Title:
電解用イオン交換膜の製造方法および電解用イオン交換膜
Document Type and Number:
Japanese Patent JP6756329
Kind Code:
B2
Abstract:
To provide a process for producing an ion exchange membrane for electrolysis which has a low membrane resistance and which is capable of reducing the electrolysis voltage during the electrolysis, even if the membrane strength is increased, an ion exchange membrane for electrolysis, a precursor membrane of an ion exchange membrane for electrolysis, and an electrolysis apparatus. In a fluorinated polymer having groups convertible to ion exchange groups, a reinforcing fabric 20A formed by weaving covered yarns 21 each comprising a reinforcing fabric 22 and a sacrificial material covering at least a portion of the outer peripheral surface of the reinforcing yarn 22, to produce a precursor membrane of an ion exchange membrane, and from the precursor membrane, at least a portion of the sacrificial material in the reinforcing fabric is eluted to form a reinforcing material and at the same time, the groups convertible to ion exchange groups are converted to ion exchange groups, to produce an ion exchange membrane for electrolysis.
