Common Anti-Explosion Materials Used in Glass Curtain Walls
1 Tempered Glass: Tempered glass, due to its high hardness and strength, is widely used in high-rise buildings. It is produced by heating float glass to a certain temperature and then rapidly cooling it. The quick temperature change causes the outer layer to cool and solidify rapidly while the inner layer cools slowly, creating surface compression that enhances the glass’s strength. Generally, its mechanical strength is three to five times higher than ordinary glass, and the internal tensile stress increases its heat resistance and stability. Tempered glass can withstand a certain range of impacts and temperature variations. When subjected to significant impact, it breaks into small, honeycomb-shaped particles rather than shattering into sharp pieces. Therefore, tempered glass not only offers high strength and thermal stability but also boasts excellent safety performance.
2 High-Strength Monolithic Fireproof Glass: By heating float glass to high temperatures and treating it with special chemicals, the surface sodium is replaced over several hours, forming monolithic fireproof glass. As a fireproof glass, it naturally provides excellent fire resistance, maintaining its integrity in flames up to 1000°C for extended periods. With the same thickness, high-strength monolithic fireproof glass is six to twelve times stronger than float glass. In case of an explosion, it can extend the evacuation time for people and provide more time for rescue operations.
3 Bomb-Resistant Glass: Bomb-resistant glass is one of the safest functional glasses produced in China. It effectively withstands the shock waves from explosions, the thermal shock waves from high-temperature flames, and bullet impacts. The anti-explosion protection of glass curtain walls mainly addresses the sudden expansive shock waves and massive vibrations caused by explosions. To resist the enormous power of bomb attacks, the glass must endure various shock waves and fragment impacts.
4 Safety Explosion-Proof Film: Safety explosion-proof films can prevent glass fragments from scattering and deter thieves from breaking glass to access important areas, protecting artworks from damage. Considering the bulletproof, anti-theft, and explosion-proof safety performance of glass, selecting better surface materials can fundamentally address these issues in the design.
5 Curtain Wall Keel: The curtain wall keel typically uses high-strength steel to withstand the peak pressure generated during explosions, and its surface is treated with fireproof materials. This allows it to resist various high-intensity explosion pressures.
