Proton Exchange Membrane Strength Type

Ion exchange membrane is a kind of polymer membrane with ionic group and selective permeability to ions in solution. It is also called ion selective permeable membrane. [1] the ion exchange membrane can be divided into cation exchange membrane, anion exchange membrane and amphoteric exchange membrane according to their function and structure. Inlay ion exchange membrane, polyelectrolyte complex membrane five types. The structure of ion-exchange membrane is the same as that of ion-exchange resin, but it is in the form of membrane. According to the structure of the membrane (or according to the manufacturing process), the ion-exchange membrane can be divided into three kinds: heterogeneous membrane, homogenous membrane and semi-homogeneous membrane. Both homogeneous and heterogeneous membranes can be dehydrated and brittle or ruptured in the air, so they must be preserved in water.

Ion exchange membrane is not only used for desalination of seawater and brackish water to prepare drinking water, but also used as diaphragm for electrolysis equipment. Ion exchange membrane is the key component of electrodialysis equipment and electrolytic equipment.
