Description

A carbon fiber heating element

technical field

The utility model relates to the technical field of heating devices, in particular to a carbon fiber heating body.

Background technique

Carbon fiber (CF for short) is a new type of fiber material with high strength and high modulus fibers containing more than 95% carbon. It is formed by stacking organic fibers such as flake graphite microcrystals along the fiber axial direction. It is a microcrystalline graphite material obtained by carbonization and graphitization. Carbon fiber is "soft on the outside and rigid on the inside". It is lighter than metal aluminum, but its strength is higher than that of steel, and it has the characteristics of corrosion resistance and high modulus. It is an important material in national defense and civilian applications. It is a new generation of reinforcing fiber with intrinsic properties and softness and processability of textile fibers.

Carbon fiber can be made by carbonization of polyacrylonitrile fiber, pitch fiber, viscose or phenolic fiber respectively. The more commonly used carbon fiber is mainly polyacrylonitrile carbon fiber and pitch carbon fiber. The manufacture of carbon fibers includes four processes: fiber spinning, thermal stabilization (pre-oxidation), carbonization, and graphitization. The accompanying chemical changes include dehydrogenation, cyclization, pre-oxidation, oxidation, and deoxidation.

Electric heating elements are often used in home floor heating. The existing heating elements are usually printed with ink stripes on the double-layer PET composite film, and then attach electrodes to both sides of the double-layer PET composite film to form a heating element, which is realized by connecting the electrodes to the circuit. The heating pad heats up, and then heats up the entire heating body through the heat conduction of the ink stripes. However, the electrodes of this heating element are easily broken during the laying process, thereby affecting the service life of the heating element.
