Abstract[English]
Disclosed in the present invention is a diaphragm cloth for a water electrolysis cell. The diaphragm cloth is a woven fabric formed by high-temperature and acid-alkali resistant long-fiber multifilaments. The linear density of monofilaments in the long fiber multifilaments is 0.01-0.50 dtex, the diaphragm cloth has a maximum pore size of 6.00-30.00 μm, and an average pore size of 2.00-15.00 μm, and the ratio of the maximum pore size to the average pore size is greater than 1.00 and less than 3.00. The diaphragm cloth for a water electrolysis cell of the present invention has the characteristics of high ion permeability and air tightness.[French]
La présente invention concerne un tissu de diaphragme pour une cellule d'électrolyse de l'eau. Le tissu de diaphragme est un tissu tissé formé par des multifilaments à fibres longues résistant aux hautes températures et aux alcalis acides. La densité linéaire de monofilaments dans les multifilaments de fibre longue est de 0,01 à 0,50 dtex, le tissu de diaphragme présente une taille de pore maximale de 6,00 à 30,00 µm, et une taille de pore moyenne de 2,00 à 15,00 µm, et le rapport de la taille de pore maximale et de la taille de pore moyenne est supérieur à 1,00 et inférieur à 3,00. Le tissu de diaphragme pour une cellule d'électrolyse de l'eau de la présente invention présente les caractéristiques d'une perméabilité aux ions élevée et d'une étanchéité à l'air.[Chinese]
