UseThe phosphorus content of PBTCA • Na4 is low. Because it has the structural characteristics of phosphonic acid and carboxylic acid, it has good scale inhibition and corrosion inhibition performance, which is superior to the commonly used organic phosphonic acid, especially at high temperature, the scale inhibition performance is far better than that of the commonly used organic phosphonic acid, which can improve the solubility of zinc, the oxidation resistance of chlorine is good, and the compound is good. The solid is easy to absorb moisture.

2-Phosphonobutane -1,2,4-Tricarboxylic Acid, Sodium sal - Reference Information

EPA chemical information Information provided by: ofmpub.epa.gov (external link)
product performance PBTCA · Na4 has low phosphorus content. due to its structural characteristics of phosphonic acid and carboxylic acid, it has good scale inhibition and corrosion inhibition performance, which is superior to commonly used organic phosphonic acid, especially its scale inhibition performance at high temperature is far superior to commonly used organic phosphonic acid, which can improve the solubility of zinc, has good chlorine resistance and good compound coordination. Solid is easy to absorb moisture.
usage PBTCA · Na4 is the most widely used in high-efficiency scale and corrosion inhibitor compounding, is one of the products with the best performance, and is also an excellent stabilizer for zinc salt. PBTCA.Na4 is widely used in the corrosion and scale inhibition of circulating cooling water systems and oil field water injection systems. It is especially suitable for the compound use of zinc salts and copolymers. It can be used for high temperature, high hardness, high alkali, and high concentration ratios. It is used as a chelating agent and metal cleaner in the washing industry.
