强碱阴离子交换树脂 201x7（717）FC/SC（ anion exchange resin 201X7 (717) FC/SC）
Ion exchange resin is a kind of insoluble polymer with functional groups, and its structure is composed of three parts, which are polymer skeleton, ion exchange group and hole. Ion exchange resin can be through the exchange of the ion exchange and adsorption, to achieve separation, replacement, purification, concentration, enrichment and other effects.

Ion exchange resin is the most important and valuable properties, the reversibility of the reaction ion exchange, resin after the application of failure, acid, alkali or other regeneration agent for regeneration, restore its ability to exchange, the ion exchange resin can be used repeatedly for a long time.
