Uses:

Hydroxyethylidene diphosphonic acid, also known as HEDP, is a diphosphate compound used in dish soap, water purification processes, cosmetics and pharmaceutical production.

 

This product has good scale and corrosion inhibition effects, and has the characteristics of high temperature resistance, good oxidation resistance, low toxicity, etc. It is mainly used for scale and corrosion inhibition of industrial circulating cooling water. A variety of metal ions and other metal ions form stable complexes, so it can be used to clean rust and inorganic salt scale in boilers and pipelines.
