Product Description

Tannic acid is a polyphenol, also known as acid tannin or gallic acid. Tannic acid contains many phenolic groups and is therefore a weak acid. Naturally derived from bean pods, cork oak, Sicilian lacquer leaves. The chemical formula for tannic acid is C76H52O46. The two main types of tannins are condensed and hydrolyzed tannins.

1.Mainly used in medicine, ink, printing and dyeing, leather and metallurgy industries and water treatment. Tannin has the functions of flocculation, deoxidation, scale inhibition and sterilization in the water treatment process. Because there are a large number of hydroxyl groups and carboxyl groups produced by partial hydrolysis in the molecular structure, it forms complexes with calcium and magnesium ions in the water to prevent calcium and magnesium ions in the boiler water from forming scale, and can also reduce the deposition of calcium sulfate in the cooling water. , Play a decentralized role. In addition, the cohesive force of tannins can aggregate the sediment into slag, which is discharged out of the boiler and cooling water system through sewage.
2. It can be used as a clarifying agent for low-alcohol wine and fruit wine. It can also be used as a leather tanning agent.
3. Tannic acid is used for chromium-free passivation of galvanized layer.
