Name: 1-Hydroxy Ethylidene-1 1-Diphosphonic Acid Corrosion Inhibitor/ HEDP
CAS: 2809-21-4
Chemical formula: C2H8O7P2
Appearance: White crystalline powder
Hydroxyethylenediphosphonic acid (HEDP) is a new type of chlorine-free electroplating complexing agent, which is used as the main agent for water quality stability in circulating cooling water system and plays the role of corrosion inhibition and scale inhibition.
Main Applications:
HEDP is widely used in many industrial fields, including but not limited to:
1. Electric power, chemical industry, metallurgy, fertilizer and other industries: as scale and corrosion inhibitor for circulating cooling water system and medium and low pressure boiler, oil field water injection and oil pipeline.
2. Light textile industry: used as cleaning agent for metal and non-metal.
3. Bleaching and dyeing industry: as peroxide stabilizer and color-fixing agent.
4. Cyanide-free electroplating industry: as complexing agent.
5. Pharmaceutical industry: as a carrying agent for radioactive elements.
In addition, HEDP is also used in low-pressure boiler water treatment, circulating water treatment, industrial municipal clean water, metal corrosion inhibition for swimming pool sterilization.
