Carbon Fiber Heating Cable

Carbon fiber is a new type of high-performance fiber-reinforced material with excellent properties such as high strength, high modulus, high temperature resistance, wear resistance, fatigue resistance, corrosion resistance, creep resistance, conductivity, and thermal conductivity. It can reduce the weight of components, thereby improving their technical performance. Therefore, using carbon fiber as an electric heating element has many excellent properties that cannot be compared to metal, PTC and other electric heating elements: 1. Rapid heating up Capable of producing the life light required by the human body, far-infrared radiation ranging from 8 μ m to 15 μ m.   2. High efficiency of electric thermal conversion, saving energy Floor infrared heating wire is a type of all black body material, with an electric heating conversion efficiency that is 30% higher than metal heating, and an electric heating efficiency of about 100%.   3. High tensile strength Under the same allowable current load area, the strength of carbon fiber is 6-10 times higher than that of metal wire, and it will not break during use, so the tensile strength does not change much during the electric heating process.   4. No arcing due to broken wires Effectively prevent the occurrence of fires.   5. Lightweight Effectively reducing the weight of components, thereby improving their technical performance.   6. Stable chemical properties Corrosion resistant and not easily oxidized. When heated to 3000 degrees Celsius in an anaerobic state, its mechanical properties do not change, and it overcomes the limitations of metal wires in an electric heating state PTC、 The disadvantage of low strength and easy oxidation and burning of silicon carbide heating elements.   7. Long service life Carbon fiber electric heating wire have the same lifespan as buildings.

Temperature High temperature environment: Prolonged exposure to high temperatures can accelerate the aging of the insulation material of the electric heating wire. At the same time, high temperature will increase the resistance of the electric heating wire, which leads to more heat generation, further accelerating the damage of the electric heating wire and shortening its service life. Low temperature environment: Under low temperature conditions, the flexibility of the electric heating wire will decrease and become more prone to breakage. For example, for electric heating wires used outdoors in cold weather, if appropriate insulation measures are not taken, the insulation layer is prone to rupture when subjected to external tension or bending, thereby affecting the performance and service life of the electric heating wire. Humidity Frequent changes in humidity: Frequent changes in environmental humidity can cause the insulation material of the electric hotlines to expand and contract. For example, when the humidity increases, the insulation material absorbs moisture and expands; When the humidity decreases, it will lose water and shrink again. This repeated expansion and contraction can cause stress inside the insulation material, which over time can lead to cracks and delamination in the insulation material, damaging its insulation performance and affecting the service life of the electric heating wire. Chemical substances: In environments with corrosive chemicals such as acid, alkali, salt, etc., the metal wires and insulation materials of electric heating wires will be corroded. For example, acidic substances can react chemically with metal wires, causing rust and corrosion on the metal surface, resulting in a decrease in the conductivity of the wire and an increase in resistance. At the same time, corrosive substances can also damage the structure of insulation materials, making them fragile and losing their insulation protection function, thereby shortening the service life of electric heating wires. Mechanical stress: If the heating wire is in an environment that is susceptible to mechanical vibration, impact, or tension, it can cause damage to it. For example, in some industrial equipment, the electric heating wire may vibrate with the operation of the equipment, and long-term vibration can cause fatigue fracture of the wires inside the electric heating wire. In addition, when the electric heating wire is stretched or squeezed by external forces, it will cause deformation of the internal structure, resulting in poor contact between the wires, increased resistance, and thus affecting the heating effect and service life of the electric heating wire.
