Fluorine-containing cation exchange membrane for electrolysis. |
摘要 |
<p>A fluorine-containing cation exchange membrane for electrolysis, which comprises a first layer of a fluorine-containing polymer having cation exchange groups and reinforced with a porous base material and a second layer of a fluorine-containing polymer having carboxylic acid groups, present on the cathode side of the first layer, wherein at least 1/2 of the thickness of the porous base material protrudes from the first layer towards the anode side, the protrusions of the porous base material are covered with a coating layer of a fluorine-containing polymer having cation exchange groups so that the coating layer is integrated or united with the first layer, and the anode side surface of the coating layer has a roughness corresponding to the surface contour of the porous base material.</p> |
