summary:

Mica heating substrate is mainly composed of mica plate carrier. Inorganic nonmetal far infrared graphite resistance film. South high temperature insulating mica cover plate and metal edge strip. Mica heating substrate is made of inorganic ceramic and glass materials. The negative ion material, sulfur and other non-metallic conductive materials and infrared radiation materials are compounded on the outer surface of the mica substrate by printing, high-temperature sintering and other processes, and are permanently made into an integral surface with the mica substrate to form a layer of inorganic non all far-infrared graphite electric film, and the surface is covered with mica juekun sheet. The peripheral part is wrapped with all parts to form an integral component.

characteristic:

1. Surface heat source. Planar radiation heating. The thermal field is uniform. The heating uniformity can reach 85%. Compared with the traditional linear wire electric heating element, it provides more uniform thermal field, shorter heating time, faster response time and lower power load;
   

   
   

2. Production of inorganic materials. Stable performance. Small enthusiasm, no open fire, no oxidation. In working state and storage and transportation state. No change in electrical performance: environmental protection materials, no peculiar smell in production and use. No noise, no harmful gas emissions;
   

   
   

3. The heating material consists of carbon and inorganic ceramics rich in far infrared. It is made of glass and has strong far-infrared radiation, which is beneficial to human health (the main wavelength range of far-infrared is 8-15 μ m, which is called "health light" and "life light" in medical circles);
   

   
   

4. Using "surface" heating mode, full area heating, low power density, low film temperature, in the same functional area. The temperature difference between high and low temperature is only 5C, the product can be designed in high and low temperature zone, and the temperature difference between high and low temperature can reach 30C;
   

   
   

5. Negative temperature coefficient heater has no safety benefit brought by impulse current.
