The film components used in silicon carbide film are designed and made according to the production needs of industrial enterprises and the requirements of engineering equipment. The film shells of different specifications can realize the centralized loading of silicon carbide film components with different outer diameters and different areas. The membrane area of a single membrane component varies from 0.2 to 20 square meters. The membrane equipment can integrate different membrane components in various forms according to the actual needs of users, and the design of any membrane area can be completed.
