る。Porous carbon plates are used in a variety of applications due to their excellent heat resistance, chemical resistance, electrical conductivity, and breathability.
Depending on the application, it may be required to be partially impermeable, ie, sealed. However, it is necessary to use a sealing material that has chemical resistance and heat resistance comparable to that of carbon, and one such material is wire resin.

の輪郭が不正確になる。Is it possible to partially seal the above porous carbon plate with a wire dipping resin material by applying a resin dispersion to the area to be sealed and firing it? There is a problem in that it is difficult to impregnate the internal pores of the carbon plate with 'tl'l fat, and therefore the sol properties are poor. Another option is to mask the non-sealed area and vacuum impregnate it, but in this case, it is not possible to completely seal the area, and a certain amount of liver fat will seep into the edges of the masked area, resulting in unnecessary impregnation. Inaccurate contours of sealed or unsealed areas.

法である。The present invention provides a method for sealing porous carbon plates without the disadvantages mentioned above. That is, the method for sealing a porous carbon plate according to the present invention involves applying a dispersion of a linear resin as an adhesive binder to a portion of a porous carbon plate to be sealed, baking the applied resin, and forming the baked resin layer.
This method is characterized by heat-pressing a linear resin film to the surface.
以下、図面により本発明を説明する。The present invention will be explained below with reference to the drawings.

のものを用いる。In FIG. 1 and FIG. 2, l is a porous carbon plate, and the thickness is 1 to 5 mm T. 2 is a linear resin layer coated and sintered on the sealed portion of the porous carbon plate 1. For example, an aqueous dispersion of polytetrafluoroethylene is coated, this is heated and dried, and then fired at 390°C. It can be provided by 3 is a linear resin film having a thickness of about 20 to 200 μm, which is heat-pressed onto the sintered linear resin layer 2 described in “2”. This linear resin film is made of polytetrafluoroethylene, tetrafluoroethylene-hexafluoropropylene copolymer, tetrafluoroethylene rubber fluoroalkyl vinyl ether copolymer, etc., which has the same melting point as the sintered linear resin layer or Or use one with a low melting point.

The linear resin dispersion was a polytetrafluoroethylene aqueous dispersion (Polyflon D-manufactured by Daikin Co., Ltd.) with a concentration of 60% by weight.
2) was used. This dispersion was applied to a predetermined portion of a porous carbon plate as described above, dried at 100°C for 30 minutes, and the coated layer was fired at 390°C for 1.5 minutes to form an adhesive binder. Next, a 50 μm thick tetrafluoro ethylene-perfluoroalkyl vinyl ether copolymer film was heat-pressed at 3300°C. The pressure was 4 kg/d, and the heat-pressing time was 20 minutes.
