Diethylenetriamine pentamethylene phosphonate sodium is an organophosphorus series scale inhibitor. Its molecular formula is C9H28O15N3P5, and its relative molecular weight is 573.2. Diethylenetriamine pentamethylene phosphonate sodium is non-toxic, miscible with water, has better scale inhibition and corrosion inhibition effect, and has good temperature resistance, which can inhibit the formation of carbonate, sulfate and phosphate scale. Especially when the pH value is 10-11, calcium carbonate still has a good scale inhibition performance, and the scale inhibition effect at this time is 2 to 3 times higher than that of hydroxy-ethylenediphosphonic acid and amino trimethylenephosphonic acid. Another outstanding feature is that the combination with manganese ions has a good corrosion inhibition ability on carbon steel and copper alloys.
HPAA is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safety in use, no toxicity, no pollution. HPAA can improve zinc solubility. Its corrosion inhibition ability is 5-8 times better than that of HEDP and EDTMP. When built with low molecular polymers, its corrosion inhibition effect is even better. HPAA is mainly used as cathode corrosion inhibitor in oilfield refill water system in fields such as steel & iron, petrochemcal, power plant and medical industries. When built with zinc salt, the effect is even better.

Usage of HEDP: 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. Package and storage of HEDP: Hedp liquid: normally in 250kg net plastic drum, ibc drum can also be used as required hedp solid: 25kg inner liner polyethylene (pe) bag, outer plastic woven bag, or confirmed by clients.

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 metalsâ?? surfaces. Hedpshows excellent scale and corrosion inhibition effects under temperature 250â??. 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.
