Tungsten wire does require some special protective measures when in use, which are designed to extend the service life of tungsten wire, improve its performance stability, and ensure safe use. The following is a detailed summary of these special protective measures:
- Gas environment control
Vacuum or inert gas protection:
When used at high temperature or in a specific environment, the tungsten wire should be placed in a vacuum or inert gas (such as nitrogen, argon) environment to avoid reaction with oxygen in the air, resulting in oxidation and performance degradation.
Reduce oxygen concentration:
Increasing the concentration of hydrogen in the working area while reducing the concentration of oxygen can reduce the risk of tungsten wire oxidation.
- Surface coating protection
Tungsten wire protective agent:
Using tungsten wire protective agents containing elements such as silicon, calcium, potassium, and magnesium, a protective film can be formed on the surface of the tungsten wire to prevent oxidation. This protective film can remain stable under high temperature and pressure, which helps to extend the service life of the tungsten wire.
Anodizing:
During the manufacturing process of tungsten wire, anodizing can be performed to form an oxide film on the surface of the tungsten wire. This oxide film can protect the tungsten filament from oxidation, improve its corrosion resistance and service life.
- Current and voltage control
Current control:
By controlling the current of the bulb, overload and battery overdischarge can be avoided, and the tungsten filament lamp can be prevented from overheating and melting. During use, the current should be observed and adjusted regularly to ensure that it is within the appropriate range.
Voltage control:
Using the appropriate voltage can ensure that the tungsten filament operates under normal working load, avoiding performance degradation and shortened life caused by excessively high or low voltage.
- Keep clean and dry
Regular cleaning:
Tungsten filaments are easily contaminated with dust, grease and other impurities during use, which may affect their electrical conductivity and heat dissipation. Therefore, the tungsten filament needs to be cleaned regularly to keep its surface clean.
Keep dry:
Excessive humidity will accelerate the oxidation process of tungsten filaments and reduce their performance. Therefore, during use and storage, the tungsten filament should be kept in a dry environment.
- Other protective measures
Avoid physical damage:
During installation, replacement or use, physical damage to the tungsten filament, such as scratches and impacts, should be avoided. These damages may cause the tungsten filament to break or degrade in performance.
Choose the right type and specification of bulb:
According to the specific application scenario and needs, choose the right type and specification of bulb to ensure that the tungsten filament can work in the best condition.
