Development background of thick film MCH electric heating elements

- Aug 05, 2020-

With the progress of the times, people's pursuit of products and the environment has become more extreme. In the current electronic market, ceramic heating components will be products that people commonly demand. The thick film circuit for MCH ceramic heating is mainly to replace the most widely used alloy wire heating elements and PTC heating elements and components. At present, the thick film type MCH electric heating thick film circuit we developed has been wMCHidely used in electric heaters, hair straighteners, electric water cups, ultrasonic instruments, precision instruments, hand dryers, instant water heaters, multi-function microwave ovens, ovens and other household appliances and Industrial equipment and electrical appliances such as mold heating, tin melting furnace heating, injection molding machine, etc. MCH is the abbreviation of MetM Ceramics Heater, which refers to a ceramic heating element made by printing a metal (now more commonly used tungsten paste) heating layer on a ceramic base layer and then co-sintering at a temperature above 1600°C. It has corrosion resistance, high temperature resistance and long life. , High efficiency, energy saving, uniform temperature, good thermal conductivity, fast thermal compensation, etc., and it does not contain harmful substances such as lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers, etc., and meets the EU RoS and other environmental protection requirements. When the MCH is energized, the temperature can rise to 800 oC in 30 seconds. Based on the excellent performance of MCH, it is widely used in medical equipment, machinery and electronics industries. At the same time, MCH also has the advantages of no noise and no harmful substances during work. It emits infrared rays that are beneficial to the human body during work. It is a new type of environmentally friendly electric heating element. Our company has a complete set of thick film resistor production and testing equipment. On this basis, our company has carried out the development and production of thick film MCH electric heating elements. After a period of trial production, a set of high-quality and efficient thick film The production process of the membrane type MCH electric heating element can meet the needs of the market and can guide the production.
