What is the anion exchange resin in PVC membrane?

The anion exchange resin ion exchange method in PVC membrane is a reversible chemical reaction between the ions in the liquid phase and the ions in the solid phase. When some ions in the liquid phase are more preferred by ion exchange solids, it will To be absorbed by the ion exchange solid, in order to maintain the neutrality of the aqueous solution, the ion exchange solid must release equivalent ions back into the solution.

Ion exchange resin contains a certain amount of water and should not be stored in the open air. During storage and transportation, it should be kept moist to avoid dehydration and breakage of the resin. If the resin is dehydrated during storage, it should be soaked in concentrated brine (25%) first, and then gradually Dilution, do not put it directly into water, so as to avoid the resin from swelling and breaking.
