Title:
CARBON HEATING ELEMENT AND PRODUCTION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2010/008216
Kind Code:
A2
Abstract:
The present invention relates to a carbon heating element produced from a narrow carbon body obtained by physically braiding a plurality of carbon-fibers without using a synthetic resin solution. More specifically, the present invention provides a carbon heating element and a production method of the carbon heating whichis obtained by: either forming a narrow carbon body by laying a plurality of carbon fibers in a single direction and then braiding them, or forming a narrow carbon body by laying fibers in a single direction, braiding them and then carbonising the resulting narrow fabric; mounting clips for applying electric current to both ends of the shaped carbon body which is obtained by forming the narrow carbon body into a spiral shape; applying a first heat treatment to the shaped carbon body to form a heat-treated, shaped carbon body; applying a second heat treatment to the heat-treated, shaped carbon body to form a carbon coated heating element, on the surface of which a carbon layer having a nanocrystalline structure is vapour-deposited; and applying a third heat treatment to the carbon coated heating element to evaporate off impurities and to convert the remaining amorphous carbon into graphite. The carbon heating element of the present invention has highly uniform heat distribution and resistance characteristics because a narrow carbon body is heat treated without any additional processing, and has an extremely low content of impurities and a sharply extended lifespan because no synthetic resin solution is used in formation of the narrow carbon body and because a third heat treatment is carried out at a high temperature.
