The full name of PBTCA is butane-2-phosphonate-1,2,4-tricarboxylic acid, and its appearance is generally colorless to light yellow transparent liquid. PBTCA has a lower phosphorus content, but due to its structural properties of both phosphonic and carboxylic acids, it performs well in scale inhibition and corrosion inhibition, even better than some commonly used organic phosphonic acids. Especially in the high-temperature environment, its scale inhibition performance is far better than that of conventional organic phosphonic acid, which can effectively improve the solubility of zinc. In addition, it also has good resistance to chlorine oxidation, and has a good synergistic effect with other water treatment agents.
Among the many high-efficiency scale and corrosion inhibitors, PBTCA has a wide range of applications, superior performance, and is also a good stabilizer for zinc salts. It is widely used in corrosion and scale inhibition in circulating cooling water systems and oilfield water injection systems, especially in combination with other water treatment agents such as zinc salts and copolymers. PBTCA is suitable for high temperature, high hardness, high alkali and high concentration factor operation, and provides strong support for industrial water treatment.
In the laundry industry, PBTCA is used as a chelating agent and metal cleaning agent. In order to achieve the best results, it is usually compounded with other water treatment agents such as zinc salts, copolymers, organophosphorus, azoles, etc. When used alone, the dosing dose is usually 5-15 mg l.
In terms of packaging, PBTCA uses plastic drums with a capacity of 25kg or 250kg per drum. It should be stored in a cool place indoors for 12 months. However, it should be noted that PBTCA is an acidic substance, and labor protection should be strengthened during operation, and contact with **, eyes and other parts should be avoided. In case of accidental contact, rinse immediately with plenty of water.
