          Ethylene Diamine Tetra (Methylene Phosphonic Acid) SodiumI(EDTMPS)

          Ethylene Diamine Tetra (Methylene Phosphonic Acid) SodiumI(EDTMPS)

          【CAS】1429-50-1

          Molecular Formula:  C6H12O12N2P4Na8C         Molecular weight: 612.13

          1, Properties

          EDTMPS is nitrogenous organic polyphosphonic acid, a part of cathodic corrosion inhibitor. Its corrosion inhibition is 3~5 times better than that of inorganic polyphosphate. It is miscible with water, innocuous and none pollution to environment, has good chemical stability and temperature tolerance. It shows excellent scale inhibition ability under temperature 200℃. It can dissociate into 8 positive-negative ions, thus can chelate with many metal ions to form polymer reticulation complex, to destroy the normal crystallization of calcium scale. EDTMPS shows better antiscale effects to calcium sulfate and barium.

          2, Specification:

           3,Application range&using method

          EDTMPS can be used as corrosion inhibitor in circulating cool water system and boiler water. It is a chelating agent in non-cyanogen electroplating industry and a water-softening agent in printing & dyeing industry. When used alone, 2~10mg/L is preferred. When built with HPMA by ratio ETDMP:HPMA=1:3, it can be used for low pressure boiler. It can also be built with BTA, PAAS and zinc salt.  Organic phosphonic acid

          4,Package and Storage:

          Normally EDTMPS packed with 25kg net Plastic Drum, or packed as customer’s required. Storage for ten months in room shady and dry place.
