Product Description

Product Name: HEDP.Na2 Chemical name: Partially neutralized sodium salt of bis hexamethylene triamine penta (methylene phosphonic acid) CAS No. 7417-83-7 Molecular Formular 250 Molecular Weight 731 Chemical Structure SPECIFICATIONS: items index Appearance Colorless to light yellow transparent liquid White powder Active component (HEDP)% 16.5 min 74.0-79.0 Active component (HEDP.Na2)% 20.0 min 89.8 min density (20C)g/cm3 1.12-1.22 -- Fe ppm -- 35 max Phosphorous acid (as PO33-)% -- 3 max Dry weight loss % -- 3-6 PH (1% water solution) 4.0-6.0 4.0-6.0 Properties:HEDP.Na2 is an organophosphonic acid corrosion inhibitor, it can chelate with Fe, Cu, and Zn ions, it can dissolve the oxidized materials, it has good scale and corrosion inhibition effects even under 250C, it is stable under high pH value, not easy to be hydrolyzed, not easy to be decomposed under normal light and heat condition, its acid/alkaline and chloride oxidation tolerance are better than that of other organophosph-onic acids. HEDP.Na2 can form six-ring chelating compounds with metal ions in water system, Ca2+ in particular. HEDP.Na2 has good scale inhibition effects and obvious dissolution threshold effects. When used with other Water Treatment Chemicals, the synergistic effects is better. Usage:HEDP.Na2 is widely used in circulating cool water system, medium and low pressure boiler, oil field water pipelines as scale and corrosion inhibitor in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. In light woven industry, HEDP.Na2 is used as detergent for metal and nonmetal. In dyeing industry, HEDP.Na2 is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP.Na2 is used as chelating agent. Package: For liquid: Normally In 250kg net Plastic Drum, IBC drum can also be used as required. For solid: inner liner polyethylene(PE) bag, outer plastic woven bag, or confirmed by clients.
