High-temperature baking ceramic heating element (MCH) is directly in the AL2O3 alumina ceramic billet printed resistance paste, baked at a high temperature of about 1600 ℃, and then by the electrode, the lead is processed by a new generation of low-temperature heating element. Is following the alloy electric wire, PTC heating element after a new generation of new products, widely used in daily life, industrial and agricultural technology, communications, medical, environmental protection, and other needs of low-temperature heating in many areas. In the household electric heating appliances: such as small warm wind ambient, hairdryer, dryer, heater, cold and warm cell phone, dryer, electric splint, electric iron, electric iron, hair straightener, curling iron, electronic thermos flasks, insulation cabinets, electric cooking utensils, toilet ceramic heaters, water heaters, etc.; in the industrial sector, such as industrial baking equipment, electric bonding, water, oil and acid-alkali liquid heaters, etc.; in the electronics industry, such as In the electronics industry, such as small special crystal device thermostat tank; in the medical field, such as infrared physical therapy equipment, intravenous injection heater and so on.
