Pre-oxidized aluminum-coated fabric is a high-performance composite material with excellent high temperature resistance, chemical corrosion resistance, and fire retardant properties. Combining the excellent properties of pre-oxidized fiber and the protective properties of aluminum foil, it is widely used in various high temperature and protective fields. Its main components are pre-oxidized fiber and aluminum coating.
The following is a detailed introduction to these two parts:
Pre-oxidized fiber is made of polyacrylonitrile as raw material and is obtained by high-temperature thermal stabilization treatment. It has high flame retardancy, a limiting oxygen index greater than 40%, and excellent thermal stability. During combustion, the fiber does not melt, soften, shrink, or drop, and is a quasi-non-combustible product. Pre-oxidized fiber is a fiber treated by a special process.
Its manufacturing process includes the following steps: Raw material selection: Polyacrylonitrile (PAN) fiber is usually selected as the raw material. Pre-oxidation treatment: PAN fiber is heated to 200-300 degrees Celsius in air to change its molecular structure, thereby forming a stable pre-oxidized fiber. This process not only enhances the thermal stability of the fiber, but also makes it have certain conductivity and antistatic properties.
High temperature resistance: pre-oxidized yarn can withstand high temperatures of more than 300 degrees Celsius without obvious physical changes. Fire retardant: Its inherent fire resistance makes it difficult to burn when it encounters fire, and no molten droplets will be produced, reducing the risk of fire. Chemical corrosion resistance: It has strong resistance to chemicals such as acids and alkalis. High strength: Although not as good as carbon fiber, it still has high mechanical strength and toughness.
Aluminum coating
Coating a layer of aluminum on the surface of pre-oxidized yarn fabric can further improve its performance. The functions of aluminum coating include:
Reflecting thermal radiation: Aluminum has good reflective properties and can effectively reflect infrared and other thermal radiation, reducing the surface temperature of the material.
Waterproof and oil-proof: Aluminum coating can provide excellent waterproof and oil-proof properties, allowing the material to maintain its performance in a humid or oily environment.
Ultraviolet resistance: Aluminum coating can block ultraviolet rays and extend the service life of the material.
Improving wear resistance: Aluminum coating can increase the surface hardness of the material, reduce wear and extend the service life.
Pre-oxidized aluminum-coated fabrics properties
The following are the main properties of pre-oxidized aluminum-coated fabrics:
- High temperature resistance Pre-oxidized wire itself has excellent high temperature resistance and can withstand temperatures over 300 degrees Celsius. The aluminum coating further improves the heat resistance, can reflect heat radiation, and reduce the temperature of the material surface.
- Fire retardant performance Pre-oxidized wire material has inherent flame retardancy, is not easy to burn when exposed to fire, and does not produce molten droplets, reducing secondary damage in fire. The presence of aluminum coating further enhances this property, making it perform better in high temperatures and flames.
- Chemical corrosion resistance Pre-oxidized wire has good tolerance to a variety of chemicals (including acids and alkalis), and is suitable for use in chemically corrosive environments. Aluminum coating further improves resistance to chemical corrosion, especially in humid or oily environments.
- Lightweight and wear resistance The combination of pre-oxidized wire and aluminum coating makes the material have a low weight while maintaining high strength and durability, suitable for applications with strict weight requirements. Aluminum coating increases the surface hardness of the material and enhances its wear resistance, making it suitable for environments with frequent friction or wear.
- Conductivity and antistatic properties During the pre-oxidation process, the pre-oxidized wire has certain conductivity and antistatic properties, making it suitable for environments that require antistatic, such as the electronics industry.
- Waterproof and oil-proof properties The aluminum coating provides good waterproof and oil-proof properties, allowing the material to maintain its performance in a humid or oily environment and extend its service life.
- Insulation and reflection properties The combination of pre-oxidized wire and aluminum coating provides good insulation properties, making it suitable for occasions that require thermal insulation, such as industrial insulation materials, building insulation materials, etc. The reflective properties of the aluminum coating can effectively reflect thermal radiation and light radiation, reduce the temperature of the material surface, and is suitable for protective materials in high temperature environments.
- Anti-convection heat energy reaches B2 level, anti-convection heat B2 level, anti-radiation heat 3 level, anti-aluminum liquid splash D3 level, anti-iron liquid splash E3 level, anti-contact heat F2 level, meeting the EN11612 standard.
