    Cleaning Agent Corrosion Inhibitor 98% Solid HEDP For Water System Cas 2809-21-4

    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. HEDPshows excellent scale and corrosion inhibition effects under temperature 250℃. 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.

    Application of Scale and Corrosion Inhibitor HEDP

    • It is a scale inhibitor and corrosion inhibitor for boilers and heat exchangers, a complexing agent for cyanide-free plating, a chelating agent for soaps, a cleaning agent for metals and non-metals.
    • It is often used as a scale and corrosion inhibitor in boiler water, circulating water, and oilfield water injection treatment. Often formulated with polyhydroxy acid scale inhibitors and dispersants. It can also be used as a cyanide-free plating complexing agent, a fixing agent for bleaching and dyeing industry, and a hydrogen peroxide stabilizer.
    • This product is the main material for cyanide-free plating. It is formulated into a cyanide-free copper plating solution, and the copper plating layer directly on the steel has good bonding strength. The coating is smooth and the color is good. The general dosage is 60% and the content is 100-120 ml/L. The amount of copper sulfate is 15-20 g/L. In addition, before plating, the plated parts are immersed in the 1% to 2% solution of the product to turn the plated parts into an activated state, and then electroplating can further improve the effect.
    • HEDP is used as scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. In light woven industry, HEDP is used as detergent for metal and nonmetal. In dyeing industry, HEDP is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP is used as chelating agent. The dosage of 1-10mg/L is preferred as scale inhibitor, 10-50mg/L as corrosion inhibitor, and 1000-2000mg/L as detergent. Usually, HEDP is used together with polycarboxylic acid.
