Application:
1. HEDP (2809-21 4) is used as scale and corrosion inhibition 
in circulating cool water system, oil field and lowpressure boilers 
in fields such as electric powe, chemical industry, metallurgy, 
fertilizer, etc..
2. In light woven industry,HEDP (2809-21-4) is used as detergent 
for metal and nonmetal.
3. In dyeing industry, HEDP (2809-21-4) is used as peroxide 
stabilizer and dye-fixing agent.
4. In non-cyanide electroplating, HEDP (2809-21-4) 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 (2809-21-4) is used 
together with polycarboxylic acid.
