The application of tungsten wire in firefighting equipment is mainly reflected in the following aspects:
- Reinforcement material in fireproof fabrics
Enhanced fireproof performance: Tungsten wire has an extremely high melting point (about 3422°C), which is much higher than the melting point of most other materials. This allows tungsten wire to maintain stability in high temperature environments and is not easy to melt or deform, thereby improving the overall fire resistance of fireproof fabrics.
Provide excellent heat resistance: Tungsten wire can withstand high temperatures without losing its physical properties. Therefore, tungsten wire-reinforced fireproof fabrics perform well in high temperature environments, such as fire, thermal radiation or high temperature industrial environments, and can effectively protect the wearer from thermal damage.
Enhance the mechanical strength of the fabric: The high strength of tungsten filaments makes fireproof fabrics more durable and able to withstand physical impact and wear while maintaining their fireproof function. The high strength and high toughness of tungsten filaments help fireproof fabrics maintain their structural integrity in harsh environments.
Improve the resistance of fabrics to melting: Since tungsten filaments do not melt at high temperatures, this allows fireproof fabrics to resist direct contact with flames without being melted, further improving fire protection capabilities.
Reduce thermal conductivity: The thermal conductivity of tungsten filaments is relatively low, which can effectively isolate heat conduction, thereby reducing the transfer of heat to the inner layer of the fabric or the wearer’s skin, and increasing the comfort of fireproof fabrics.
Therefore, tungsten filament-reinforced fireproof fabrics are widely used in firefighter uniforms, industrial protective clothing, and work clothes in high-temperature working environments to protect personnel from high temperatures and flames.
- Light sources in fire lighting equipment
Although LED light sources are becoming more and more popular in firefighting equipment, tungsten filament bulbs still have certain application advantages:
Low cost: Tungsten filament bulbs are relatively cheap, so they can be used in large quantities in firefighting equipment to improve the scalability of lamps.
High heat generation: Tungsten filament bulbs generate relatively high heat when working. Although explosion-proof requirements need to be considered to avoid danger, this heat generation may help provide additional lighting and heat in certain specific occasions.
However, it should be noted that the life of tungsten filament bulbs is relatively short, usually about 1,000 hours under common lighting conditions. Therefore, in fire-fighting equipment that requires long-term lighting, bulbs may need to be replaced more frequently.
- Applications in other fire-fighting equipment
In addition to the above applications, tungsten filaments may also be used in other fire-fighting equipment, such as high-temperature sensors, thermocouples, etc. These devices need to work stably in high-temperature environments, and the high melting point and stability of tungsten filaments make them an ideal material choice.
In summary, the application of tungsten filaments in fire-fighting equipment is multifaceted, including as a reinforcement material for fire-resistant fabrics, a light source in fire-fighting lighting equipment, and other equipment that requires high-temperature stability. These applications make full use of the characteristics of tungsten filaments such as high melting point, high strength and stability.
