Far-infrared radiant sheet, floor heating system and dome-shaped heating equipment

摘要

Provided is a far-infrared radiant sheet that has less heat unevenness, high heat diffusivity, is extremely effective as a heater, and can realize a heating device that is good for the human body. A far-infrared radiation sheet (1) that is formed in a flat shape and radiates far-infrared rays, and is a heat-generating mixed paper (20) formed by mixing basic materials and carbon fibers, and a heat-generating mixed paper (20). The heat diffusion type mixed paper (10), which is laminated on the heat generating mixed paper (20) and formed by mixing the basic material and carbon fiber or graphite having high thermal conductivity, and the electrode (21) provided in A prepreg (11, 22) and a PET film (23) laminated on a heat-generating mixed paper (20) and a heat-diffusing mixed paper (10) are provided, and far infrared rays are radiated by energizing an electrode (21). To do.
