Title:
ION-EXCHANGE MEMBRANE, PRODUCTION METHOD OF ION-EXCHANGE MEMBRANE, AND ELECTROLYTIC TANK
Document Type and Number:
Japanese Patent JP2020204094
Kind Code:
A
Abstract:
To provide an ion-exchange membrane, a production method of the ion-exchange membrane, and an electrolytic tank, which can reduce an electrolytic voltage in electrolysis and can further display a stable electrolytic performance with little influence on the electrolytic performance due to a contaminant in an electrolyte.SOLUTION: An ion-exchange membrane comprises: a membrane body including a fluorine-based polymer having an ion-exchange group; and a coating layer arranged on at least one surface of the membrane body. The coating layer includes inorganic particles and a binder. The mass ratio of the binder is 0.3 or more and 0.9 or less to the total mass of the inorganic particles and the binder in the coating layer. A coverage factor of the membrane body by the coating layer is 50% or more.SELECTED DRAWING: None
