Application:
Water Treatment: HEDP is widely used in industrial circulating cooling water systems, boiler water, oilfield water injection, and pipeline corrosion protection for oil transportation. It effectively controls the deposition of water scales such as calcium carbonate and calcium sulfate formed by calcium and magnesium ions.
Industrial Cleaning: As an efficient cleaning agent, HEDP can be used for cleaning metal and non-metal surfaces, preventing damage to metal surfaces caused by corrosion.
Textile Printing and Dyeing: In the textile industry, HEDP serves as a bleach stabilizer and color fixative, enhancing the stability of bleaching processes and improving colorfastness of dyed fabrics.
