How to choose the suitable magnesium powder for heating elements
In the manufacturing of electric heating elements, the selection of magnesium powder (MgO powder) is crucial to ensure the performance and durability of the element.
Different working temperature ranges require the use of different types of magnesium powder.
- Low-temperature applications (operating temperature ≤ 400℃):
Low-temperature magnesium powder should be used.
Silicone oil-treated low-temperature magnesium oxide powder is mainly used for low-load electric and non-high-demand liquid heating elements.
Due to its excellent moisture-proof properties, the manufactured electric heating element does not require dehumidification and sealing.
- Medium temperature application (400℃ < operating temperature ≤ 600℃):
Medium-temperature MgO powder is suitable.
Medium and low-temperature magnesium powder treated with silicone oil suits low-load electric and liquid heating elements with high-performance requirements.
This heating element also eliminates dehumidification and sealing due to its excellent moisture resistance.
- High-temperature applications (operating temperature > 600℃):
High-temperature magnesium oxide powder needs to be used.
High-temperature magnesium oxide powder is mainly used to manufacture medium to high-load air heating electric heating elements, which can withstand heat treatment up to 1050°C.
Electric heating elements used in high-temperature applications must be drained of moisture promptly and tightly sealed to maintain efficiency and longevity.
Evaluate purity levels: Higher-purity magnesium oxide performs better but may cost more. Particle size and composition: Finer particles generally provide better thermal conductivity and insulation.
How to store magnesium oxide powder
- Storage conditions:Store in a cool, dry place to prevent moisture absorption.
- Packaging:Ensure packaging is airtight to maintain purity.
- Shelf life management:Rotate inventory regularly, using older supplies first, as magnesium oxide deteriorates.
Recommended storage and usage time limits for magnesium oxide (MgO)
hydroxide (Mg(OH)₂) during storage. This conversion process accelerates with time, resulting in a decrease in its active content. Therefore, magnesium oxide should be stored as quickly as possible.
- Avoid buying in bulk:
Long-term storage reduces the effectiveness of magnesium oxide and may also cause a waste of resources.
Purchasing based on short-term needs is recommended to ensure the freshness and activity of magnesium oxide.
- Usage time limit:
Ideally, magnesium oxide should be used within half a month of purchase.
If conditions permit, use it within a month to maintain optimal performance.
- Proper planning:
Reasonably planning the purchase amount of magnesium oxide based on actual demand can effectively avoid unnecessary waste.
Check your inventory regularly to ensure your magnesium oxide remains in optimal condition.
How to deal with damp magnesium oxide powder
- assess safety:
Before handling, ensure safety first. Magnesium oxide powder may be exothermic if mixed with water, so direct contact with skin or eyes should be avoided. Make sure the work area is well-ventilated to prevent dust inhalation.
- Drying process:
Sprinkle the moist magnesium oxide powder onto a dry surface to distribute it evenly.
Use low-temperature drying methods, such as low heat in a dryer or air drying in a well-ventilated area.
Turn the powder regularly to ensure even drying.
- Screening and Assessment:
Once dry, use a sieve to remove any clumps or impurities.
Check the quality of the powder to confirm that it has not undergone chemical changes. If necessary, perform small-scale performance testing.
The dried magnesium oxide powder should be stored in a dry, sealed container to avoid getting damp again.
- Disposal suggestions:
Safe disposal should be considered if the dried magnesium oxide powder cannot be restored to satisfactory quality standards.
Follow local regulations and guidelines for disposal.
Always consider safety and quality assurance when handling damp electrical grade magnesium oxide powder. If powder quality is severely compromised, the safest option may be to replace rather than attempt to restore.
