Fig. 2 is that the carbon fiber wire intermediate shown in Fig. 1 is bonded in the structural representation on heat-resisting main shaft by adhesive phase.
The specific embodiment
In order more clearly to understand technology contents of the present invention, especially exemplified by following examples, describe in detail.
Refer to shown in Fig. 1-Fig. 2, the method that carbon fiber wire of the present invention is manufactured carbon-to-carbon composition heating wire for basis comprises the following steps:
(1) at the one side of described carbon fiber wire 1 or the relative two-sided adhesive phase 2 that arranges, on described adhesive phase 2, organic synthesis rete 3 is set, obtaining carbon fiber wire intermediate 10(refers to shown in Fig. 1 and Fig. 2), the fusing point of wherein said organic synthesis rete and described adhesive phase is below 350 ℃;
(2) described carbon fiber wire intermediate 10 is bonded on heat-resisting main shaft 4 (shown in Figure 2) by described adhesive phase 2;
(3) then in oxidation furnace, heat-treat;
(4) then in non-oxidising furnace, heat-treat;
(5) finally from described heat-resisting main shaft 4 separation, obtain carbon-to-carbon composition heating wire.
Above-mentioned carbon fiber wire 1 refers to the polyacrylonitrile from PAN() select any one to use based carbon fiber silk, pitch-based carbon fiber silk, vegetalitas artificial carbon's filament and viscose carbon fiber wire, no matter sub-thread number or multiply are counted carbon fiber wire and can be adopted and produce carbon-to-carbon composition heating wire of the present invention.
The main component of organic synthesis film 3 is to contain in a large number carbon, in the following temperature environment of 350 degree, easily melting (degree of thermal decomposition be become from solid liquid) is convenient in thermal decomposition, for example, so preferably adopt thermoplasticity material (o-phenyl phenol, O-phenylphenol, english abbreviation OPP, it is a kind of important meticulous Organic chemical products).But in the present invention, do not limit synthetic material, can adopt natural emulsion yet.
Adhesive 2 refers to the material with adhesive effect, all-purpose adhesive for example, hundred glue.
Shown in Figure 1, in the outside of organic synthesis film 3, can also pass through the other bonding heterolayer 5 of adhesive phase 2, heterolayer 5 is to be shaped on heat-resisting main shaft for convenient, for example glass cement.
Heat-resisting main shaft 4 refers to that heat resistance is more than 2000 degree under non-oxide atmosphere, uses smooth surface, graphite rod easy to process.While arranging carbon fiber wire intermediate 10 with arbitrary shape on heat-resisting main shaft 4, adhesive phase 2 must be attached on heat-resisting main shaft 4 (shown in Figure 2).On carbon fiber wire 1, scribble adhesive phase 2, for example, so can arbitrary shape (spirality) shaping conveniently carry out automated production on heat-resisting main shaft 4.
On heat-resisting main shaft 4 two ends of the carbon fiber wire intermediate 10 of arbitrary shape can with other carbon fiber wire intermediate 10 for example the carbon fiber wire intermediate of sub-thread number pinion rear fixing.
Carbon fiber wire intermediate 10 and heat-resisting main shaft 4(call bond in the following text) be that a large amount of disposable oxidation furnaces of putting into are heat-treated.Be below oxidation technology: at this moment the temperature of oxidation furnace can not surpass 350 degree (the oxidation point of carbon fiber wire 1), will reach the temperature of adhesive phase 2 complete meltings in the unvaporized situation of organic synthesis rete 3 simultaneously.Melt completely after organic synthesis rete 3, infiltrate through porous carbon fiber wire 1 space.While now reducing furnace temperature, the organic synthesis film absorbing in melting infiltrates through carbon fiber wire 1 space and solidifies, and even without heat-resisting main shaft, still keeps shape and hardness.
Finish, after above-mentioned heat treatment process, in connection with thing, to put on non-oxidising furnace and again heat-treat.Non-oxide process refers to passivation atmosphere or vacuum state, but the present invention heat-treats in passivation atmosphere stove.The gas using in passivation stove (being designated hereinafter simply as inert gas) is in nitrogen, argon, hydrogen, to select arbitrarily.But, consider that heating is that temperature reaches 2000 degree again, at high temperature, preferably selection is the most suitable with the argon that carbon fiber wire 1 is difficult for reacting.
In non-oxide atmosphere stove, produce carbonization and reduction process simultaneously, while progressively improving furnace temperature, melting in above-mentioned oxidation technology, the organic synthesis film solidifying are carbonized, form carbon-to-carbon composition, composition is formed to other compositions that do not make a difference to be also thermal decomposited, be evaporated to outside stove together with gas, thereby form high purity carbon-carbon composition heating wire with high temperature safe performance.

3. to be arranged in diameter be 5mm to carbon fiber wire intermediate 10, and length is that on the graphite rod of 30 centimeters, adhesive phase 2 is attached on graphite rod, with spirality, twines 40 circles.
4. above be attached to 3 carbon fiber wire intermediate 10 tightens that enclose other for carbon fiber wire intermediate 10 two ends on graphite rod.
5. above 1000 bonds are dropped into oxidation furnace, after restriction extraneous air flows into, in normal temperature, furnace temperature is brought up to 250 degree with the speed of 1 degree per minute, in 250 degree temperature environments, maintain after 30 minutes, stop heating, implement nature cooling.
6. on oxidation furnace, take out cooling bond, put on argon gas stove with the speed of 0.5 degree per minute temperature is brought up to 2000 degree, stop heating maintaining 2 hours in 2000 degree temperature environments after, carry out nature cooling.
7. from oxidation furnace, take out chilled bond, from graphite rod, isolate carbon-to-carbon composition heating wire.
Therefore, the carbon fiber wire 1 that the invention relates to sub-thread number or multiply number is made the technological invention of carbon-to-carbon composition heating wire, specifically, , on carbon fiber wire 1 two sides of sub-thread or multiply, adhesive phase 2 is set, organic synthesis rete 3 is set on adhesive phase 2 again, the carbon fiber wire of above-mentioned overlay film, be that carbon fiber wire intermediate 10 is arranged with arbitrary shape on heat-resisting main shaft 4, two-end part is fixing with the carbon fiber wire intermediate 10 of sub-thread number, interim through peroxidating, carbonization, reduction process, from the separated carbon-to-carbon composition heating wire that keeps shape of heat-resisting main shaft 4, with this, improve heat-resisting effect, the carbon-to-carbon composition heating wire of surface uniform is finally provided.Compare with original mode, the invention enables and realize that technique is simplified and automation, a large amount of produce had may, can reuse spindle material and reduce production costs, improve heater surface quality, there is the effect that can produce carbon-to-carbon composition heating wire.
