The role of magnesium oxide powder in the electric heating tube.
1, in the electric heating wire and electric heating tube between the role of insulation.
2, to conduct the heat emitted by the electric heating wire to the electric heating tube shell.
3, used to fix the electric heating wire space position.
From here we can learn that the surface of the electric heating tube is not charged, the reason also lies in the insulating effect played by the magnesium oxide powder.
Magnesium oxide powder according to the different working temperature selection of different temperature-resistant magnesium oxide powder, can be divided into low temperature powder, medium temperature powder, high temperature powder and other types, the choice of filler material will directly affect the price of electric heating tube and life. This is the reason why a penny a penny. Magnesium powder from a few thousand a ton to tens of thousands of a ton are available, the main difference with the insulation performance and temperature resistance.
From this point can also be seen, the same size specifications of the heating tube, in the case of the same tube material, the price will also have a certain error.
