Far infrared silicon carbide electric heating plate

It uses a silicon carbide plate coated with metal oxide, that is, far-infrared paint, as a radiating element. An electric heating wire is installed in the element hole (or slot), and a thicker insulating, fire-resistant, and heat-insulating material is placed at the bottom of the element. Then install the metal casing, install the binding posts, and then it can be powered on.
When far-infrared rays radiate to an object, absorption, reflection and transmission can occur. The heated and dried substance absorbs far-infrared radiation energy at a certain depth inside and on the surface molecules at the same time, producing a self-heating effect, causing the solvent or water molecules to evaporate and generate heat evenly, thereby avoiding deformation and qualitative changes due to different degrees of thermal expansion. Material appearance, physical and mechanical properties, fastness and color remain intact.
Because silicon carbide far-infrared electric heating plates have the advantages of good radiation effect, significant power saving, and convenient use and maintenance, they occupy a considerable proportion in drying and heating. Especially suitable for large drying rooms, ovens and flowing water drying tunnels.

In recent years, materials with far-infrared radiation have also been sintered and formed to replace metal plates or covers. This kind of element is safer and more reliable than the former, and has higher radiant energy. manufacturers of far-infrared electric heating panels also call it far-infrared radiation heaters.
Far-infrared radiation heaters are divided into structural shapes, including plate, tube and lamp shapes.
The substrates of plate-shaped far-infrared radiation heaters are divided into three categories: ceramics, metals and glass-ceramics. At present, ceramics are widely used in China, and the most widely used ones are ceramics based on silicon carbide.
The silicon carbide substrate in the plate-shaped far-infrared heater is a plate-shaped device whose surface is coated with a far-infrared radiation coating.
