【Application】HEDP Metallic And Nonmetallic Cleaning Agents Chilled Water Treatment Chemicals
1. HEDP is widely used in electric power, chemical, metallurgy, fertilizer and other industrial circulating cooling
water system and middle and low pressure boiler, oilfield water injection and oil pipeline scale and corrosion
inhibition;
2. In light textile industry, it can be used as cleaning agent for metal and non-metal, peroxide stabilizer and color
fixing agent for bleaching and dyeing industry, complexing agent for cyanide-free electroplating industry, and
carrier for radioactive elements in pharmaceutical industry.
HEDP is generally used as scale inhibitor at a concentration of 1 ~ 10mg/L, and corrosion inhibitor at a concentration
of 10-50mg/L.
Generally used as cleaning agent concentration of 1000 ~ 2000mg/L;
Usually used in conjunction with polycarboxylic acid scale inhibitor dispersants.
When used in other industries, the dosage should be determined according to the test.
