As a special building material, composite fireproof glass plays an important role in the field of fire safety. Whether it can withstand long-term burning of high-temperature open flames has attracted much attention.
Composite fireproof glass is mainly composed of two or more layers of glass with a fireproof adhesive layer in the middle. When encountering high-temperature open flames, the fireproof adhesive layer will rapidly expand and carbonize. This reaction can not only prevent the rapid transfer of heat, but also block the penetration of flames to a certain extent.
According to experimental data, in standard fire resistance tests, composite fireproof glass of certain specifications can maintain integrity and thermal insulation for 1 to 3 hours under high-temperature open flames of 900-1000℃. This means that during this period, the glass will not break, and the temperature rise of the back-fire surface is effectively controlled, which can prevent the fire from spreading to adjacent areas.
In actual applications, many building fire cases have also verified the fireproof performance of composite fireproof glass. For example, in some commercial buildings where fires occurred, the fire was effectively confined to the area near the fire point where composite fireproof glass was installed, and it did not spread to other spaces through the glass, which bought precious time for personnel evacuation and fire rescue.
However, the ability of composite fireproof glass to resist high-temperature open flames is not unlimited. If the burning time is too long and exceeds its fire resistance limit, the protective effect of the fireproof adhesive layer will gradually weaken, and the glass may eventually break. Moreover, the specific fire resistance of glass is also affected by many factors such as its thickness, the material of the fireproof adhesive layer, and the installation method.
Composite fireproof glass can effectively resist the burning of high-temperature open flames within the specified fire resistance time, providing reliable protection for building fire safety. However, when using it, it is necessary to reasonably select and install composite fireproof glass according to the fire protection requirements of the building to give full play to its fire protection performance.
