Molecular formula: c7h7o9p · Na4 relative molecular mass: 358

1、 Performance and Application

PBTCA · Na4 has low phosphorus content. Due to its structural characteristics of phosphonic acid and carboxylic acid, it has good scale and corrosion inhibition performance, which is better than the commonly used organic phosphonic acid. Especially at high temperature, the scale inhibition performance is much better than the commonly used organic phosphonic acid, which can improve the solubility of zinc, good chlorine oxidation resistance and good compound synergy. PBTCA · Na4 is the most widely used in the combination of high-efficiency scale and corrosion inhibitors. It is one of the products with the best performance and an excellent stabilizer of zinc salt. PBTCA ・ Na4 is widely used in corrosion and scale inhibition of circulating cooling water system and oilfield water injection system. It is especially suitable for compounding with zinc salt and copolymer. It can be used in occasions with high temperature, high hardness, high alkali and high concentration multiple. It can be used as chelating agent and metal cleaning agent in washing industry.
