At present, the traditional heater represented by metal alloy wire is widely used in the household appliances like oven. Although the production cost of this material is controllable and easy to obtain, it has long response time and slow temperature rise. As a new two-dimensional carbon material, graphite sheet has excellent electrical and thermal conductivity. It is the carbon material with the highest thermal conductivity so far. It is very suitable to be used as the heating tube material of household appliances.


The graphite heating tube breaks through two major technological bottlenecks, and there is no need to worry about the slow heating of the oven heating tube.

Compared with traditional quartz baking tubes, graphite baking tubes are lighter, have less thermal inertia, and heat faster. The preheating time is only 0.2 seconds, and their reaction speed is comprehensively increased by 115 times. The meticulously improved baking tube structure achieves "strong penetration" of heat conduction, increasing the penetration rate by 36%. While considering heating uniformity, the temperature of the heating body can reach 1300 ℃, bringing stronger thermal radiation and shortwave penetration efficiency, so that the food can be heated up quickly. Through technical processing, the power of graphite baking tubes is distributed at both ends of the heating body, improving the power density per unit length. Compared with ordinary heating tubes, graphite sheets, known as "black gold", have strong thermal conductivity. When applied to an oven, its heating speed is 115 times that of a regular quartz tube oven. It does not require preheating and can be directly baked.
