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℃. 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 (20℃) 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 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 250kg net Plastic Drum, IBC drum can also be used as required. Storage for ten months in room shady and dry place.

Company Information (Shandong Taihe Water Treatment Co. Ltd)

Company Profile: Shandong TAIHE water treatment Co., Ltd. (former Zaozhuang TAIHE chemical factory) is located in Zaozhuang city, south of Shandong province. The company was founded in 1998. It is one of the largest and professional water treatment chemicals factory in China, can manufacture all kinds of water treatment chemicals. The total yields reach to over 20,000 tons now. The product families include antiscalant, corrosion inhibitors, biocide agents, cleaning agents, pretreatment filming agents, chelating agents, dispersants, RO membrane chemicals and etc., covering wide ranges from single to complex agents. The products are widely used in industrial circulating water system, boiler and heating water system. To satisfy the need of different fields, some solid products such as organophosphoric acids and their sodium salts are developed recently in our factory, including high pure grade and ordinary grade. Some polymer solid products have also been developed. To cooperate with our clients for water quality analysis and treatment process planning, we have set up a synthesis and application laboratory, several research projects are done in this laboratory.. >> More Website URL: http://www.bridgat.com/u115
