Process for forming a diaphragm for use in an electrolytic cell
Abstract
Abstract AN IMPROVEMENT IN THE OPERATION OF AN ELECTROLYTIC CELL HAVING A DIAPHRAGM POSITIONED BETWEEN AN ANODE AND A CATHODE OF THE CELL IS PROVIDED BY EMPLOYING A DIAPHRAGM COMPRISING AN ASBESTOS MATRIX IMPREGNATED WITH AT LEAST ONE OF A GROUP OF POLYMERS INCLUDING SYNTHETIC RUBBERS AND THERMOPLASTIC AND THERMOSETTING POLYMERS AND COPOLYMERS. A CONTROLLED AMOUNT OF THE POLYMERIC IMPREGNANT IS DEPOSITED IN THE SPACES BETWEEN THE ASBESTOS FIBERS TO PROVIDE CONTROLLED AND REPRODUCIBLE PERMEABILITY AND DENSITY IN A DIAPHRAGM HAVING GREATLY IMPROVED WET STRENGTH. BECAUSE OF THE SUPERIOR STRENGTH OF THE IMPREGNATED DIAPHRAGM, THEY CAN BE EMPLOYED IN THE ELECTROLYTIC CELL WITHOUT SUPPORT AND CAN BE SUBJECTED TO THE CONDITIONS OF LAMINATION SO AS TO BE COMBINED ON AN INSEPARABLE SHEET OR LAYER OF WIRE MESH OF A PLASTIC WOVEN FABRIC OR A SINTERED POROUS PLASTIC AND EMPLOYED IN LAMINATED FORM AS THE DIAPHRAGM IN AN ELECTROLYTIC CELL.
