Product Introduction: Yangzhou Selling Melt-blown Ceramic Heater
The melt-blown fabric ceramic heater is a heater with uniform heat distribution, using thermally conductive metal alloys to ensure uniform temperature on the heating surface, eliminating hot spots and cold spots in the equipment. It has advantages such as long lifespan, good thermal insulation, strong mechanical properties, corrosion resistance, and anti-magnetic field. One type is made by casting alloy wire into semiconductor material with quartz glass as the raw material. It has the characteristics of high temperature resistance (up to 1200 degrees), anti-corrosion, and aesthetics. Widely used in aquarium fish tank heating, high-temperature heating furnaces, semiconductor engineering, glass, ceramics, and wire engineering.
Resistance heating coil
Utilizes the Joule effect of electric current to convert electrical energy into thermal energy to heat objects. Usually divided into direct resistance heating and indirect resistance heating. In the former, the power supply voltage is directly applied to the heated object, and when current flows through, the heated object itself generates heat. Objects that can be directly resistance heated must be conductors but with high resistivity. Since heat is generated within 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 thermal energy and transfer it to the heated object through radiation, convection, and conduction. Since the heated object and the heating element are two separate parts, the type of heated object is generally not limited, and operation is simple.
The materials used for heating elements in indirect resistance heating generally require high resistivity, low temperature coefficient of resistance, minimal deformation at high temperatures, and resistance to embrittlement. Commonly used metal materials include iron-chromium-aluminum alloys and nickel-chromium alloys, and non-metallic materials include silicon carbide and molybdenum disilicide. The working temperature of metal heating elements can reach 1000-1500°C depending on the material type; non-metallic heating elements can reach 1500-1700°C. The latter is easy to install and can be replaced while 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 temperatures exceed the allowable working temperature of metal heating elements, and certain special occasions.
