Magnesium powder sleeve refers to an accessory for making cartridge heater. The conventional cartridge heating element is filled with magnesium powder, but the production process of single head heating pipe is different, and it is filled with magnesium powder sleeve + magnesium.

Some precautions for the use of magnesium in cartridge heater: 1. The magnesia powder is located between the electric heating wire and the pipe wall, which is used for the insulation between the electric heating wire and the pipe wall. Together, magnesia powder has outstanding heat conduction function. However, magnesia powder has a strong hygroscopicity, so it should be treated with moisture-proof treatment when it is used. 2. According to the temperature scale of application, magnesia powder can be divided into two kinds: low temperature powder and high temperature powder. Low temperature powder can only be used below 400 ℃, usually through modified magnesia powder. 3. The magnesia powder is granular. The magnesia powder used in the electric heating tube is made of different thickness magnesia powder particles according to a certain proportion (mesh ratio). Therefore, it is also important to select suitable magnesia powder to increase, and even increase is also very important.
