Description

technical field [0001] The invention relates to the field of electric heating elements, more specifically, it relates to a processing technology of a carbon fiber heating tube. Background technique [0002] Electric heating technology using metal materials as heating elements has been widely used in various fields. However, the surface of the metal wire is easily oxidized at high temperature. Due to the continuous thickening of the oxide layer, the effective current passing area is reduced and the current load is increased, so it is easy to burn out. Carbon fiber endows its composite materials with excellent performance due to its inherent characteristics. It has a series of high specific strength, high specific modulus, high temperature resistance, corrosion resistance, fatigue resistance, creep resistance, electrical conductivity, heat transfer and small thermal expansion coefficient. Excellent performance, thus providing possibility and necessity for its application in t...

Problems solved by technology

[0003] The interior of the carbon fiber heating tube processed by traditional processing technology is rod-shaped or bundle-shaped carbon fiber. The outer tube of the same volume can accommodate less heating fibers, the stability is not high, and the service life is short. For this reason, we provide a A carbon fiber heating tube processing technology, so that the carbon fiber heating tube processed by this process can have the advantages of strong stability and long service life.
