Tempered fire-resistant glass, as the name suggests, refers to glass that has been tempered and has fire-resistant properties, and is a special type of glass product. Tempering treatment is the process of increasing the strength of glass through physical or chemical methods, making it less likely to break under external impact. Even if broken, it will form smaller particles, reducing harm to the human body. Fire resistance performance refers to the ability of glass to maintain a certain structure and function in high-temperature environments and is not easy to soften or crack.
Introduction to Classification of Tempered Fire-resistant Glass
|
Classified by fire resistance level |
Class A fire-resistant glass |
It has high fire resistance and can withstand high temperatures for a certain period of time and temperature. It is usually used for fireproof partitions, fireproof windows, etc. |
|
Class B fire-resistant glass |
The fire resistance performance is relatively low, but it can still withstand high temperatures for a certain period of time, suitable for some places with less strict requirements for fire resistance. |
|
|
Classified by tempering method |
Physically tempered fire-resistant glass |
By using physical methods such as rapid cooling, compressive stress is formed on the surface of the glass to increase its strength. This tempering method does not change the chemical composition of the glass, so it will not affect its fire resistance performance. |
|
Chemical tempered fire-resistant glass |
By changing the chemical composition of the glass surface, a layer of compressive stress is formed, thereby improving the strength of the glass. This tempering method may have a certain impact on the fire resistance performance of glass. |

Tempered fire-resistant glass for building use |
Mainly used in fire partitions, fire windows, curtain walls, and other parts of buildings, it has good fire resistance and explosion-proof performance. |
|
Industrial tempered fire-resistant glass |
Used for observation windows and operation windows in industrial equipment, high-temperature furnaces, and other places, capable of withstanding high temperatures and certain mechanical impacts. |
