Title:
REINFORCED ELECTROLYTE MEMBRANE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2013/129399
Kind Code:
A1
Abstract:
Provided are: a reinforced electrolyte membrane that is less susceptible to damage, such as cracks, at the time of handling the reinforced electrolyte membrane from after the production thereof to before conditioning operations for alkali chloride electrolysis and at the time of installing the reinforced electrolyte membrane in an electrolytic tank for conditioning operations; and a method for producing said reinforced electrolyte membrane. Disclosed is a reinforced electrolyte membrane (1) in which an electrolyte membrane (10) including a fluorine-containing polymer having an ion-exchange group is reinforced with a woven fabric (20) made of reinforcing yarns (22) and sacrifice yarns (24), wherein: the sacrifice yarns (24) remain in the electrolyte membrane (10); voids are formed around the sacrifice yarns (24) and between the electrolyte membrane (10); and, given that A is the sum of the cross-sectional area of the sacrifice yarn (24) and the cross-sectional area of the void and B is the cross-sectional area of the sacrifice yarn (24), 2000 µm2
