Superiority
HEDP is an organic phosphate scale inhibitor that forms stable complexes with various metal ions such as iron, copper and zinc, and dissolves oxides on metal surfaces. HEDP can still play a good role in corrosion inhibition and scale inhibition at 250 ° C. It is stable at high pH and is not easy to be hydrolyzed. It is not easy to decompose under normal photothermal conditions. Acid and alkali resistance and chlorine oxidation resistance are better than other organic phosphoric acid (salt). HEDP can form a six-ring chelate with metal ions in water, especially calcium ions. Therefore, HEDP has good scale inhibition effect and obvious solubility limit effect. It is ideal when used in combination with other water treatment agents. Synergistic effect.
HEDP solids are high-purity products suitable for use in cold winters; especially for cleaning agents and household chemicals in the electronics industry.
Details
HEDPis 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,HEDPis used as detergent for metal and nonmetal. In dyeing industry,HEDPis used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating,HEDPis 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,HEDPis used together with polycarboxylic acid.
