Carbon Fiber Heating Wire

The reason why heating cable heating is called the most ideal heating method in winter is not only because of its economy, safety, convenience, and high quality, but also because it regards people as the main body of life, highlighting the three modern life themes of comfort, health, and environmental protection; Highly humanized design, simple and flexible control methods, bring great convenience to users; The system structure hidden underground maximizes the saving of indoor space. Comfortable physical sensation： The heating cable heating system mainly relies on far-infrared radiation for heat transfer (accounting for more than 60% of the total heat transfer), and its radiation principle is the same as that of solar radiation. The ways of heat transfer are divided into three forms: convection, conduction, and radiation. Radiant heat is the most comfortable way of heat transfer for the human body, giving people a warm feeling like sunshine without air flow or dryness. People can set the most suitable indoor temperature according to their own needs, which is not affected by outdoor temperature or seasonal restrictions, and always maintains a warm and spring like feeling indoors. Having health functions： Due to the use of the ground as a heat dissipation surface, heat is transferred from bottom to top, giving people a feeling of warmth and coolness. According to medical principles, the most comfortable temperature for human foot sensation is 29 ℃, and the most comfortable temperature for head sensation is 18 ℃. The environmental temperature created by the heating cable heating system is exactly in line with the physiological needs of the human body, which is very beneficial to human health. At the same time, far-infrared radiation has health benefits for the human body, making it the most scientific heating method.

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.

1. Raw material costs Carbon fiber quality: The quality of carbon fiber is one of the key factors determining its price. High quality carbon fiber has higher strength, better conductivity, and thermal stability. The heating wires produced by well-known carbon fiber brands are relatively expensive because these carbon fibers perform well in terms of raw material purity, uniformity of fiber bundles, etc., ensuring excellent and stable performance of the heating wires.    Auxiliary materials: In addition to the carbon fiber body, auxiliary materials such as insulation layer and sheath of the heating wire will also affect the price. High quality insulation materials, such as fluoroplastics (PTFE), polyvinyl chloride (PVC), etc., have good electrical insulation, high temperature resistance, and corrosion resistance, which can improve the safety and service life of heating wires, but the cost is also high. For example, the price of carbon fiber heating wires using high-performance fluoroplastics as insulation layers will be higher than that of ordinary PVC insulated heating wires.   2. Production process Manufacturing accuracy: High precision manufacturing processes can ensure consistent performance of carbon fiber heating wires. For example, in the winding and weaving process of carbon fiber filaments, if the technology is advanced and the precision is high, it can make the resistance of the heating wire uniform and the heating efficiency stable. By adopting advanced automated production equipment and precise manufacturing processes, the price of the produced heating wire will correspondingly increase, as these processes can effectively reduce the rate of defective products and improve product quality.   The complexity of the production process: If the production process involves special processing steps, such as surface modification of carbon fibers, manufacturing of multi-layer composite structures, etc., it will increase production costs and thus affect prices. For example, carbon fiber heating wires that have undergone special surface treatment can enhance the bonding strength between carbon fiber and other materials, improve the overall performance of the heating wire, but this additional treatment process will increase the price. 3. Power and specifications Power size: Generally speaking, carbon fiber heating wires with higher power have relatively higher prices. This is because high-power heating wires require the use of more carbon fiber materials, and in the design and manufacturing process, many factors such as heat dissipation and safety need to be considered, resulting in higher requirements for technology and materials. For example, high-power carbon fiber heating wires used for industrial heating (such as those with a power of over 1000W) are more expensive than ordinary household heating wires with lower power (such as 100-500W).   Length and wire diameter specifications: Carbon fiber heating wires with different length and wire diameter specifications have different prices. A longer heating wire naturally has a higher price, while a thicker wire diameter usually means higher heating efficiency and carrying capacity, and the price will correspondingly increase. For example, a carbon fiber heating wire with a diameter of 6mm will be more expensive than a similar heating wire with a diameter of 3mm.   4. Application areas and market demand Market supply and demand relationship: When the demand for far infrared heating cable in the market exceeds the supply, prices often rise; On the contrary, prices may decrease. For example, during the peak season of winter heating demand, the market demand for carbon fiber underfloor heating lines increases significantly. If the supply is relatively tight, the price will rise. In some off-season or emerging application areas where market demand has not yet fully opened up, prices may remain relatively stable or decrease to stimulate market demand.
