Abstract

The invention discloses a casting mechanism for producing ionic membranes by a film tape casting method, which includes a trough mechanism and a scraper, and L-shaped mounting ears are arranged on both sides of the trough to form the trough mechanism, and the trough mechanism passes through the two sides The L-shaped mounting ears are connected and fixed by a plurality of handle screws and the inclined guide plate of the unwinding mechanism; hanging ears are installed at both ends of the scraper, and the hanging ears are fixed on the slider that can move on the guide rail, and the guide rail is connected with the unwinding mechanism. On the support beam connected to the roll mechanism, the scraper is located in front of the support beam, and the trough mechanism is located in front of the scraper. The casting mechanism for the production of ionic membranes by the film tape casting method provided by the embodiments of the present invention adopts a sealed flow mechanism, which solves the problem of changes in the conjunctiva on the surface of the slurry and the viscosity of the slurry in the trough during the flow process, making the system The length of the film has been continuous; it meets the needs of batch continuous production, saves costs, reduces manpower, and reduces labor intensity.

Description

technical field [0001] The invention relates to a manufacturing device of an ion membrane, in particular to a casting mechanism for producing an ion membrane by a film tape casting method. Background technique [0002] Most of the ion exchange diaphragms used in water electrolysis hydrogen production, fuel cells, chlor-alkali electrolysis and other industries are perfluorinated ion exchange membrane products. The mass production methods of this product mainly adopt extrusion method, casting film method and casting method. Law. The extrusion method is to extrude the perfluorosulfonic acid ion exchange resin into a film through a high-precision screw under a certain temperature and pressure. This method requires high equipment and good ion membrane preparation accuracy. 220°C, so fish eyes and pinholes are prone to appear during the extrusion process. The film casting method is to cast a film by slowly evaporating and crystallizing the casting liquid at a heating temperature...
