1. The flexible electric heating sheet has the characteristics of high heating efficiency, reliable structure, safe use, soft texture, convenient and durable, and is suitable for heating pipes, oil drums or bathtubs. It overcomes the existing soft electric heating of PET and has a low temperature and easy The aging cracks and the hard texture of the carbon fiber paper hard electric heating plate are disadvantages of being inconvenient to use;
2. The black ceramic layer wrapped on the outer wall of the heating wire can make the heat radiation coefficient of the heating wire reach 0.95. Therefore, under the same temperature heating condition, the surface temperature of the heating wire should be lower, thereby further improving the use of the heating wire. life.
