These consumer electronics are using MCH ceramic heat generators
MCH is the abbreviation of metal-ceramic heating element. It adopts high-temperature co-fired multi-layer ceramic technology to print heating resistor slurry on the cast body (zirconia, alumina ceramic or zirconia toughened alumina ceramic, etc.), and then more The layers are laminated, and the heating circuit is built into the ceramic material, which is sintered at about 1650 degrees to make it integrated, and the ceramic body plays the role of protection and insulation. The cermet heating element has no open flame, corrosion resistance, high temperature resistance, long service life, high efficiency and energy saving, stable and uniform, and fast thermal compensation. The product does not contain lead, mercury, hexavalent chromium and other harmful substances, and can fully meet the EU environmental protection requirements.
Metal-ceramic heating elements and PTC semiconductor ceramics are commonly used ceramic heater materials. Compared with PTC ceramic heaters, they can save 20 to 30% of electric energy under the same heating effect, have high heating efficiency and are more energy-saving. Moreover, they can be used for a long time without power degradation. The temperature of the MCH ceramic heater rises rapidly. When energized, the surface of the heater can reach 200 degrees in 10s, 800 degrees in 30s, and 500-700 degrees in long-term use.
In consumer electronics, there are a variety of functions that require heated components. Due to the many advantages of cermet heating elements, this material is currently used in many consumer electronics products. Next, the editor collected and sorted out the application of MCH ceramic heaters under the current trend of consumer electronics explosion.
1. Smart toilet heater: Compared with ordinary toilets, smart toilets have multiple functions such as heating the toilet lid, washing with warm water, drying with warm air, and sterilizing. The penetration rate of smart toilets in our country is not high, but in Japan, no matter how small the toilet is, it needs to be equipped with a smart toilet. But slowly, feeling the comfort of smart toilets, smart toilets have become an important option for house decoration, and more and more friends have smart toilets. In smart toilet products, the heating module is an important part. With it, the cold toilet can also become "warm".
2. Portable drinking cup: "Drink more hot water" is also the essence of Chinese culture. It is the Chinese who love to drink hot water on earth, no one will have an opinion. A cup of hot water can solve a thousand problems, but you have to drink hot water to be healthy. Kettles of unknown purpose when away from home, in hotels, or in villages where there are no kettles, but people who love to drink hot water tend to be very, very frustrated.
3. Electric cooking lunch box: "Healthy eating", similar to healthy drinking, has become the key pursuit of workers, and the MCH ceramic heating element allows you to eat hot meals faster.
The above are just some application descriptions. There are many types of consumer electronics, especially the housing market economy brought about by the epidemic, and the consumption of consumer electronics is growing rapidly. If you want to tap the potential of more consumer electronics, you can learn more about it.
