Abstract
The invention discloses a high-strength and high-heat-transfer carbon fiber graphite pipe and a production method thereof; the carbon fiber graphite pipe comprises a graphite pipe body containing short-silk carbon fibers and resin components; a carbon fiber layer covers outside the graphite pipe body; and the production method comprises steps such as mixing of ingredients, manufacturing of cakes, manufacturing of pipes and twisting with the carbon fiber layer. The carbon fiber graphite pipe overcomes the weakness of brittleness in pure graphite pipes and has the advantages of high strength, high pressure resistance, excellent heat transfer property, strong corrosion resistance and high temperature resistance; and the production process is simple and convenient to operate.
Description
Technical field
The present invention relates to a kind of graphite-pipe technology, particularly a kind of high strength, High Heat Transfering Carbon Fiber Graphite Pipe And Production Mode.
Background technique
Existing pure graphite-pipe due to its reason such as structure, material, intensity, temperature conductivity, corrosion-resistant etc. in there is undesirable part.
Summary of the invention
The object of this invention is to provide a kind of high strength, High Heat Transfering Carbon Fiber Graphite Pipe And Production Mode.
Technological scheme of the present invention is as follows:
A kind of high strength, high heat transfering carbon fiber and graphite pipe, it is characterized in that: comprise the graphite body containing short silk carbon fiber, resinous principle, graphite-pipe is external is surrounded by carbon fiber layer.
Graphite body containing short silk carbon fiber, resinous principle comprises following weight proportion composition:
Graphite 10-25%, resin, 50-70%
Resin curing agent 0-10%, short silk carbon fiber, 15-25%
Resin is phenolic resin or furfural acetone resin, polyflon, and resin curing agent is benzene sulfonyl chloride or ethyl-sulfate.The weight of carbon fiber layer is equivalent to 3-10% of graphite-pipe body weight.
A production method for high strength, high heat transfering carbon fiber and graphite pipe, is characterized in that: comprise the following steps: successively
1. to prepare burden mixing: superfine granule plumbagos more than 200 orders and resin, resin curing agent, short silk carbon fiber are uniformly mixed;
2. cake processed: above-mentioned mixture is made cake block in cake-making machine;
3. tubulation: cake block is put into tube producer and makes body;
4. be wound around carbon fiber layer: outside the body extruded from tube producer, be wound around one deck carbon fiber layer.
The advantages such as product of the present invention overcomes the fragility weakness of pure graphite-pipe, has intensity high, can be high pressure resistant, and temperature conductivity is extremely superior, and corrosion resistance is strong, high temperature resistant; And production technology is simple, easy to operate.
Accompanying drawing explanation
Accompanying drawing is product structure schematic diagram of the present invention.
