Performance and use
PBTC has low phosphorus content, due to its structural characteristics of phosphonic acid and carboxylic acid, so that it has good scale inhibition and corrosion inhibition performance, better than commonly used organic phosphonic acid, especially at high temperature scale inhibition performance is much better than commonly used organic phosphonic acid, can improve the solubility of zinc, good oxidation resistance to chlorine, good coordination.

PBTC is widely used in the compound of high efficiency corrosion and scale inhibitors, with excellent performance, and is also an excellent stabilizer of zinc salt. Widely used in circulating cooling water system and oilfield water injection system corrosion and scale inhibition, especially suitable for use with zinc salt, copolymer, can be used in high temperature, high hardness, high alkali and need to operate under high concentration occasions, PBTC can be used as a chelating agent and metal cleaning agent in the washing industry.
