HEDP
HEDP can dissolve the oxidized materials on these metalssurfaces. HEDP shows excellent scale and corrosion inhibition effects under temperature 250 Centigrade. 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).
