HEDP is a cost effective scale inhibitor used in various industrial applications such as industrial water treatment and detergents. It further shows good stability in presence of chlorine as well as corrosion inhibition properties in presence of zinc and other phosphates. HEDP can be also used as chelating agent in the textile industry.


Applications:

Cooling water systems / industrial water treatment

Industrial detergents

Swimming pools

Metal surface treatment as corrosion inhibitor for steel

Stabilizer in H2O2 solutions

Sequestering agent in textile auxiliaries


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.
