Far-infrared silicon carbide heating plate is coated with metal oxide silicon carbide coating that far-infrared radiation component board to do, hole in the component (or tank) put into the electric wire, placed at the bottom of the component thicker insulation, refractory, insulation materials, and then install the metal shell, installed power terminal can be used. Widely used in automotive, textile, printing and dyeing, dye, paper, bicycles, refrigerators, washing machines, chemical fiber, ceramics, electrostatic spraying, grain, food, pharmaceutical, chemical and other industries SiC far-infrared heater is a radiant type heating devices, power and space in the vertical direction to form a very strong broad spectrum of radiation, it is effectively translated into far-infrared energy radiation, delivered directly to the dried material was quickly converted into thermal motion of molecules from the inside out, drying, drying up fast The purpose of dry-shape, and achieve significant energy savings. Silicon carbide at room temperature flexural strength 45Mpa, 1000 ℃ high temperature flexural strength of 50Mpa bulk density 2.7-2.75g/cm3, 900 ℃ thermal conductivity coefficient of thermal expansion 0.42-0.48% (350 ℃) 10.3-16.7w/mk. When the far-infrared radiation to an object on, it can happen absorption, reflection and through. Dry material is heated to a certain depth of the internal and surface molecules absorb infrared radiation, resulting in self-heating effect, so that evaporation of solvent or water molecules, even heating, so as to avoid different levels due to thermal expansion and qualitative change arising from the deformation, so that physical appearance, physical and mechanical properties, fastness and color, etc. intact.
