Performance and Usage
PBTC has a low phosphorus content, and due to its structural characteristics of phosphonic and carboxylic acids, it has good scale and corrosion inhibition performance, which is superior to commonly used organic phosphonic acids. Especially at high taperatures, its scale inhibition performance is far superior to commonly used organic phosphonic acids, which can improve the solubility of zinc, have good resistance to chlorine oxidation, and have good synergistic properties in compounding. It is widely used in the formulation of efficient scale and corrosion inhibitors, and is one of the best performing products. It is also an excellent stabilizer for zinc salts. PBTC is widely used for corrosion and scale inhibition in circulating cooling water systas and oilfield water injection systas, especially suitable for compounding with zinc salts and copolymers. It can be used in situations where high taperature, high hardness, high alkalinity, and high concentration factors are required for operation; It can be used as a chelating agent and metal cleaning agent in the washing industry.
