Embodiment 1

[0022] see figure 1 Shown is a schematic diagram of the implementation of the production of plate-shaped impermeable graphite.

[0023] The plate-shaped graphite material 1 to be impregnated is fixed with a clamping tool 2, and there is a storage space for an impregnating agent 3 under the clamping tool 2, and the clamping tool 2 passes through a pipeline 4 and a control valve 5, a booster pump 6, and an impregnating agent storage tank 7 Connected into one; when working, start the booster pump 6 to press the impregnating agent in the impregnating agent storage tank 7 from one side of the graphite material 1, and the impregnating agent penetrates into the graphite material and fills the original gap, when the other side of the graphite material After all the impregnating agent overflows on the side, the impregnating process is completed; clean up the excess impregnating agent on the surface of the graphite material, and then adopt an appropriate process to solidify (plasticize)...

Embodiment 2

[0025] see figure 2 Shown is a schematic diagram of the implementation of the production of cylindrical impermeable graphite.

[0026] The cylindrical graphite material 1 to be impregnated is fixed with a clamping tool 2. The lower part of the clamping tool 2 and the inner cavity of the graphite material are the storage space for the impregnating agent 3. The clamping tool 2 passes through the pipeline 4 and the control valve 5, the booster pump 6, The impregnating agent storage tank 7 is connected into one; when working, start the booster pump 6, control the valve 5 to remove the air in the inner cavity of the graphite material 1, press the impregnating agent in the impregnating agent storage tank 7 into the inner side of the graphite material 1, and the impregnating agent penetrates into the When the other side of the graphite material has all the impregnating agent overflowing, the impregnating process is completed; clean up the excess impregnating agent on the surface of ...

Embodiment 3

[0028] see image 3 Shown is a schematic diagram of the implementation of the production of bulk impermeable graphite.

[0029] The block-shaped graphite material 1 is drilled with staggered longitudinal holes 8 and two sets of transverse holes 9; the block-shaped graphite material 1 to be impregnated is fixed with a clamping tool 2, and the clamping tool 2 is connected with the longitudinal channels in the graphite material. Enclosing the storage space of the impregnating agent 3, the clamping tool 2 is integrated with the control valve 5, the pressurizing pump 6, and the impregnating agent storage tank 7 through the pipeline 4; when working, the pressurizing pump 6 is started, and the control valve 5 removes the graphite material 1 The air in the longitudinal channel presses the impregnating agent in the impregnating agent storage tank 7 into the longitudinal side of the graphite material 1, and the impregnating agent penetrates into the graphite material and fills the origi...

Abstract

The invention discloses a production method for impermeable graphite. According to the method, through a certain clamping tool, a flowable impregnating agent is pressed in a graphite material from one side of the graphite material and flows to the other side of the graphite material by using a pressurization method, and in such a process, holes in the graphite material are filled with the impregnating agent; and then through certain technology processing, the impregnating agent is allowed to be immobilized in the graphite material and integrated with the graphite material, so impermeable graphite is prepared. The impermeable graphite may be in a plate, cylinder or block shape. The production method provided by the invention can rapidly produce the impermeable graphite and has high work efficiency.

Description

technical field [0001] The invention relates to a production method of graphite, in particular to a method for making impermeable graphite by using artificial graphite as a base material and filling pores in the graphite with various substances with good chemical stability. Background technique [0002] Graphite has excellent chemical stability and thermal stability, and is widely used in industrial fields. In industrial applications, artificial graphite is the mainstay; and during the production process of artificial graphite, due to the decomposition of some raw materials into gas, many irregular pores with different sizes and interconnected tiny pores are formed inside the product. And other media have serious permeability, which affects its application in industry; in order to make up for this shortcoming, it is necessary to take certain measures to fill the pores to make impermeable graphite. [0003] The method of impregnation is usually used to manufacture impermeabl...
