Professional Perfluorinated Ion-Exchange Membrane(PIEM) and Homogeneous Ion-Exchange Membrane manufacturer in China


Ion exchange membranes are membranes that enable ions to pass selectively. They can be divided into cation exchange membranes and anion exchange membranes. In cation exchange membranes, there are fixed negative charged functional groups, so anions can not pass through in solution because of their repulsion,only cations can be used. Anion exchange membranes can selectively pass anions by using the opposite action. The selectivity of ion exchange membranes is achieved by DC electric field force of electrodialysis.

Characteristics of Ion Exchange Membrane


1. High ion selective permeability
Commonly used expression of counter ion mobility or membrane transmittance, JCM, JAM series ions The selectivity of exchange membranes to counter ions is over 90%, and the permeability of ions with the same charge is low.
2. High switching capacity and low surface resistance
Homogeneous membranes prepared by immersion method have thin thickness, no adhesives and supporting materials, high charge density of functional groups, strong conductivity and much lower power consumption than heterogeneous ion exchange membranes. Membrane resistance is the main factor that decides the operation cost of the project.
3. High acid and alkali resistance, good chemical and physical structure stability
Membrane materials are made of acid-and alkali-resistant macromolecule materials. The tolerance of acid and alkali reaches 6 moL at room temperature. The interface is bonded by covalent bonds, and the structure is stable for a long time. There is no stratification or bubbling in use.
