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

Description

Product code : CAS No. ********1 Molecular Formula: C6H*2O*2N2P4Na8 Molecular weight: **2.*3 Properties: EDTMPS is nitrogenous organic polyphosphonic acid, a part of cathodic corrosion ***** 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 **0℃. 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: 1. Appearance ï&frac*4;šClear yellow to umber transparent liquid 2. Active component (EDTMPS)% *0.0min 3. Organic phosphonic acid (asPO**- )% *0.0min 4. Phosphorous acid (as PO**-)% 5.0max 5. Phosphoric acid (asPO**- )% 1.0max 6. pH (1% water solution) 9.***0.5 7. Density (*0℃) g/cm 3 1.*5min 8. 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~*0mg/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. Package and Storage:Normally In **0kg net Plastic Drum, IBC drum can also be used as required. Storage for ten months in room shady and dry place.
