Product Description

Properties of HEDP (Cas No 2809-21-4) Corrosion Inhibitor:

HEDP (Cas No 2809-21-4) Corrosion Inhibitor is an organophosphoric acid corrosion inhibitor. It can chelate with Fe, Cu, and Znions to form stable chelating compounds. It can dissolve the oxidized materials on these metals'' surfaces. HEDP (Cas No 2809-21-4) Corrosion Inhibitor shows excellent scale and corrosion inhibition effects under temperature 250°C. HEDP (Cas No 2809-21-4) Corrosion Inhibitor has good chemical stability under high PH value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. Its acid/alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids (salt). HEDP (Cas No 2809-21-4) Corrosion Inhibitor can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP (Cas No 2809-21-4) Corrosion Inhibitor has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects.

Specification of HEDP (Cas No 2809-21-4) Corrosion Inhibitor:

As below:

Active Content (HEDP)%	58.0-62.0
Phosphorous Acid (as PO33-)%	1.0 Max
Phosphoric Acid (asPO43- )%	0.5 Max
Chloride (as Cl-)%	0.3 Max
PH (1% Solution)	2 Max
Density (20°C)g/cM3	1.40 Min

Usage of HEDP (Cas No 2809-21-4) Corrosion Inhibitor:

1. HEDP (Cas No 2809-21-4) Corrosion Inhibitor is used as scale and corrosion inhibition in circulatingcool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. 2. In light woven industry, HEDP (Cas No 2809-21-4) Corrosion Inhibitor is used as detergent for metal and nonmetal. 3. In dyeing industry, HEDP (Cas No 2809-21-4) Corrosion Inhibitor is used as peroxide stabilizer and dye-fixing agent. 4. In non-cyanide electroplating, HEDP (Cas No 2809-21-4) Corrosion Inhibitor 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 (Cas No 2809-21-4) Corrosion Inhibitor is used together with polycarboxylic acid.

Package and Storage of HEDP (Cas No 2809-21-4) Corrosion Inhibitor:

HEDP (Cas No 2809-21-4) Corrosion Inhibitor: Normally in 250kg net Plastic Drum, IBC Drum can also be used as required. Storage for ten months in shady room and dry place.
