Abstract

The utility model relates to a high temperature carbon fiber electric heating paper which is quickly heated up by face heating and is more particularly applicable to heating under high temperature. The utility model is characterized in that the surface of the flexible insulate material is stuck with carbon fiber, and after being cut into various shapes with different sizes as necessary, a power cable is induced out from the two end of the high temperature carbon fiber electric heating paper by using a copper foil electrode or a graphite electrode. When in use, by being wrapped with insulate material, the high temperature carbon fiber electric heating paper is available. The utility model has stable and quick heating, shortens the working time, has long service life, fairly high heat efficiency and high applicable temperature, improves the labor productivity, reduces the production cost, saves the working energy consumption and is adjustable and controllable, thereby being good for ensuring the product quality and improving the output. Moreover, the technology of the utility model has extensive applicability and derives a plurality of new products, thereby greatly improving the industrial technology level.

Description

The high-temperature carbon fiber electrothermal paper

Technical field

The utility model relates to a kind of high-temperature carbon fiber electrothermal paper, and what be applicable to various civilian, industrial, medical, field of petrochemical industry is the heating field of medium with air, liquid or fluid.

Background technology

In recent years, quickening along with the urban construction paces, the development of economic industry, the energy more and more becomes the focus of social concerns, how to improve rate of energy, increasing its efficient, reduce production costs, guarantee that product quality more and more becomes the emphasis that each manufacturer is competitively studied, also is a kind of approach that its product provides occupation rate of market.

At present, the electric heating element of the normal electric heating products that uses is as 1: resistance wire etc. are generally linear heating, the generated heat constraint of material of heat exchange area is difficult to accomplish planar even heating, short because of its useful life, the heating-up time is long, surface temperature is inhomogeneous, the heat efficiency is low, power consumption is big, use cost is high, and is and wayward; 2: existing carbon fiber electric heating paper is to be mixed and made into paper pulp with chopped carbon fiber, because of the paper pulp carburizing temperature is lower, so its heating temp is also lower.

At this market situation, again in conjunction with a kind of new market demand, a kind of high-temperature carbon fiber electrothermal paper has been proposed, it has changed the situation that prior art forms.The dual-heated that its planar heating is uniform and stable, reach decades useful life, have radiation and a conduction because of the emission far ir ray is done usefulness, and energy-saving effect is remarkable, and serviceability temperature can reach 400 ℃, and heats up rapidly, is the replacement ideal product of traditional electrical hot material.

The utility model content

Technical problem to be solved in the utility model is at deficiency right in the prior art, a kind of high-temperature carbon fiber electrothermal paper is provided, this high-temperature carbon fiber electrothermal paper long service life, and heat up rapidly, heat efficiency height, temperature can keep constant at 0-400 ℃, and energy-saving effect is remarkable, having reduced cost, is the replacement ideal product of traditional electrical hot material.

The utility model provides a kind of high-temperature carbon fiber electrothermal paper, soon can be because of the carbon fiber mat (or carbon cloth) of the back heating of switching on stick on the soft insulating material glass fiber mica paper with high temperature adhesive, and looking adhesive character can be from doing or oven dry.Flexible insulating material can also be polyimides, polytetrafluoroethylene etc.After the high-temperature carbon fiber electrothermal paper of making is cut into all size shape on demand, after two ends are with carbon element type high temp conductive adhesive Copper Foil or graphite electrode, draws power supply and both can use.

In the technique scheme, but the high-temperature carbon fiber electrothermal paper is the flexible carbon fiber electrothermal part of cutting, and this carbon fiber electrothermal part can stick on the heat carrier of different shape, can produce heat after energized.

Be provided with insulating barrier between above-mentioned heat carrier and the carbon fiber electrothermal part; This insulating barrier is non-conductive fibre body, pottery or quartz etc. such as glass fiber mica paper, polyimides, polytetrafluoroethylene.

The utility model high-temperature carbon fiber electrothermal paper, planar heating evenly, long service life, because of the emission far ir ray has the dual heat exchange effect of radiation and conduction, can make that the heated material temperature rises rapidly, properties of product stable and temperature is even, high temperature resistant, can in 400 ℃, stablize use, can be under guard mode 500-1200 ℃ of long-term work; Energy conversion efficiency is 100%, utilization efficiency of heat energy is more than 98%, and its power consumption only is about 60% of a traditional product, and energy-saving effect is remarkable, is the regeneration product of thermo electric material.

Because of the utility model add thermally-stabilised rapidly, thereby shorten the working unit time greatly; Because of long product lifecycle, thereby reduce the working unit cost greatly; Because of the product heat efficiency high, thereby save the working unit energy consumption greatly; Because of the broad applicability of the technology of the present invention, numerous new products of can deriving, thus improve the industrial technology level greatly.Therefore no matter the technology of the present invention is the application at industry or civil area product, and all there are great economic benefit and social benefit and environmental benefit in individual, enterprise and country.

Below by drawings and Examples, the technical solution of the utility model is described in further detail.
