summary:

The heating substrate of glass ceramics is mainly composed of glass ceramics carrier. It is composed of multi-layer inorganic color crystal glass glaze coating, inorganic nonmetal far-infrared graphite resistance film and high temperature resistant insulating mica plate. The heating substrate of glass ceramics is made of inorganic ceramics. Glass negative ion material, carbon and other non-metallic conductive materials and infrared radiation materials are compounded on the outer surface of glass-ceramic through printing, high-temperature sintering and other processes, and are permanently integrated with the glass plate carrier to form a layer of inorganic non-metallic far-infrared graphite resistance film. The glass-ceramic heating substrate emits infrared heat after being electrified and heated, forming a heat radiation source for heating.

characteristic:

1. It is made of inorganic ceramics, glass, negative ion, carbon powder and other materials, and there is no open fire when working. No oxidation: the material is environmental friendly, and there is no peculiar smell in production and use. No noise, no harmful gas emissions: it has good waterproof performance, uniform temperature, good impact resistance, not easy to aging characteristics;
   

   
   

2. The heating body is made of carbon and inorganic materials rich in far-infrared, which has strong far-infrared radiation and 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);
   

   
   

3. Using "surface" heating mode, full area heating, low power density, low film temperature, the product can be designed in high and low temperature or multi temperature zone, the temperature difference between high and low can reach 50c;
   

   
   

4. Good cold and hot shock resistance, glass heating plate works under 1.15 times of rated input power until stable state is established. Pour 1 liter of water (water temperature 15C, soil temperature 5C) into a 5mm diameter pipe, and then pour directly to the center of the positive surface of the glass heating plate at a speed of about 10mls. Glass plate is also The glass-ceramic substrate can also be heated to 250c-300c. The 5C cold water can be directly poured into the center of the plate body, and the plate body will not crack after three times of impact;
   

   
   

5. The heater with negative temperature coefficient has no potential safety hazard caused by impulse current;
   

   
   

6. Wooden frame, plastic bracket and various metal brackets can be used as supports, but a certain expansion space and heat dissipation channel must be reserved, and necessary shock absorption and shockproof measures must be taken to prevent damage to products caused by mechanical impact during use and transportation;
   

   
   

7. Because the "R" angle and edge of the glass-ceramic heating substrate are easy to break, the angle should be designed as safe as possible to avoid harm to human body.
