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 200C. 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. Specification: items index Appearance Clear yellow to umber transparent liquid Active component (EDTMPS)% 30.0min Organic phosphonic acid (asPO43- )% 10.0min Phosphorous acid (as PO33-)% 5.0max Phosphoric acid (asPO43- )% 1.0max pH (1% water solution) 9.5-10.5 Density (20C) g/cm3 1.25min Chloride (as Cl-)% 3.0max Usage: 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 EDTMP:HPMA=1:3, it can be used for low pressure boiler. It can also be built with BTA, PAAS and zinc salt. Package and Storage: Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for ten months in room shady and dry place.
