What is scale inhibitor chemicals?

Scale inhibitors are chemical water treatment agents that play an important role in the daily treatment of circulating water. Their main component is phosphate, with trisodium phosphate being the most commonly used. These inhibitors typically react with metal surfaces in the pipes to form a metal film called a "pre-film,"

Scale inhibitors are chemical water treatment agents that play an important role in the daily treatment of circulating water. Their main component is phosphate, with trisodium phosphate being the most commonly used. These inhibitors typically react with metal surfaces in the pipes to form a metal film called a "pre-film," which effectively protects the metal surface from the impact of waterborne deposits.

The working principle of Kaidefei polyphosphate scale inhibitor involves reacting with calcium (Ca) and magnesium (Mg) ions in the water to form soluble complexes, keeping them stable under heating conditions and preventing the precipitation of calcium and magnesium ions, thereby inhibiting scale formation. The scale inhibitor also forms a thin protective film on the metal surface, isolating the metal from contact with oxygen in the water, thereby suppressing corrosion. This dual action not only controls corrosion but also prevents scaling.
