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 role of magnesium oxide powder and magnesium oxide powder? The heating element adopts electric heating wire (electric heating wire), which is composed of metal skin and insulating magnesium oxide powder. The materials of each link are very important. However, if the quality of magnesium oxide powder is not qualified or the installation is not in place, it will directly affect the service life of the heating element. How to correctly install magnesium oxide powder in the heating element can better affect the quality of the heating element.

 

Rules for 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 and must be treated with moisture-proof (magnesium oxide powder modification or heating element sealing treatment) when using it.

 

2. Magnesium oxide powder can be divided into low temperature powder and high temperature powder according to the use temperature range. 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 in a certain ratio (mesh ratio).
