Aluminum silicate fiber board has excellent fire resistance, mainly reflected in the following aspects:

I. High temperature resistance

Aluminum silicate fiber board can work stably at high temperature for a long time. According to different production processes and raw materials, its temperature range is usually from 1000℃ to 1350℃. For example, the use temperature of zirconium-containing aluminum silicate fiber board can reach 1350℃, while the use temperature of ordinary is generally around 1100℃.

II. Fire performance

The main component of aluminum silicate fiber board is inorganic aluminum silicate fiber, which is incombustible and will not burn or release toxic gases even at high temperature. Its fireproof performance usually reaches the standard of Class A incombustible material, which can effectively prevent the spread and spread of flame.

III. Thermal insulation performance

The thermal conductivity of aluminum silicate fiber board is low, usually around 0.085 W/m·K, which makes it effective in heat insulation and reduces heat transfer in high temperature environment.

IV. Fire resistance limit

In practical application, the fire resistance limit of aluminum silicate fiber board is outstanding. For example, a aluminum silicate fiber board with a thickness of 40mm can meet the fire resistance limit requirement of 1 hour. The fire resistance limit of some composite fireproof aluminum silicate fiber blankets can even reach 180 minutes.

V. Chemical stability

Aluminum silicate fiber board has good chemical stability at high temperature, is not easy to be corroded, and can adapt to complex chemical environment.

VI. Application examples

Building fire protection: aluminum silicate fiber board is often used in firewall, fire door, fire partition and other parts, which can effectively improve the fire protection performance of buildings.

Industrial high-temperature equipment: In the thermal insulation of industrial furnaces, high-temperature pipelines and other equipment, aluminum silicate fiber board can significantly reduce the heat loss and protect the equipment from high temperature damage.

To sum up, aluminum silicate fiber board has become an ideal fire-proof and heat-insulating material in the fields of architecture and industry because of its excellent high temperature resistance, fire prevention, heat insulation and chemical stability.
