Usage:
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.
plastic drum.
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 temperature 250¡æ. 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 ar 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.
