防火玻璃也被称为安全玻璃，具有更强的力学强度以及抗冲击能力，当然了，比较主要的还是有着强大的防火性能，因此，被广泛使用在高层建筑、幕墙，能够应对火灾的紧急情况。

Fireproof glass, also known as safety glass, has stronger mechanical strength and impact resistance. Of course, the most important is a strong fireproof performance. Therefore, it is widely used in high-rise buildings and curtain walls to cope with the emergency of fire.

防火玻璃现如今正在逐步被广泛使用于大型公共建筑隔断、防火分区、室外幕墙等建筑部位，防火玻璃以透明为特性，比较大限度地满足了建筑防火和建筑美学的和谐统一。

Fireproof glass is now being widely used in large public building partition, fireproof partition, outdoor curtain wall and other building parts. The fireproof glass is characterized by transparency, which maximizes the harmony of building fire prevention and architectural aesthetics.

防火玻璃

Fireproof glass

按照耐火性能等级可以把防火玻璃分为三大类：

According to fire resistance rating, fireproof glass can be divided into three categories.

A类：同时满足耐火完整性、耐火隔热性要求的防火玻璃。

Class A: fireproof glass that meets the requirements of fire integrity and fire insulation.

B类：同时满足耐火完整性、热辐射强度要求的防火玻璃。

Class B: fireproof glass that meets the requirements of fire integrity and heat radiation intensity.

C类：仅满足耐火完整性要求的防火玻璃。

Class C: fireproof glass that only meets the requirements of fire integrity.

再和大家说说耐火性能的指标。耐火完整性：指能在一定时间内防止火焰穿透或防止火焰在背火面出现的能力。耐火隔热性：指在一定时间内其背火面温度不超过规定值的能力。热辐射强度：指在玻璃背火面一定距离、一定时间内不超过热辐射强度的能力。

And then talk to you about the index of fire resistance. Fire integrity: the ability to prevent flames from penetrating or preventing flames from appearing on the back fire surface within a certain time. Fire resistance and heat insulation: the ability of the back fire surface temperature does not exceed the specified value within a certain time. Thermal radiation intensity: the ability to not exceed the heat radiation intensity at a certain distance and within a certain time.
