The application advantages of ceramic fiberboard in fire doors are mainly reflected in the following aspects:
1. Excellent fire performance, mainly manifested in the following two aspects:
1. High refractory temperature: Ceramic fiberboard can remain stable at extremely high temperatures, and is usually able to work stably for a long time in a high temperature environment from 1000 °C to 1400 °C without obvious physical or chemical changes. This property makes it an ideal choice for the filling of fire doors to prevent the spread of fire.
2. Non-combustible: Ceramic fiberboard is a non-combustible material, which will not produce toxic gases or smoke even in a fire, providing valuable time for escape and rescue.
2. Good thermal insulation performance: ceramic fiber board has a very low thermal conductivity, which can effectively prevent heat conduction and provide superior thermal insulation effect. When used in fire doors, it can significantly reduce the temperature difference between the two sides of the door body during a fire and protect the area behind the door from high temperatures.
3. Light weight and high strength, the characteristics are mainly manifested in the following two aspects:
1. Light weight: Compared with traditional refractory bricks and other materials, ceramic fiberboard is lighter in weight and easy to handle and install. This not only reduces the overall weight of the fire door, reduces the burden on the door frame and hinges, but also improves the efficiency of installation.
2. High compressive strength: Despite its light weight, ceramic fiberboard still has high compressive strength, which can withstand a certain external impact and ensure the structural stability and safety of fire doors.
Fourth, the construction is convenient, mainly manifested as:
1. Easy processability: ceramic fiberboard has good machinability and can be cut into various shapes and sizes according to different needs. This makes it more flexible and convenient in the production process of fire doors, which can be customized according to the specific size and shape of the door body.
2. Short construction period: due to the simple and fast construction of ceramic fiberboard, the production and installation period of fire doors can be significantly shortened and the construction cost can be reduced.
5. Durability and environmental protection
Chemical Resistance: Ceramic fiberboard has good corrosion resistance to most chemicals and can be used for a long time without damage in harsh chemical environments.
Environmental protection and pollution-free: ceramic fiberboard does not produce harmful substances in the production and use process, and meets the requirements of environmental protection.
To sum up, the application advantages of ceramic fiberboard in fireproof doors are mainly reflected in its excellent fire performance, good thermal insulation performance, light weight and high strength, convenient construction, durability and environmental protection. These advantages make ceramic fiberboard one of the preferred filling materials for fire doors.
