Water Treatment Chemicals Phosphonate Corrosion Inhibitor HEDP.Na/ 29329-71-31

Water Treatment Chemicals Phosphonate Corrosion Inhibitor HEDP.Na/ 29329-71-3 is an organic phosphonic acid corrosion inhibitor, with iron, copper, zinc and other metal ions to form stable complexes, can dissolve the metal surfaces. At 250 ℃ can still play the role of a good scale and corrosion inhibitor, remains stable under high pH, hard to be hydrolyzed, usually difficult to decompose under the conditions of light and heat. Acid and alkali resistance, resistance to chlorine oxidation are better than other organic acids (salt).1-hydroxyethanediphosphonic Acid Sodium Salt, HEDP.Na can react with metal ions in water system to form hexa-element chelating complex with calcium ion in particular.Therefore,it has good antiscale and visible threshold effects.When built together with other water treatment chemicals,it shows good synergistic effects .HEDP Na is most suitable for scale inhibition agents and acid detergent formulations, HEDP Na is a cross-hydroxy-B-diphosphonic acid monosodium salt, for metal cleaning, metal processing and metal ion control and other applications. HEDP Na widely used in electric power, chemical, metallurgy, fertilizer and other industrial cooling water system and the low pressure boiler, oil field water injection and oil pipeline scale and corrosion inhibition; HEDP Na in the textile industry, can be used for metal and non- metal cleaning agent, bleaching and dyeing industry peroxide stabilizer and dye-fixing agent, non-cyanide electroplating industry complexing agent.
