Monosodium Of 1-Hydroxy Ethylidene-1,1-Diphosphonic Aci (HEDP.Na)
Description

Monosodium Of 1-Hydroxy Ethylidene-1,1-Diphosphonic Aci(HEDP.Na)

CAS No. 29329-71-3

Molecular Formula: C2H7O7P2Na                              Molecular Weight: 228

Structure:

            Monosodium Of 1-Hydroxy Ethylidene-1,1-Diphosphonic Aci (HEDP.Na)

1. Properties:

HEDP.Na is an organic phosphonic acid corrosion inhibitor, with iron, copper, zinc and other metal ions to form stable complexes, can dissolve the metal surfaces.At250℃ can still play the role of a good scale and corrosion inhibitor, remains stable under high pH, hard to be hydrolyzed, usually difficult to decompose under the conditions of light and heat. Acid and alkali resistance, resistance to chlorine oxidation are better than other organic acids (salt).

HEDP.Na can react with metal ions in water system to form hexa-element chelating complex with calcium ion in particular. Therefore, it has good antiscale and visible threshold effects.When built together with other water treatment chemicals, it shows good synergistic effects.

HEDP.Na is most suitable for scale inhibition agents and acid detergent formulations, HEDP.Na is a cross-hydroxy-B-diphosphonic acid monosodium salt, for metal cleaning, metal processing and metal ion control and other applications. HEDP.Na widely used in electric power, chemical, metallurgy, fertilizer and other industrial cooling water system and the low pressure boiler, oil field water injection and oil pipeline scale and corrosion inhibition; HEDP.Na in the textile industry, can be used for metal and non- metal cleaning agent, bleaching and dyeing industry peroxide stabilizer and dye-fixing agent, non-cyanide electroplating industry complexing agent.

2. Using method:

As scale inhibitor general use density 2~20mg / L, as corrosion inhibitor, 20-100 mg / L, as cleaning agent , general concentration is 1000~2000mg / L, usually with polycarboxylic acid scale inhibition and dispersion agent used in conjunction.

3. Package and Storage:

Normally In 30kg or 250kg net Plastic Drum, also be used as required.

Storage for ten months in room shady and dry place.

4. Safety Protection:

HEDP.Na is acidic, Avoid contact with eye and skin, once contacted, flush with water.
