Difference between Polishing Resin and Ion Exchange Resin

　　Polishing resins are commonly used at the end of an ultra-pure water treatment (EDI) system to ensure that the quality of the system's effluent can maintain water standards. Generally, the effluent water quality can reach above 18 mega-ohms, and has certain control ability to TOC and SIO 2. Polishing resins are H and OH in ionic form. Polishing resins can only be used once and are not renewable. They are generally used in semiconductor industry.

　　Ion exchange resins: Ion exchange resins are polymer compounds with functional groups (active groups of exchange ions), network structure and insolubility. Ion exchange resin is divided into cation resin and anion exchange resin, electronic polishing resin, positive resin into H + type and Na + type, negative resin into OH - type and Cl - type. For softening and desalination treatment.

　　Non-regenerative polishing resin is also called nuclear polishing resin, high-purity water mixing bed resin, ultra-pure water polishing resin is generally used for post-refining after RO (EDI), nuclear polishing resin, ultra-pure water treatment system end, to ensure that the water quality of the system can maintain the water standard of high purity ion exchange resin. The ion forms of polishing resins are H and OH, which have been pre-mixed before leaving the factory. After filling, it can be used directly without regeneration. Generally, the effluent water quality can reach above 18 mega-ohms, especially for TOC and SIO 2.
