This product is a type of strong alkaline type II gel-type anion exchange resin which is consisted by the styrene divinylbenzene copolymer crosslinking structure has a polymer matrix with quaternary amine group. It has properties like high exchange capacity,easy regeneration, low alkali cost during the regeneration,strong anti-penetration performance,high regeneration rate and others.Alkaline of the product is equivalent to that of ordinary quaternary amine hydroxide.This type of product presents ion exchange functions in acidic, neutral,even alkaline medium.However,it has good physical and chemical stability as well as strong resistance of penetration,abrasion and stain.Cooperated with weak alkaline anion resin,this strong slkaline resin can be applied for pure water and ultra-pure water preparation in anion bunk resin bed system
