Hydroxyethylidene diphosphonic acid (HEDP) is a new type of chlorine-free electroplating complexing agent. It is used as the main agent for water quality stabilization in the circulating cooling water system and plays a role in corrosion and scale inhibition. This product is one of the organic polyphosphonic acid water treatment agents. There are some other varieties of this type of products produced in China, such as aminotrimethylenephosphonic acid (ATMP): [CH2PO(OH)2]3N and ethylenediaminetetramethylenephosphonic acid (EDTMP), etc. Organic polyphosphonic acid is a type of water treatment agent developed in the late 1960s and confirmed around the 1970s. The emergence of this type of treatment agent has made a big step forward in water treatment technology. Compared with organic polyphosphates, organic polyphosphonic acid has the characteristics of good chemical stability, not easy to hydrolyze, high temperature resistance, small dosage, and corrosion mitigation performance. It is a type of cathodic corrosion inhibitor and a type of non-chemical equivalent scale inhibitor; when used in combination with other water treatment agents, it shows an ideal synergistic effect. It has excellent chelating ability for many metal ions such as calcium, magnesium, copper, zinc, etc., and even has a good deactivation effect on inorganic salts of these metals such as CaSO4, CaCO3, MgSiO3, etc., so it is widely used in water treatment technology.
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 HEDP shows excellent scale and corrosion inhibition effects under temperatures of 250C HEDP has good chemical stability under high pH values is hard to hydrolyze and is hard to decompose under ordinary light and heat conditions Its acidalkali and chlo rine oxidation tolerance are better than that of other organophosphoric acids salt HEDP can react with metal ions in the water system to form a hexaelement chelating complex with calcium ions in particular Therefore HEDP has good antiscale and visible threshold effects When built together with other water treatment chemicals it shows good synergistic effects Application HEDP is used as scale and corrosion inhibition in circulating cool water system oil field and lowpressure 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 dyefixing agent In noncyanide electroplating HEDP is used as chelating agent The dosage of 110mgL is preferred as scale inhibitor 1050mgL as corrosion inhibitor and 10002000mgL as detergent Usually HEDP is used together with polycarboxylic acid
