1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP) For Sale, Most Competitive Price, Fast Delivery, Custom Service, Wholesale 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP), Made in China, High Quality Products!, China HEDP, acid corrosion inhibitor. Supplier, Manufacturer.
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 250℃. 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). 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.
