Features: 1.Carbon crystal floor mats are winter office work, the gospel of the players! With her, you will have a warm winter. 2.Carbon crystal, the full name of carbon crystallite, is a crystal structure of carbon. Carbon crystal electric heating products have many advantages, controllable heating temperature and less waste; regular heating, can quickly heat up; operability is strong, use electric energy and other clean energy, no pollution. 3.Due to the many advantages of carbon crystals, such as energy saving, environmental protection and safety, carbon crystal technology has a wide application prospect. Heating can replace traditional heating methods with high energy consumption, high pollution and high waste. 4.Working principle: Under the action of electric field, the carbon crystal molecules undergo Brownian motion and friction heating; the carbon crystal heating film is a large-area planar heating material, and even if the carbon crystal heating film is broken down, it will not leak electricity and affect heat generation. 5.The carbon crystal heating film has a service life of more than 100,000 hours, which is basically equivalent to a building.
