It does not generate light energy and mechanical energy, and has no self-heat loss. The electrothermal conversion efficiency is as high as 98%, and the heat generated mainly depends on radiation transfer. , its electric-thermal radiation conversion efficiency is not less than 70%, and the normal total emissivity is 85%. Compared with traditional conduction heating or convection heating, it can achieve the same effect and save energy by about 30%. Far-infrared non-metallic heating plate In the environment of energy saving, emission reduction and environmental protection, many large chemical companies at home and abroad are replacing heat transfer oil and steam heating with far infrared heating. The products are widely used in automobiles, textiles, printing and dyeing, dyes, papermaking, bicycles, refrigerators, Washing machine, chemical fiber, ceramics, electrostatic spraying, grain, food, pharmaceutical, chemical industry, tobacco and other industries, to achieve the purpose of ultra-fast drying and heating, especially suitable for chemical reaction kettles, large drying rooms for leather machinery, ovens, flowing water drying channels, etc. Scenario. At present, far-infrared non-metallic heating plates on the market are prepared by thermal spraying tin dioxide or other oxides. The manufacturing cost is relatively high, and the rate of defective products is high. At the same time, there are serious pollution. Therefore, the design Go out a kind of manufacture method that contains the far-infrared heating plate of single, multi-layer graphene material, be urgently needed for current heating plate technical field
