PBTCA, also known as 2-phosphosuccinic acid, is a chelating agent commonly used in industries such as water treatment, metallurgy, textiles, and leather. Its main functions are as follows:
Scale prevention: PBTCA can combine with metal ions such as calcium, magnesium, and iron in water to form stable complexes, thereby preventing their precipitation and scaling. In water treatment, PBTCA is commonly used to prevent the deposition of calcium and magnesium scales in hot water equipment.
Cannibalization: PBTCA can also dissolve or cannibalize already formed scale or rust, making it soft and easy to remove.
Corrosion inhibition: PBTCA also has good corrosion inhibition performance, which can inhibit the oxidation reaction of metals in water, reduce or delay the corrosion of pipelines and equipment.
Stability: PBTCA can stabilize oxidants and bleaches to a certain extent, preventing their premature decomposition or failure.
Overall, PBTCA is a multifunctional chelating agent that can enhance the anti scale, corrosion, and stability performance of water treatment agents, extend the service life of equipment, and has a wide range of applications in industrial production.
