Use: Widely used in circulating cooling water system and oilfield water injection system for corrosion and scale inhibition, especially suitable for compounding with zinc salt and copolymer, can be used in high temperature, high hardness, high alkali and need high concentration times under the operation of the occasion, PBTCA in the washing industry can be used as chelating agent and metal cleaning agent. It can be added to cooling water after compounding with zinc salts to improve the corrosion inhibition performance and scale inhibition ability in alkaem, the general dosage is 5-15ppm, continuous dosage is appropriate..Contact us by text,call, what's app ; or
