The white magnesium oxide industrial mgo powder, added to the electric heating tube, plays a very significant role in the electric heating tube, like cartridge heater.
The electric heating tube is composed of electric heating wire, metal skin and insulating magnesium oxide powder. If the quality of the magnesium oxide powder is not up to standard or the installation is not in place, it will directly affect the service life of the electric heating tube. The functions of the electric heating tube generally have the following points:
1. Magnesium oxide powder is placed between the heating wire and the tube wall, and is used for insulation between them. At the same time, the magnesium oxide powder has good thermal conductivity. However, magnesium oxide powder has strong hygroscopicity, so it should be treated with moisture-proof when it is used.
2. Magnesium oxide powder can be divided into low temperature powder and high temperature powder according to the temperature range used. Low temperature powder can only be used below 400 degree , and it is generally modified magnesium oxide powder.
3. The magnesium oxide powder is granular, and the magnesium oxide powder used for the electric heating tube is configured by the magnesium oxide powder particles of different thicknesses according to a certain proportion.
