Product Details

What is Tannic Acid ?

Tannic acid is mainly used in medicine, ink, printing and dyeing, leather and metallurgy industries as well as water treatment. Tannin has flocculation, deoxidation, scale inhibition and bactericidal action in the water treatment process. Due to the large amount of hydroxyl groups in the molecular structure and the carboxyl groups generated after partial hydrolysis, complexes with calcium and magnesium ions in water prevent the formation of scale of calcium and magnesium ions in boiler water, and also reduce the deposition of calcium sulfate in cooling water. , to play a decentralized role. In addition, the cohesive force of tannins can concentrate the sediment into the slag and discharge the boiler and cooling water system through the sewage.
