MCH stands for Metal Ceramic Heaters MCH stands for Metal Ceramic Heaters
MCH is the abbreviation of metal ceramic heating element, that is, metal ceramic heating element. Using high-temperature co-combustion multilayer ceramic technology, printing heating resistor paste (tungsten, molybdenum, manganese, silver, palladium) on the flowing billet (zirconia, alumina ceramics or zirconia toughened alumina ceramics, etc.) according to the design requirements of the heating circuit High-melting metals), and then built multi-layer superimposed heating wires in the ceramic material, sintered at about 1650 ° C, and the ceramic body plays the role of protection and insulation. The heating body has no open flame, corrosion resistance, high temperature resistance, long service life, energy saving and high efficiency, stable and uniform, and fast thermal compensation. This product does not contain harmful substances such as lead, mercury, hexavalent chromium, etc., and fully meets the environmental protection requirements of the European Union.
MCH ceramic heating elements, plates, rods and tubes.
Synonyms: MCH heater, MCH ceramic heater, cermet heater, HTCC ceramic heater, HTCC ceramic heater.
MCH ceramic heating body and PTC semiconductor ceramic are common ceramic heating body materials. Compared with the PTC ceramic heating element, under the same heating effect, it can save 20~30% of electric energy, has high heating efficiency (up to 98.6%), saves more energy, and has no power attenuation after long-term use. The heating body of the MCH ceramic heater rises rapidly. When energized, the surface of the heating plate can reach 200°C within 10 seconds, and can rise to 800°C within 30 seconds, and the long-term use temperature can reach 500-700°C (the maximum temperature of the practical PTC heating material is 300°C), energy saving and long service
life , High reliability ~.
In the field of consumer electronics, since MCH ceramic heaters have many commendable advantages, there are various functions to realize heating components. Currently, the material is used in many consumer electronic devices.
