ABSTRACT:
The gasket is disposed between the electrode frames, which are pressed against each other and are used in a membrane electrolysis for producing sodium solution, hydrogen and chlorine from an NaCl brine. The rim of the membrane is disposed between two parts of the gasket. At least one gasket part consists of a core frame, which is provided at least on one side with an attached sealing frame made of graphite. The core frame and the sealing frame are enclosed in a plastic film wrapper. The core frame may be made of asbestos and the plastic film wrapper may be made of polytetrafluoroethylene.
