It revolves vacuum pump and pressure in reaction chamber is evacuated to 10Pa hereinafter, being passed through Ar/H21000/1000sccm, air-flow steadily open toluene afterwards
Flow control is 1000sccm by gas valve, and toluene vapor, which enters, is cracked into rapidly active carbon species after reaction chamber, a large amount of living
Property carbon species be adsorbed onto quartz fiber surface, surface migration, collision, to realize the nucleation and growth of micro crystal graphite.Carbon materials
Material growth course is set as 120 minutes, closes toluene valve after growth rapidly, and by Ar/H2It is set as 300/
300sccm opens temperature-fall period.Cavity temperature to be reacted is down to room temperature, closes Ar/H2, open a position and take out sample.
The results showed that carrying out heat resistance experiment, test knot using fibre electroheating cloth of the liquefied gas flame gun to preparation
Fruit is when temperature is greater than 800 DEG C, and embrittlement phenomenon occurs in fiber cloth, illustrates that the fibre electroheating material of the present embodiment can be resistant to 800
DEG C high temperature.In the case where reaction temperature increases substantially, the experimental result of the upper example of high temperature resistance has obviously instead
Decline illustrates that the mode of magnetron sputtering cooperation copper can not obtain good result.Reason is analyzed, is magnetron sputtering mode to reflection
As a result can have an impact, applicant is covered nickel mode using magnetron sputtering and also tested, experimental result and magnetron sputtering copper example
It is similar, high temperature resistant degree can be all reduced, can be determined that magnetron sputtering mode can reduce fibre electroheating performance.
Specifically, applicant have observed that, the heating element of the method preparation of copper is sprayed by room temperature, not only increases material
Toughness and gas permeability, also improve the heat radiation area of material, and then further increase thermal conversion efficiency, may be implemented to approach
100% electric conversion efficiency.

4.86 Ω also answer the heating element 6 of one 3.89 Ω of parallel connection.Therefore the present embodiment is arranged one together on the outside of round table-like heating part
The cylindric heating part 23 in axle center, as shown in Figure 3, it is assumed that 23 diameter of cylindrical shape heating part is that 65mm then justifies through relevant calculation
23 length of tubular heating part is 79.4mm.23 parallel operation of round table-like heating part and cylindric heating part, round table-like heating part function
Rate about 267W, cylindric 23 power of heating part about 333W, during heating, circuit control panel 12 can be opened according to heating state
Close one or two heating part, so as to meet temperature it is constant in the case where, reduce electric energy loss.
Although the principle of the present invention is described in detail above in conjunction with the preferred embodiment of the present invention, this field skill
Art personnel are it should be understood that above-described embodiment is only the explanation to exemplary implementation of the invention, not to present invention packet
Restriction containing range.Details in embodiment is simultaneously not meant to limit the scope of the invention, without departing substantially from spirit of the invention and
In the case where range, any equivalent transformation based on technical solution of the present invention, simple replacement etc. obviously change, and all fall within
Within the scope of the present invention.
