-Hydroxy Ethylidene-1 1-Diphonic Acid) 2809-21-4 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(1-Hydroxy Ethylidene-1 1-Diphonic Acid) 2809-21-4 shows excellent scale and corrosion inhibition effects under temperature 250°C. HEDP(1-Hydroxy Ethylidene-1 1-Diphonic Acid) 2809-21-4 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(1-Hydroxy Ethylidene-1 1-Diphonic Acid) 2809-21-4 can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP(1-Hydroxy Ethylidene-1 1-Diphonic Acid) 2809-21-4 has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects.
