Its antiscale property under high temperature is far better than that of organophosphines. It can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy. Specification: items index Appearance Colorless or light yellow transparent liquid Active acid % 49.0-51.0 Phosphorous acid(as PO33-)% 0.8 max Phosphorous acid(as PO43-)% 0.5 max Density (20℃) g/cm3 1.27 min pH(1% solution) 1.5~2.0 Usage: PTBCA is a high efficient agent as scale and corrosion inhibitor. It is the excellent stabilizer for zinc salt. It is widely used in circulating cool water system and oilfield refill water system as scale and corrosion inhibitor, suitable to composite with zinc salt and copolymer. It can be used in situations of high temperature, high hardness, high alkali and high concentration index. In lavation fields, it is used as chelating agent and metal detergent. PBTCA is usually used together with zinc salt, copolymer, organophosphine, imidazole and other Water Treatment Chemicals. When used alone, the dosage of 5-15mg/L is preferred. Package and Storage: Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for one year in room shady and dry place. Safety Protection: Acidity, Avoid contact with eye and skin, once contacted, flush with water.

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
