Embodiment 1

[0023] ① Ingredients mixing: Stir and mix 10% of superfine graphite powder over 200 mesh (eg 200 mesh, 300 mesh, 500 mesh) with 70% phenolic resin, 0.5% resin curing agent-benzenesulfonyl chloride, and 19.5% short carbon fiber Uniform;

[0024] ② Cake making: Make the above mixture into cake pieces in a commercially available cake making machine;

[0025] ③ pipe making; put the cake into a commercially available pipe making machine to make the pipe body 1;

[0026] 4. Winding carbon fiber layer: outside the pipe body 1 extruded from the pipe making machine, a layer of carbon fiber layer 2 is wound, and the weight of the carbon fiber layer 2 is equivalent to 5% of the weight of the graphite pipe body 1 . That is, a high-strength, high-heat-transfer carbon fiber graphite tube containing the above-mentioned components by weight is obtained.

Embodiment 2

[0028] When the ingredients were mixed, the weight ratio of each component was:

[0029] Graphite 17%, furfurone resin 53%, resin curing agent-ethyl sulfate 6%, short carbon fiber 23%;

[0030] When the carbon fiber layer is wound, the weight of the carbon fiber layer is equivalent to 3% of the weight of the graphite tube body.

[0031] All the other are the same as in Example 1.

Embodiment 3

[0033] When the ingredients were mixed, the weight ratio of each component was:

[0034] Graphite 25% PTFE resin 59% short carbon fiber 16%;

[0035] When the carbon fiber layer is wound, the weight of the carbon fiber layer is equivalent to 10% of the weight of the graphite tube body.

[0036] All the other are the same as in Example 1.

Abstract

The invention discloses a high-strength, high-heat-transfer carbon fiber graphite tube and a production method thereof. The product includes a graphite tube body containing short carbon fibers and resin components, and the graphite tube body is covered with a carbon fiber layer; the production method includes mixing ingredients and making cakes. , pipe making, winding carbon fiber layer and other steps. The product of the invention overcomes the brittle weakness of pure graphite tubes, and has the advantages of high strength, high pressure resistance, extremely superior heat transfer performance, strong corrosion resistance, high temperature resistance, etc.; and the production process is simple and easy to operate.

Description

Technical field: [0001] The invention relates to a graphite tube. Background technique: [0002] The existing pure graphite tubes are unsatisfactory in terms of strength, heat transfer performance, corrosion resistance, etc. due to their structure and materials. Invention content: [0003] The object of the present invention is to provide a production method of a high-strength, high-heat-transfer carbon fiber graphite tube with high strength and high heat-transfer performance. [0004] Technical solution of the present invention is: [0005] A high-strength, high-heat-transfer carbon fiber graphite tube is characterized in that it includes a graphite tube body containing short carbon fibers and resin components, and the graphite tube body is covered with a carbon fiber layer. [0006] The graphite tube body containing short carbon fibers and resin components includes the following components by weight: [0007] Graphite 10-25% resin 50-70% [0008] Resin curing agent 0...
