Silicon Carbide Heating Plate Far Infrared Heating Plate
Far Infrared Electric Heating Plate
Silicon carbide far infrared electric heater is a radiant heater. After power on, it can form a strong wide-spectrum directional radiation in the vertical space. It effectively converts point energy into far infrared radiation energy, directly transfers it to the object to be dried, quickly converts it into molecular thermal motion, dries from the inside out, achieves the purpose of rapid drying and shaping, and achieves significant energy-saving effects.
Far infrared electric heating plate uses a silicon carbide plate coated with metal oxide, i.e., far infrared coating, as the radiation element. Heating wires are installed in the holes (or grooves) of the element. A thick layer of insulating, refractory, and heat-insulating material is placed at the bottom of the element, and then a metal shell is installed. After connecting the terminals, it can be powered on for use. Silicon carbide has a room temperature flexural strength of 45 MPa, a high-temperature flexural strength of 50 MPa at 1000°C, a bulk density of 2.7-2.75 g/cm³, a thermal expansion rate of 0.42-0.48% at 900°C, and a thermal conductivity (at 350°C) of 10.3-16.7 W/m·K.
When far infrared radiation radiates onto an object, it can be absorbed, reflected, and transmitted. The heated and dried material absorbs far infrared radiation energy at a certain depth inside and on the surface molecules simultaneously, generating a self-heating effect, causing the solvent or water molecules to evaporate, and heating evenly, thereby avoiding deformation and quality change due to different thermal expansion, and keeping the appearance, physical mechanical properties, fastness, and color of the material intact.
Widely used in automobiles, textiles, printing and dyeing, dyes, papermaking, bicycles, refrigerators, washing machines, chemical fibers, ceramics, electrostatic spraying, grain, food, pharmaceuticals, chemicals, tobacco and other industries, achieving ultra-fast drying purposes. Especially suitable for large drying rooms, drying ovens, and continuous drying tunnels.
