Edtmps

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 can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal tolerance. It shows excellent scale inhibition ability under temperature 200 centigrade.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 sulfate.

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. Normally In 250kg net Plastic Drum, IBC drum can also be used as required.

Edtmps Ethylene diamine tetra (methylene phosphonic acid) sodium (edtmps, zf113) [cas no.] 1429-50-1 dequest: 2040 Molecular formula: c6h12o12n2p4na8 molecular weight: 612.13 Structural formula: Properties: This product is nitrogenous organic polyphosphonic acid, which is a part of cathodic corrosion inhibitor, its property is 3~5 times better than that of inorganic polyphosphate. It can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal resistance. It shows excellent scale inhibition property under temperature 200gs? it can dissociate into 8 positive-negative ions, thus can chelate with more than two metal ions to form more than two polymer reticulation complex, the complex can be quickly dissolved in water to destroy the normal crystallization of calcium scale. Edtmps shows better antiscale effects to calcium sulfate and barium sulfate. Specification: meet criterion of hg/t 3538-2003 Items Index Appearance Clear yellow to umber transparent viscous liquid Package and storage: 25kg in plastic barrel, or confirmed by clients. Storage for ten months in room shady and dry place.

Properties: EDTMPS is brown yellow transparent liquid. It has good chemical stability and has excellent scale inhibition effect for calcium carbonate and calcium sulfate under 200 degrees. At the same time, it has good dispersion and corrosion inhibition performance. Usage: As the scale inhibitor in circulation chilled water and boiler water and is also used as a complexing agent or water softener in other industrial water.
