Embodiment Construction

[0006] A carbon paper continuous production method for automatic control of impregnation. The method has a PTFE (polytetrafluoroethylene) impregnator, which is connected to the PTFE liquid level controller, and the liquid level controller is connected to the tank containing the impregnated raw material PTFE (polytetrafluoroethylene), and the first end automatic weight gauge. Preset Automatic Control Program (Signal Collection Output Processor - Abbreviation Signal Transmitter). Carbon-based paper production diameter setting: 80cm, keep the header focus on substantially consistent. The impregnator depth is 0.9 meters, which is 0.4 meters wide. The bottom is provided with a circular guide roller. There are two circular guiding rollers in the upper portion, and the carbon retained paper is entered by the upper leading roller, and the lower guide roller, and then the other The guide roller out of the impregnator is designed as a soft roller, and then a soft roller is added, and the tw...

Abstract

The invention relates to the technical field of hydrogen fuel cells, and concretely relates to a carbon paper continuous production method capable of automatically controlling the impregnation amount. According to the method, a PTFE (polytetrafluoroethylene) impregnator and a PTFE liquid level controller connected with the PTFE impregnator are adopted, the liquid level controller is connected with a tank filled with an impregnation raw material PTFE (polytetrafluoroethylene), and automatic weighing instruments are arranged at the head end and the tail end. An automatic control program (a signal collecting and outputting processor-a signal collecting and transmitting device for short) is preset. The production diameter of the carbon body paper is set to be 80 cm, and the head end emphasizes are kept basically consistent. The concentration of a dipping raw material PTFE water-phase dispersion is 60%. The dipping speed cannot exceed 2 m / min, so that air bubbling caused by too high speed is prevented. And the equipment always keeps working at a set liquid level according to the control signal.

Description

Technical field [0001] The present invention relates to the technical field of hydrogen fuel cells, carbon paper production series techniques. Specifically, it is a carbon paper continuous production method for automatic control of the impregnation amount. Background technique [0002] Carbon paper in Japan is the best quality of the gas diffusion layer of hydrogen fuel cells in foreign countries. However, it cannot be produced continuously. Secondly, Germany, Canada has production, quality is also good. There is no enterprise in China to produce a gas diffusion layer of hydrogen fuel cells - carbon paper. Colleges and universities studied deeper in Wuhan University of Technology. Second, Beijing Chemical Technology has many years of research. R & D and industrialization of carbon paper production related technical equipment are imminent. Inventive content [0003] In order to solve the above problems, it is an object of the present invention to provide a carbon paper continuous...
