Abstract

The invention discloses a radio-frequency heating carbon fiber graphitization continuous batching production system and a radio-frequency heating carbon fiber graphitization continuous batching production method for solving the technical problem that fire striking caused by blackening of a quartz tube produces broken wires and burrs to affect the production efficiency. The invention adopts the technical scheme that: a series combination of at least two independent radio-frequency heaters is adopted in the continuous batching production system, the processed carbon fibers pass through the independent radio-frequency heaters in turn, and a multi-gear power output switch is arranged between the radio-frequency heater set and a high-frequency generator; and in the method, a group of radio-frequency heaters are connected in series in the radio-frequency heating carbon fiber graphitization process. The system and the method have the advantages of avoiding the disadvantage that the fire striking caused by the blackening of the quartz tube due to long-time use produces the broken wires and the burrs to affect the production efficiency, avoiding the phenomenon of fire striking and discharge when tar and carbon black attached to the pipe wall after long-time use are contacted with the carbon fibers, improving the industrialized production efficiency and reducing the production cost.

Description

technical field [0001] The invention belongs to the field of radio frequency carbon fiber graphitization production, and relates to a continuous batch production system and method for radio frequency heating carbon fiber graphitization. Background technique [0002] Graphitized carbon fiber is a new material with high quality, high performance, high specific strength and high elastic modulus. The aerospace field has an irreplaceable position. The processing technology of carbon fiber graphitization has made great progress after adopting radio frequency processing, which greatly reduces the energy consumption in the production process, improves the quality, reduces the cost, and is conducive to the promotion of the application range of graphitized carbon fiber. The current radio frequency carbon fiber graphitization production process: the carbon fiber is continuously passed through the coaxial symmetrical magnetic resonance coupling cavity for graphitization treatment under...
