The Homogeneous and Heterogeneous Cation Ion-Exchange Membrane manufacturer in China

Homogeneous cation exchange membrane

The cation exchange membranes are membranes that have a selective effect on cations. They are usually sulfonic, with fixed groups and dissociable ions. For example, sodium-type sulfonic-type fixed groups are sulfonate and dissociated ions are sodium ions. The cation exchange membrane can be regarded as a kind of polymer electrolyte. Because the positive membrane is negatively charged, although the original dissociated positive ions are dissociated into the water by the action of water molecules, electricity is applied to the outside of the membrane through the action of an electric field. The cation can pass through the cation membrane, while the anion cannot pass through because of the same-sex repulsion, so it has selective permeability.

Characteristics of Ion Exchange Membrane

  • 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.
  • 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.
