HEDP TW (MQ1500)

• 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.

• 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℃.
• 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.
