Abstract

The invention belongs to the technical field of ion exchange membranes, and particularly relates to a high-flatness reinforced net for an ion exchange membrane and application of the high-flatness reinforced net. The high-flatness reinforced net for the ion exchange membrane comprises warp yarns and weft yarns which are composed of polytetrafluoroethylene filaments and polyester filaments, and the diameter phi of the polytetrafluoroethylene filaments and the diameter phi of the polyester filaments respectively meet the following conditions: T represents the thickness value of the reinforced net after calendaring treatment. By improving the warp yarns and the weft yarns for the reinforcing net, the reinforcing net not only can meet the requirement of the ionic membrane on the strength, but also can provide a flat framework for the ionic membrane base membrane, so that the flatness of the ion exchange membrane is improved.

Description

Technical field [0001] The present invention belongs to the technical field of ion exchange membranes, and in particular to a high average reinforcing network for ion exchange films and their applications. Background technique [0002] Since the ionic membrane membrane itself prepared by the ion exchange resin is poor and the strength is low. It is easy to cause damage to the ionic membrane due to external effects such as bending, stretching, vibration, fluid impact during actual installation and use. The ionic membrane is typically enhanced using an enhancement net having a certain openness ratio. As described in U.S.P. NO 4324606, U.S.P.NO4477321, CN 101780376B, CN103252169A, and the like. [0003] The enhancement network is an important way to increase the mechanical strength and size stability of ion exchange membranes. If the network wants to play the skeleton support, it is necessary to embed the ionic membrane matrix. The peeling force is small, and the enhancement network...
