Background
The diaphragm with ion exchange function adopted in the industries of water electrolysis hydrogen production, fuel cells, chlor-alkali electrolysis and the like is a reinforced perfluorinated ion exchange membrane, the ion membrane is formed by adding a reinforced base material such as PTFE mesh and a microporous PTFE film in a common ion membrane, and the reinforced base material can be understood to form a reinforcing mesh in concrete, so that the tensile strength of the ion membrane is enhanced.
The batch production method of the enhanced perfluorinated ion exchange membrane mainly adopts a spin coating method, a casting film method, a screen printing method, a spraying method and a dipping method. However, the films prepared by the methods have high raw material cost, large solvent consumption, difficulty in controlling the thickness, uneven thickness of the prepared films, low production efficiency and incapability of continuous production. The casting method is that the raw material is dissolved in organic solvent, and then the solution is mixed into viscous solution, and the viscous solution is cast on a smooth rotator which is flat and uniform, and a film is formed by baking.

The problem of slippage and unevenness of the mesh cloth when the mesh cloth is paved on a steel belt easily occurs, so that the phenomenon of uneven thickness can be generated when slurry is cast; the blowing defoaming still has the problem that bubbles cannot be eliminated completely, and meanwhile, the slurry flows due to blowing, and the phenomenon of uneven thickness can also occur; because the reinforcing mesh cloth is firstly paved on the steel belt and then coated with the ionic membrane slurry in a casting way, the reinforcing mesh cloth is finally distributed on one side of the product and is not clamped in the ionic membrane.
