Now, let’s explore the main factors that cause aging in fiber-reinforced silicate fireproof boards:

1. Thermal Stress
   Temperature fluctuations cause thermal expansion and contraction, leading to volume changes in the non-structural components of fiber-reinforced silicate fireproof boards. This keeps the material in an unstable state, making thermal stress one of the primary causes of deterioration in high-rise building applications.

2. Wind Pressure
   Wind exerts both positive pressure (pushing force) and negative pressure (suction force) on building exteriors. These forces can significantly damage the external insulation layer, particularly in tall structures.

3. Seismic Forces
   Earthquakes generate forces that cause building structures and fireproof boards to compress, shear, or deform. The greater the seismic force, the more severe the potential damage to the boards.

4. Fire Exposure
   Fiber-reinforced silicate fireproof boards in high-rise buildings must possess strong fire resistance. In a fire, they should prevent the spread of flames, avoid releasing dust or toxic gases, and maintain structural integrity without significant loss of strength, volume, or surface defects such as cracking or collapse. Failure to do so may endanger residents or firefighters and complicate rescue operations.
