The carbon pre - oxidized fiber staple yarn woven fabric is a remarkable high - performance woven material. It is crafted from polyacrylonitrile (PAN) based fibers that have been subjected to pre - oxidation treatment. This treatment endows the fabric with outstanding properties, including excellent high - temperature resistance, remarkable flame retardancy, and high strength.
Feature:
Exceptional High - Temperature Resistance:
This fabric can endure high - temperature environments over extended periods. It has a stable working temperature above 200°C and can tolerate short - term temperatures up to 800°C. This makes it suitable for applications where high - heat exposure is a concern.
Outstanding Flame Retardancy:
The material is self - extinguishing, meaning it doesn’t catch fire easily. Moreover, when it does encounter flames, it does not drip, which is a crucial safety feature, especially in applications where fire hazards are present.
Chemical Stability:
It shows good resistance to acids, alkalis, and organic solvents. This chemical stability makes it highly resistant to corrosion, ensuring a long service life in various chemical environments.
Dimensional Stability:
With low thermal shrinkage, the fabric maintains excellent dimensional stability. This characteristic is essential for applications where precise dimensions are required, as it ensures that the fabric retains its shape even under varying temperature conditions.
Applications:
Welding Protection (Welding Blankets)
Function in Welding: Ideal for welding blankets due to high - temperature resistance. Protects equipment, workbenches, and personnel from heat, sparks, and molten splashes during welding.
Fire - Resistant Mechanism: Self - extinguishing and non - dripping. Sparks won't cause ignition or spread, and non - dripping avoids igniting nearby flammables.
General Fire - Resistance Applications
Industrial Fire Barriers: Used in industrial areas like near furnaces or chemical storage to slow or prevent fire spread, e.g., chemical plant fire - resistant curtains.
Building Fire - Protection Linings: Serves as lining for fire - rated doors, walls, and ceilings in construction, enhancing fire - protection, e.g., high - rise building partitions.
Fire - Resistant Covers for Equipment: Makes covers for electrical equipment, reducing fire risk and protecting from external fires, e.g., generator covers in power stations..
