The Role Of Magnesium Oxide In Heating Elements
Magnesium oxide powder is no stranger to us or you. It plays a decisive role in the heating element, but how much do you know about the effect of magnesium oxide powder and magnesium oxide powder? The heating element is made of electric heating wire (heating wire), It is composed of metal skin and insulating magnesium oxide powder. The material of each link is very important. However, if the quality of the magnesium oxide powder is unqualified or the installation is not in place, it will directly affect the service life of the heating element. How to correctly install the magnesium oxide powder in the heating element can better lead to the quality of the heating element.
The rules of magnesium oxide in heating elements:
1. Magnesium oxide powder is located between the heating wire and the tube wall, and is used for insulation between the heating wire and the tube wall. At the same time, magnesium oxide powder has good thermal conductivity. However, magnesium oxide
The powder has strong hygroscopicity, so it must be treated with moisture-proof (magnesium oxide powder modification or heating element sealing treatment) during use.
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°C, generally modified oxygen
Magnesium powder.
3. Magnesium oxide powder is granular, and the magnesium oxide powder in the heating element is made of magnesium oxide powder particles of different thicknesses according to a certain ratio (mesh ratio).
