The application relates to the technical field of
fiber diaphragms and a preparation method thereof, and discloses an aromatic polysulfonamide
fiber diaphragm and a preparation method thereof. The aromatic polysulfonamide
fiber diaphragm can be well applied to the preparation of the aromatic polysulfonamide fiber diaphragm, the structure of the aromatic polysulfonamide fiber diaphragm is reinforced, the
aromaticity of the aromatic polysulfonamide fiber diaphragm is released slowly, the softness and continuity of the aromatic smell are improved, and the aromatic polysulfonamide fiber diaphragm comprises a silk solution, a film forming structure, a
small hole forming structure and a pressure combining structure. The film forming structure comprises a roller pressing frame, two first driving rollers and two second driving rollers are rotationally connected in the roller pressing frame, a first variable frequency motor and a second variable frequency motor are installed outside the roller pressing frame, the first variable frequency motor is used for synchronous relative rotation driving of the two first driving rollers, the second variable frequency motor is used for synchronous relative rotation driving of the two second driving rollers, the two first driving rollers and the two second driving rollers are used for assisting the roller pressing of the silk solution to form a film, and two uncoiling assemblies are installed on the roller pressing frame.
