Abstract

The invention discloses an enhanced perfluorinated ion membrane tape-casting machine. The upper surface of a lower drying tunnel (24) is connected with an upper drying tunnel (17) through a plurality of connecting bases (26) into a whole; the lower drying tunnel (24) and the upper drying tunnel (17) are supported by a plurality of supporting mechanisms (25); one end of each of the upper drying tunnel (17) and the lower drying tunnel (24) is connected with a machine head mechanism (2); the other end of each of the upper drying tunnel (17) and the lower drying tunnel (24) is connected with a machine tail mechanism (20); a steel band (19) which penetrates through profile cavities of the upper drying tunnel (17) and the lower drying tunnel (24) is arranged between a driving roller (3) and a driven roller (21); a foam breaker (9) is positioned at the upper face of a bracket (54) on the upper drying tunnel (17); the upper end of the foam breaker (9) is connected with a feeding pipe; the lower end of the foam breaker (9) is connected with a feeding inlet of a tape-casting mechanism (7). The tape-casting machine provided by the invention can continuously produce enhanced ion membrane products with good isotonicity, high quality and uniform thickness in a batch, and can also meet the requirement of mass production, the production efficiency is improved, and film-forming quality is guaranteed.

Description

technical field [0001] The invention relates to an ion membrane manufacturing device, in particular to an enhanced perfluorinated ion membrane casting machine. 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 membrane products. The mass production methods of this product mainly adopt extrusion method, casting film method and casting method . 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. The film casting method is to cast a film by slowly evaporating and crystallizing the casting liquid at a heating temperature 10-30°C lower than the boiling point of the solvent. During the crystallization process of the solute, the casting plate and the casting liquid in it are in a static closed Space, under the radiant he...
