Tape casting mechanism for producing ionic membrane through membrane belt tape casting method

Abstract

The invention discloses a tape casting mechanism for producing an ionic membrane through a membrane belt tape casting method. The tape casting mechanism comprises a material trough mechanism and a scraper; the two sides of a material trough are provided with L-shaped installation lugs, so that the material trough mechanism is formed, and the material trough mechanism is connected with and fixed toan inclined guide plate of an unwinding mechanism through the L-shaped installation lugs on the two sides by a plurality of handle screws; suspension loops are installed at the two ends of the scraper and fixed to a slide block capable of moving on a guide rail; the guide rail is connected to a supporting beam connected with the unwinding mechanism; and the scraper is located in front of the supporting beam, and the material trough mechanism is located in front of the scraper. According to the tape casting mechanism for producing the ionic membrane through the membrane belt tape casting method, a material flowing mechanism in a sealed mode is adopted, the problems that in the material flowing process, a membrane is formed on the surface of slurry, and the viscosity of the slurry in a material trough is changed are solved, and the length of an obtained membrane is continuous; and the requirements for batch continuous production are met, the cost is reduced, manpower is decreased, and the labor intensity is relieved.

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...
