An ion exchange membrane of a fluorinated polymer is bonded to a synthetic resin with a binder selected from the group consisting of fluorinated polymers, polyolefins and polyaryl ethers. The binder is in a form of a net, a cloth or a porous sheet so as to form an uneven interlayer.

Method of bonding ion exchange membrane of fluorinated polymer to

An ion exchange membrane electrolytic cell comprises an anode, a cathode, an anode compartment and a cathode compartment partitioned by an ion exchange membrane; an improvement characterized in that a gas and liquid permeable porous non-electrode layer is bonded to at least one of surfaces of said ion exchange membrane and said porous non-electrode layer is formed by coating electric non-conductive or conductive particles on the surface of a support to form a thin layer, transferring said thin layer onto the surface of said membrane and bonding said thin layer to said membrane by the application of heat and pressure.

Ion exchange membrane manufacture for electrolytic cell

Lamination of plastic film and shaped metal substrates is carried out by a pair of rolls which comprises one heat-resistant roll having a hollow for receiving at least a forward edge of the shaped metal substrate, on at least one of the surfaces of the roll. A laminated product having no defect or crease of the plastic film can be obtained.

Method of laminating plastic film and shaped metal substrates

A hard board containing a fiber web and a thermoplastic resin which composite is used as a noise absorption product is improved in that the surface and spaces between the fiber web are covered and filled with the resin, and wherein a plurality of finely formed crevices is formed in the resin covering the surface of the composite.
