Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is that microwave attenuation power of the present invention can the structural representation of cutting carbon fiber electrothermal plate embodiment.
Fig. 2 is that microwave attenuation power of the present invention can the euthermic chip Rotating fields schematic diagram of cutting carbon fiber electrothermal plate embodiment.
Fig. 3 is the A-A cutaway view of Fig. 2.
In figure, the upper decorative layer of 1-, the upper insulating barrier of 2-, 3-carbon fiber heating non-woven paper, 4-electrode copper strips, insulating barrier under 5-, decorative layer under 6-, 7-power supply contact, 8-gap.
Embodiment
Fig. 1 is that a kind of microwave attenuation power can cutting carbon fiber electrothermal plate, is from up to down overlapping successively by upper decorative layer 1, upper insulating barrier 2, heat generating core lamella, electrode copper strips 4, lower insulating barrier 5, lower decorative layer 6 and makes through pressing.
Wherein heat generating core lamella as shown in Figure 2: the euthermic chip several carbon fiber heating non-woven papers 3 being cut to the strip with same size specification, then be laid in parallel to each other between insulating barrier 2 and lower insulating barrier 6, between each euthermic chip, be provided with the gap 8 of 6 ~ 8 millimeters.Insert the two ends up and down of the carbon fiber heating non-woven paper of strip again with two electrode copper strips 4 respectively, each carbon fiber heating non-woven paper is formed and is connected in parallel, these two copper strips i.e. as power connector end and thereon source of welding current contact 7.
Above-mentioned microwave attenuation power can manufacture by cutting carbon fiber electrothermal plate according to the following steps:
(1) first the carbon fiber heating non-woven paper of selected power, the euthermic chip of the strip of same dimensions is cut into by specification.
(2) according to the specification cutting of electric hot plate as the woodgrained paper of decorative layer.
(3) according to the specification cutting of electric hot plate as the epoxy insulation glass cloth of insulating barrier.
(4) by bottom-up order, first lay the woodgrained paper as lower decorative layer 7, secondly lay the epoxy insulation glass cloth as lower insulating barrier 6.
(5) lay heat generating core lamella: multiple the carbon fiber heating non-woven papers cut, as parallel laid above the epoxy insulation glass cloth of lower insulating barrier, adjacent carbon fiber heating non-woven paper retains 6 ~ 8 millimeters, interval.
(6) insert the two ends up and down of often opening carbon fiber heating non-woven paper with two copper strips as electrode respectively, make each carbon fiber heating non-woven paper connect (Fig. 2) with parallel way; Specific practice is upper end or the lower end of copper strips being inserted each euthermic chip with top-bottom cross, copper strips is formed and corrugatedly to intert up and down in carbon fiber heating non-woven paper, and copper strips is connected (Fig. 3) successively respectively with the upper and lower surface of carbon fiber heating non-woven paper.
(7) lay successively on heat generating core lamella as on insulating barrier 2 epoxy insulation glass cloth and as on the woodgrained paper of decorative layer 1.
(8) electric hot plate laid is carried out hot pressing on hot press.
(9) electric hot plate after hot pressing is carried out by specification trimming.
(10) insulating barrier is removed to the power supply contact 7 place polishing on two electrode copper strips 4 of electric hot plate, welding power source line, and butt joint place insulation processing.
Because above-mentioned electric hot plate adopts multiple equivalent specifications euthermic chips, parallel interval is combined into heating circuit in parallel, can cutting at interval of place, the electric hot plate of variable-width, cropped electric hot plate all can be used, and to several specification electric hot plate of production, is simplified to and produces a kind of specification electric hot plate, can directly cutting use at the construction field (site), very convenient.
In addition, adopt as copper strips and the carbon fiber heating non-woven paper of electrode and intert mode up and down and be connected and make the contact of copper strips and carbon fiber heating non-woven paper firmly permanent.Adopt overlay method as the copper strips of electrode effect and conductive paper processing method in prior art, be exactly connect only overlapping with the side at conductive paper edge from start to finish for copper strips, top lower insulation plate pressure force keeps in touch dynamics, in external pressure to electric hot plate distortion with when bending, resistance is small and weak, and long-time use can cause losing contact force gradually between copper strips and conductive paper, and resistance becomes large gradually, power is weak gradually, and useful life shortens.
The microwave attenuation power of the present embodiment not only can greatly reduce electric heating and pulls decay power by cutting carbon fiber electrothermal plate, improve product quality, reduce failure rate, extend product useful life, and change carbon fiber electrothermal plate can not cutting use drawback, improve product ease of use, and innovate to some extent in technological level and product quality and break through.
Above-described embodiment of the present invention, does not form limiting the scope of the present invention.Any amendment done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within claims of the present invention.
