Description

Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP)HEDP  Manufacturers, China HEDP Suppliers, China HEDP Exporters manufactures and supplies HEDP Chelation,iron chelation agent, Sequestering Agent. HEDP Chelation, iron chelation agent, sequestering agents HEDP Chelation / Sequestering Agent, CAS No.:: 2809-21-4  Another name: Dequest 2010 Molecular Formula: C2H8O7P2                   Molecular weight: 206.02  Structural Formula:    Product performance:  HEDP is an organic phosphonic acid corrosion inhibitor, can form into stable complex compound through chelating with Fe?copper?zinc and other metal ions, and can dissolve the oxides on the metals’ surfaces. It can play a good role at scale and corrosion inhibition under 250?, is also stable under high PH value, not easily to be dissolved and not easily to be resolved under thermal condition. When it is used complex together with other water treatment chemicals, will express ideal synergistic effect. Specification:  Item Index Appearance Colorless or light yellow clear liquid Active content (HEDP)%= 50.0 60.0 Phosphorous acid (as PO33-)%= 2.0  0.5  Phosphonic acid  (asPO43- )%= 0.8 0.8  Chloride (as Cl-)%= 1  1  PH value (1% water solution) 2 2 Density  (20?) g/cm3= 1.34 1.40 Calcium chelate value mg/g= 450 500 Range of application: HEDP is widespread used as scale and corrosion inhibition in industrial circulating cooling water systems?low-pressure boilers?oilfield water injection?pipe laying at the field of electron?chemical industry?metallurgy?fertilizer and so on. In light textile industry, it can be used as metal and nonmetallic’s cleaning agent, peroxide’s stabilizer and color fixing agent in dyeing industry, chelating agent in non-cyanide electroplating. 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 is used together with polycarboxylic acid dirt dispersion agent.  Usage: 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 is used together with polycarboxylic acid dirt dispersion agent.  Package and Storage: Normally In 30kg or 250kg net Plastic Drum, IBC drum can also be used as required. Storage for ten months in room shady and dry place.
