Ceramic heating plate (far-infrared heating plate, radiant heating plate) element structure: It is made of a ceramic material with high emissivity glaze layer with high radiation intensity and good thermal shock performance as the substrate, and high-quality nickel winding heating wire is sintered at one time. The composition of the ceramic heating plate is as follows:
1. Substrate: It is composed of ceramic material with good thermal shock;
2. Heat generation: fired from high-quality Nilu alloy;
3. Glaze layer: It is composed of metal oxide raw materials with good radiation performance at a distance and puts an appropriate amount of additives to increase the radiation intensity and enhance the adaptability of the glaze.
Common specifications of ceramic heating plates: 60*60mm, 60*120mm, 60*240mm, 80*240mm, 85*245mm, 120*120mm, 130*130mm, 100mm*100mm, 200*250mm, 200*300mm, etc., power from 50 -1000W varies. Both voltage 220/380V.
