SCALE & CORROSION INHIBITORS 1-Hydroxyethylidene-1,1-diphosphonic acid / HEDP 90%-HOOCHEMTEC
1-Hydroxyethylidene-1,1-diphosphonic acid / HEDP
CAS No. : 2809-21-4
Appearance: White crystal powder, Colorless to pale yellow aqueous solution
Type: 90% crystal powder and 60% liquid
Properties
HEDPis an organophosphoric acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn etc. metal ions and form stable complex compound. It can dissolve the oxidized materials on these metals’ surfaces. Under 250℃HEDP shows excellent scale and corrosion inhibition ability.
HEDPhas good chemical stability under high pH value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions.
HEDPcan react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects.
HEDPsolid is high purity product, suitable for using in winter and freezing districts. it is quite suitable for using as cleaning agent in electronic fields and as additives in daily chemicals.
Applications
- is used as scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc..
- In light woven industry,is used as detergent for metal and nonmetal.
- In dyeing industry,is used as peroxide stabilizer and dye-fixing agent;
- In non-cyanide electroplating,is used as chelating agent.
