Features:
- Lightweight and High Strength: Fireproof Composite is typically composed of reinforced carbon fiber or glass fiber in an organic resin matrix, providing a lightweight and high-strength structure.
- Fireproof performance: Fireproof Composite can meet specific fire protection requirements, such as fire standards for wall, ceiling, and floor covering materials.
- Low heat release rate: The low heat release rate of Fireproof Composite means that less heat is released during combustion, reducing the risk of fire.
- Thermal insulation: Fireproof Composite such as SiO2 gas gel has high specific surface area, high porosity and low thermal conductivity, which makes it perform well in thermal insulation.
- Environmental stability: Fireproof Composite has good stability under high temperature conditions, is not easily decomposed, and is suitable for applications that require fire protection.
- Multifunctionality: Fireproof Composite not only provides fire protection, but may also have other functions such as sound absorption, increasing the diversity of its applications.
- Environmental friendliness: With increasing attention to environmental impact, the development of Fireproof Composite places greater emphasis on using eco-friendly materials to reduce the release of toxic gases and chemicals.
Application:
- Aerospace field: Fireproof Composite is used in the aerospace industry to produce lightweight structures while maintaining stability under extreme high temperatures, reducing the risk of decomposition and collapse in the event of a fire.
- Railway and maritime industry: In the railway and maritime industry, Fireproof Composite is used to improve the structural fire resistance of vehicles and ships, ensuring passenger safety.
- Construction industry: Fireproof Composite is used for building insulation layers. Compared with traditional insulation materials, it has lower heat loss and stronger durability, making it suitable for civil building insulation.
- Passive fire protection system: In passive fire protection systems such as urban underground spaces, super insulating fireproof materials play an important role due to their ultra-low thermal conductivity and nano porous structure.
