PBTC has low phosphorus content, due to its structural properties of phosphonic acid and carboxylic acid, PBTC has good scale and corrosion inhibition performance, superior to commonly used organophosphonic acid, especially in high temperature scale inhibition performance is much better than commonly used organophosphonic acid, can improve the solubility of zinc, good resistance to chlorine oxidation, good synergistic compounding. It has a wide range of applications in the compounding of high efficient scale and corrosion inhibitors, with superior performance, and is also an excellent stabiliser for zinc salt.
Advantages of pbtc
Low phosphorus content: pbtca has low phosphorus content, which helps to reduce the impact on the environment.
Structural properties: Due to the structure containing phosphonic acid and carboxylic acid, PBTCA has excellent scale and corrosion inhibition performance, especially at high temperature, its scale inhibition performance is better than other commonly used organophosphonic acid .
Improvement of zinc solubility: PBTC can improve the solubility of zinc salts, which is helpful for the use of zinc salts in water treatment.
Resistance to chlorine oxidation: PBTC has good resistance to chlorine oxidation, which makes it stable under chlorinated water conditions.
Compounding synergy: PBTC and other water treatment agents such as zinc salts, copolymers, organophosphorus, azoles, etc. have a good synergistic effect when used in combination.
Wide application: PBTC is widely used in circulating cooling water system, oilfield water injection system and washing industry as chelating agent and metal cleaning agent.
Chemical stability: PBTC has good chemical stability, even in water up to 120 ℃ also shows good thermal stability and stability to hydrolysis.
