Advantages and disadvantages of electrical magnesia powder:

Advantages of Electrical Magnesium Oxide:

1. It has good insulation performance and electrical strength.

2. It has good thermal conductivity and can transmit the heat emitted by the electric heating wire to the metal tube.

3. It has good heat resistance and vibration resistance.

Defects of Magnesium Oxide of Electrical Level:

It is easy to absorb carbon dioxide and water in the air, and slightly soluble in pure water. However, after absorbing carbon dioxide, the solubility increases rapidly, and reacts with water to form magnesium hydroxide, which makes the insulation resistance decrease rapidly. Therefore, the electrical insulation performance of the heat pipe filled with magnesia material decreases during storage and use, resulting in electrical breakdown and damage of the heat pipe. In this way, the basic reason why the service life of the electric heat pipe is not long is filled with magnesium oxide.

The solution is: in order to overcome the water absorption of magnesium oxide raw materials, silicon is used to modify the fused magnesium oxide, which is the electrical grade magnesium oxide. Therefore, Magnesium oxide of electrical grade is widely used in the field of electric heat pipe.
