PBTC can improve the solubility of zinc, and has good chlorine oxidation tolerance and good composite synergy.
PBTC is most widely used in the combination of high-efficiency scale and corrosion inhibitors, as one of the best chemicals, and it is also an excellent stabilizer of zinc salt. PBTC is widely used as corrosion and scale inhibitors in the circulating cooling water system and oilfield water injection systems and is especially suitable for use with zinc salt and copolymer. It can be used in the situation of high temperature, high hardness, high alkali and high concentration times. PBTC can be used as a chelating agent and metal cleaning agent in the washing industry.
PBTC 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.
