Problems solved by technology

At present, the far-infrared heating film in the prior art and the heating equipment made of it all have the following deficiencies due to the limitations of materials and processes: 1. The electrothermal conversion rate is low, and the electric energy cannot be fully utilized, which wastes energy; 2. The emission of infrared rays is unstable, and the wavelength of far-infrared rays cannot be stabilized in the most beneficial wave band for human health, so it cannot play a role in health care; three, the hardness is too high, it is difficult to fold, making storage and transportation difficult; four, it cannot Random cutting, fixed size, small application range; five, prone to current leakage, easy to generate static electricity and sparks, low safety performance
