Abstract

L'invention a pour objet un diaphragme destiné à l'électrolyse d'un chlorure alcalin, constitué par un enchevêtrement de fibres d'un polymère capable d'engendrer une paire de couches de surface de résistance mécanique accrue quand il est soumis aux conditions d'environnement d'une telle cellule pendant environ deux semaines, une dimension de la section transversale desdites fibres étant inférieure ou égale à environ 4 mu m et ledit diaphragme ayant une perméabilité comprise entre 0,1 et 5 x 10**-9 C.G.S. Selon l'invention, est incorporé audit diaphragme environ 5 à 80 % en poids d'une matière minérale hydrophile stable dans l'environnement de la cellule, ladite matière hydrophile étant sous la forme de particules de grosseur inférieure à 1 mu m, de façon que la caractéristique de tension d'une cellule comportant un tel diaphragme soit améliorée au début de la période d'utilisation de cette cellule.
