It belongs to moisture-proof and high-temperature-resistant magnesium oxide. It is divided into different grades and specifications according to various electrical performance requirements. It is suitable for the production of different high-temperature air-fired electric heating elements. It can withstand an air-fire temperature of up to 800 degrees Celsius and is not suitable for high-temperature heat treatment (such as 1050℃annealing). With the property of strong moisture-proof ability and can be easily sealed. Before sealing, the heating element needs to be dried at 200℃-350℃/2-4 hours.
Scope of Application:
Applicable to various medium power and medium to high rate load medium heaters such as water heater tubes, oven heating tubes, coil heating tubes, etc.
Improper use of magnesium powder will lead to instability in the use of electric heating tubes, so how to avoid this phenomenon?
1. Pay attention to the matching of magnesium powder according to an appropriate ratio to avoid the phenomenon that the coarse sand and fine sand seriously exceed the standard.
2. The sieve phenomenon of different mesh grit appears during the transportation of the electric heating tube products, and they must be re-mixed to ensure the flow rate before use.
3. The effect of the moisture resistance of the anti-moisture agent on the flow rate.
Safety and Storage:
Magnesium oxide powder is non-toxic and has a small amount of dust. It is recommended to wear masks and gloves during use. The product should be stored in a dry place, it is recommended to use it within 12 months after production.
