Product Introduction: Yangzhou Sells Meltblown Ceramic Heater
The meltblown fabric ceramic heater is a heater with uniform heat distribution and a thermally conductive metal alloy, ensuring uniform temperature on the heating surface, eliminating hot spots and cold spots in the equipment. It has the advantages of long life, good thermal insulation performance, strong mechanical properties, corrosion resistance, and anti-magnetic field. One type is to cast alloy wire into semiconductor made of quartz glass as raw material. It has the characteristics of high temperature resistance (up to 1200 degrees), corrosion resistance, and beautiful appearance. Widely used in aquarium fish tank heating, high-temperature heating furnaces, semiconductor engineering, glass, ceramics, and wire engineering.
Resistance Heating Ring
It uses the Joule effect of electric current to convert electrical energy into thermal energy to heat objects. It is usually divided into direct resistance heating and indirect resistance heating. In the former, the power supply voltage is directly applied to the heated object. When current flows, the heated object itself generates heat. Objects that can be directly resistance heated must be conductors but have high resistivity. Since the heat is generated inside the heated object itself, it is internal heating with high thermal efficiency. Indirect resistance heating requires special alloy materials or non-metallic materials to make heating elements, which generate heat and transfer it to the heated object through radiation, convection, and conduction. Since the heated object and the heating element are separated, the type of heated object is generally not limited, and operation is simple.
The materials used for the heating elements of indirect resistance heating generally require high resistivity, small temperature coefficient of resistance, small deformation at high temperatures, and not easy to embrittle. Commonly used are metal materials such as iron-chromium-aluminum alloy and nickel-chromium alloy, and non-metallic materials such as silicon carbide and molybdenum disilicide. The working temperature of metal heating elements can reach 1000-1500°C depending on the material type; the working temperature of non-metallic heating elements can reach 1500-1700°C. The latter is easy to install and can be replaced while the furnace is hot, but it requires a voltage regulating device during operation and has a shorter lifespan than alloy heating elements. It is generally used in high-temperature furnaces, places where the temperature exceeds the allowable working temperature of metal heating elements, and some special occasions.
