2019-12-16 1579

With the development of the city, there are more and more people living together, and the problems gradually appear. In urban planning and the design of various large-scale buildings, fire-proof glass has become the most popular glass, so fire-proof glass is used more and more widely. The following Xiaobian introduces us to fireproof glass.

Advantages of fireproof glass:

1. Sound insulation.

Fireproof glass has the sound insulation function of general glass. When installed in large public places, it can isolate noise, such as libraries, museums, exhibition halls, large shopping malls, etc.

2. High strength.

Fireproof glass not only has fire resistance, but also has high hardness. Under the same glass thickness, the strength of single fireproof glass is 6-12 times that of float glass; It is 2-3 times that of tempered glass.

3. Superior fire resistance

防火玻璃

The non insulated glass (door) can remain unbroken for more than 90 minutes under the impact of flame up to 700 ℃, and then won a valuable moment for people's escape and disaster relief operations.

4. Safety performance

After the non heat insulating fireproof glass (door) is broken, the fragments are in an obtuse angle state, and the fragments are smaller than the fragments of tempered glass, so even if it is damaged, it will not cause harm to human body.

5. High weatherability

Compared with the traditional grouting or composite sandwich fire-proof glass, the non thermal insulation fire-proof glass is characterized by high weather resistance in addition to high strength. It has no changes affecting the appearance and service performance under the long-time irradiation of ultraviolet rays, and can maintain transparency and brightness for a long time.
