*-Hydroxy Ethylidene*1,*-Diphosphonic Acid (HEDP)Â
Â
Properties:
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 **0. 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.
The solid state of HEDP is crystal powder, suitable for usage in winter and freezing districts. Because of its high purity, it can be used as cleaning agent in electronic fields and as additives in daily chemicals.Â
Â
APPLICATIONS:Â
HEDP can be wide used for industrial treatment water as corrosion and scale inhibitor, for example boiler water, cyclic cooling water and water of oil field. In addition, it is used as complexing agent in no cyanide electroplating, as metal cleaner and as stabilizer and fixation in blanch and dye industry. As the scale inhibitor ,it can well inhibit the scale of calcium carbonate. The adding weight concentr ation of active ingredient is ***0mg/l. It often cooperates with dispersion-scale inhibitor in the use.
