Describes a liquid-permeable diaphragm assembly for use in electrolytic cells, e.g., chlor-alkali electrolytic cells. The diaphragm assembly includes a foraminous cathode, a liquid permeable base mat comprising synthetic polymeric material that is at least partially resistant to the environment within the electrolytic cell on the foraminous cathode, and a topcoat of water-insoluble particulate material on the base mat. The topcoat is deposited on the base mat from an aqueous slurry comprising (i) at least one oxide, boride, carbide, nitride or silicate of a valve metal, (ii) clay mineral, (iii) hydrous metal oxide chosen from the hydrous oxides of magnesium, the hydrous oxides of zirconium, and mixtures of such hydrous metal oxides, and (iv) alkali metal polyphosphate.

L'invention concerne un ensemble diaphragme perméable aux liquides à utiliser dans des piles électrolytiques, par exemple des piles électrolytiques en chlore alcali. L'ensemble diaphragme comporte une cathode foraminée, un tapis de base perméable aux liquides comprenant un matériau polymère synthétique qui est au moins partiellement résistant au milieu dans la pile électrolytique sur la cathode foraminée, et une couche de finition en matériau particulaire insoluble dans l'eau sur le tapis de base. La couche de finition est déposée sur le tapis de base à partir de boue aqueuse comprenant (i) au moins un oxyde, un borure, un carbure, un nitrure ou un silicate d'un métal à effet de valve, (ii) un minéral argileux, (iii) un oxyde métallique hydraté choisi dans les oxydes hydratés de magnésium, de zirconium, et dans les mélanges de ces oxydes métalliques hydratés, et (iv) un polyphosphate de métal alcalin.
