The world’s leading manufacturer and supplier of Xanthan Gum, Oil Driling Chemicals, Drilling Fluid Additives, Rubber Plastic Additives and Cosmetic Ingredients.

Properties
HEDP.Na is anganophosphonic acid corrosion inhibitor, it can chelate with Fe, Cu, Zn ions. HEDP.Na can dissolve the oxidized materials, it has good scale corrosion inhibition effects even under 250°C, it is stable under high pH value, not easy to be hydrolyzed, not easy to be decomposed under normal light heat condition, its acid/alkaline chloride oxidation tolerance are better than that of otherganophosph-onic acids. HEDP.Na can form six-ring chelating compounds with metal ions in water system, Ca2+ in particular. HEDP.Na has good scale inhibition effects obvious dissolution threshold effects. When used with other Water Treatment Chemicals, the synergistic effects is better.

HEDP.Na is suitable facidic scale inhibitdetergent, can be used fmetal surface treatment.

Usage
HEDP.Na is used in circulating cool water system, medium low pressure boiler, oil field water pipelines as scale corrosion inhibitin fields such as power plant, chemical industry, metallurgy, fertilizer, etc.. In light woven industry, this product is used as detergent fmetal nonmetal. In dyeing industry, this product is used as peroxide stabilizer dye-fixing agent; In non-cyanide electroplating, this product is used as chelating agent.

When used as scale inhibitor, the dosage 2-20mg/L is preferred, when used as corrosion inhibitor, the dosage 20-100mg/L is preferred, when used as cleaning agent, the dosage 1000-2000mg/L is preferred. Usually, HEDP.Na is used together with polycarboxylic acid .
