Embodiment Construction

[0025] The following provides a specific implementation manner expressed by the drawings in the description.

[0026] A production line for ultra-thin flexible graphite paper, comprising five major parts: a graphite expansion device 1, a desulfurization device 11, a material distribution device 41, a calendering device 24 and a paper rolling device 44.

[0027] Graphite expansion device 1 as attached figure 2 As shown, a cylindrical cylinder vertical expansion furnace 1' is adopted, which is composed of a shell 2, which is composed of an insulating cotton layer 3, an insulating brick layer 4, an electric heating tube 5, and an electrode material expansion tube 6. The lumen of the expansion tube is Graphite Expansion Channel 7. The top of the expansion furnace is provided with a feed port 9, which is connected to the feed hinge, and the bottom is provided with a discharge port 10, which is connected to the feed port of the desulfurizer through a pipeline. Mullite bricks are ...

Abstract

The invention relates to a production line of ultrathin flexible graphite paper, and relates to graphite paper production line equipment. The production line of the ultrathin flexible graphite paper comprises a graphite expansion apparatus, a desulphurization apparatus, a material-distributing apparatus, a calendaring apparatus and a paper-rolling apparatus. The expansion apparatus is a vertical expansion furnace. The desulphurization apparatus comprises a material-distributing groove and a material-distributing spine roller. The calendaring apparatus is composed of a plurality of calendaring machines in arrangement. The calendaring machines are provided with calendaring gap adjusting mechanisms. The production line of the ultrathin flexible graphite paper has the beneficial effects that high pure acidified graphite is used as a raw material; the vertical electrical heating expansion furnace is employed, so that pollutions can be prevented and the graphite is expanded into vermicular graphite; the cloth spindle roller with densely arranged spindle needles along a spiral line is used, so that the thickness of the cloth is uniform; and alternatively arranged calendaring machines with large and small diameter press rollers, middle convex press rollers and a laser thickness gauge closed-loop control system are used by the calendaring apparatus, so that calendaring gaps can be adjusted automatically. With comprehensive application of the above effective measures, high pure ultrathin flexible graphite paper is produced; applications are wide; and blanks of the ultrathin flexible graphite paper and production in China are filled.

Description

Technical field: [0001] The invention relates to technical equipment for producing flexible graphite paper. Background technique: [0002] Graphite has stable chemical properties, and its finished product graphite paper is soft and corrosion-resistant. It is widely used in petroleum, chemical, machinery, electric power and other industries. It is an ideal new sealing material. At present, high-purity, ultra-thin graphite paper is also widely used in high-tech fields such as aerospace and national defense. [0003] Common flexible graphite paper has been produced in the prior art, but due to the layout of the production line and the design of each component are not refined and scientific enough, such as the use of oil-heated or natural gas-heated horizontal expansion furnaces that easily affect the purity of graphite, simple The desulfurization device does not remove sulfur completely, the arrangement and combination of multiple presses with the same diameter rollers and the...
