The heat resistance time of tempered glass mainly depends on its thickness and temperature change range.

Tempered glass is a type of prestressed glass that creates compressive stress on the glass surface through chemical or physical methods, thereby improving the strength and safety of the glass. the surface of tempered glass has compressive stress, while tensile stress is formed inside. this structure allows the glass to better offset stress when it is subjected to external forces, thereby enhancing its resistance to wind pressure, cold and heat and impact.
Heat Resistance of Tempered Glass:
The fire resistance time of ordinary tempered glass is generally about 10 to 30 minutes. The specific time will vary depending on factors such as production process, control method, glass thickness and shape. For example, tempered glass with a thickness of 5 mm can withstand high temperatures of 240 degrees, while tempered glass with a thickness of 10 mm can withstand high temperatures of 280 degrees. In addition, tempered glass may undergo thermal bending at high temperatures, causing overall damage, so its fire resistance time will also be affected.
To improve the heat resistance of tempered glass, consider using reinforced glass such as laminated glass and tempered soda-lime glass. Laminated glass is made of a transparent polyvinyl butyral film sandwiched between two or more layers of glass. It has high fire resistance and can reduce damage from fragments. Tempered soda-lime glass has improved fire resistance and mechanical strength through special chemical composition and processing technology.
When choosing tempered glass, the appropriate glass material should be selected according to the building's usage environment and requirements. If higher fire resistance is required in the building, priority can be given to using reinforced glass materials such as laminated glass or tempered soda-lime glass. At the same time, you should also pay attention to factors such as the thickness, shape, and size of the glass to ensure that you purchase high-quality glass products that meet your actual needs
How to improve the heat resistance of tempered glass
The following methods can be used to improve the heat resistance of tempered glass:
1. Choose a high-temperature-resistant glass substrate:
Ordinary glass is easy to soften at high temperatures, so you can choose a high-temperature-resistant glass substrate, such as quartz glass or borosilicate glass. These materials have high heat resistance.
2. Use high-temperature-resistant coating:
Coating a layer of high-temperature-resistant and anti-aging coating on the glass surface can protect the internal materials from high temperature and ultraviolet rays, thereby improving heat resistance and extending service life.
3.Optimized design:
By optimizing the structural design and reducing stress concentration, the heat resistance of the glass can be improved. For example, use rounded corners instead of sharp corners, increase the size of joints, etc.
4. Heat treatment:
Heat treatment of glass can improve its internal structure and improve its heat resistance and fatigue resistance. The temperature and time need to be strictly controlled during the heat treatment process to ensure that the glass achieves ideal heat resistance
5.Controlling the heating process of the tempering furnace:
During the heating process of the tempering furnace, it is necessary to accurately control the temperature and heating rate to avoid local overheating and stress concentration. Evenly heats up to avoid glass breakage or deformation
6.Use high-temperature-resistant curing agents and accelerators:
Adding high-temperature-resistant curing agents and accelerators to the resin formula can increase the cross-linking density of the resin, thereby improving heat resistance.
