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

Perfluorinated Ion-Exchange Membrane for  Electrolysis

Cation exchange membranes are selective membranes of cations, usually sulfonic acid type, with immobilised groups and cleavable ions. For example, the sodium-type sulfonic acid-type immobilisation group is sulfonate, and the dissociation ion is sodium ion. . The cation exchange membrane can be regarded as a kind of polymer electrolyte. Since the positive membrane is negatively charged, although the original dissociated positive ion is dissociated into the water by the action of water molecules, it is energized by the electric field outside the membrane and is positively charged. The cations can pass through the positive film, while the anions cannot pass because of homosexual rejection, so they have selective permeability.
The perfluorinated cation exchange membranes are produced with the new casting method, the casting process can be combined with doping technology,we add new fluororesin mixing formula with good vanadium resistance in the casting process, the Ion-Exchange Membrane has high tensile strength, isotropic, high electrical conductivity, good chemical properties, and so on.
