Specification: items index aqueous solution Active acid % 50.0-51.0 Phosphorous acid(as PO33-)% 0.5 max Phosphoric acid(as PO43-)% 0.2 max Density (20℃) g/cm3 1.27 min pH(1% water solution) 1.5~2.0 Fe ppm 10.0 max Chloride ppm 10.0 max Turbidity (NTU) 10.0 max Color APHA 30.0 max Usage: PBTCA is a high efficient agent as scale and corrosion inhibitor. PBTCA 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. PBTCA 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.
