Introduction To The Decolorization Of Resin

Jul 23, 2020

resin, there are two types of natural and synthetic, has the functions of purifying water, decoloring, adsorption, softening, etc., here we first understand how decolorizing resin is.

   decolorizing resins are generally divided into two types, namely ion exchange resins and macroporous adsorption resins. The ion exchange resin achieves the decolorization effect through ion exchange, and the macroporous adsorption resin achieves the decolorization effect through the adsorption of specific surface area and mesh pore volume.

"For example, starch sugar discoloration can be decolorized with D354FD macroporous weak base resin, and the end can also be refined with SD300 to remove impurities and odors. You can also choose macroporous strong alkali anion resin for decolorization.

   Ion exchange resin is decolorized. In addition to ion exchange performance, ion exchange resin also has a good decolorization effect. Decolorization is essentially the use of charge adsorption of fixed ions in the resin. Since most pigments are anionic or weakly polar substances, ion exchange resins can be used to absorb macroporous ion exchange resins. It has a strong decolorization effect. It can be used as an excellent decolorizing agent for the decolorization of glucose, sucrose, and beet sugar. . Compared with activated carbon, ion exchange resin decolorization has the advantages of repeated use, long service life, convenient use, and less product loss.

   Therefore, the decolorization effect of resin is widely used in many industries to carry out the safe treatment of decolorization to ensure the effect.
