The reason of using toughened glass in revolving door

The revolving door only embodies the unique elegant design appearance, but also uses superior materials, such as the door glass of the revolving door. Ordinary glass can't be used as the type material of revolving door, because ordinary glass can't meet the safety stability performance of the profile required by revolving door. However, toughened glass meets this requirement, so many of the glass used on revolving doors are toughened glass.

Why is toughened glass safe?

Toughened glass is one of the safety glass categories, which can also be called prestressed glass. In order to improve the strength of the glass, chemical physical methods are usually used to form compressive stress on the surface of the glass. When the glass bears external force, the surface stress is first offset, then the bearing capacity of the glass to the outside is improved, the resistance to wind pressure, heat cold, impact, etc. of the glass is enhanced. The increase of the bearing capacity of toughened glass leads to the increase of its safety. On the other hand, the safety of toughened glass is mainly reflected in the use. Even if the toughened glass is damaged, it will be a small fragment without sharp angle, the damage to human body will be sharply reduced. The properties of toughened glass are 3-5 times higher than that of ordinary glass. It can bear the temperature difference of more than 250 degrees, which has obvious effect on preventing thermal explosion. This provides a guarantee for the safety of qualified materials for high-rise buildings.

Why is toughened glass stable?

The stability referred to here is mainly thermal stability. The thermal stability of toughened glass is very good. The temperature difference it can bear is three times that of ordinary glass, it can bear 300 ℃ temperature difference. So it will be as fragile as ordinary glass, because of the dramatic increase decrease of temperature, it will change greatly. To some extent, it is also the embodiment of security, that is, the stability performance helps to improve the security performance.
