Whether Fire-Proof Glass Must Be Tempered


Fire Glass is laminated glass, fire glass does not have to be tempered. Fire-proof glass can meet the requirements of Fire Protection. The physical properties of fire-proof glass are special, and it will soften under high temperature rather than break immediately. The fire resistance time of ordinary fire-proof glass at 1000℃ is 90-120 minutes. Tempered glass is just a kind of safety glass. Under the action of high temperature and external force. After the tempered glass is broken, it remains and becomes round fragments. The right answer is that toughened glass cannot be used instead of fireproof glass. The two are glass with completely different physical properties.

Difference between fireproof glass and toughened glass toughened glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface, when the glass bears external force, it first offsets the surface stress, thus improving the bearing capacity and enhancing the wind pressure resistance, cold and summer heat resistance, impact resistance, etc. There are two main advantages of tempered glass: first, the strength is several times higher than that of ordinary glass; Second, it is safe to use, and its bearing capacity increases to improve the fragile property, even if the tempered glass is damaged, there are small fragments without acute angle, which greatly reduces the damage to human body. The function of fire-proof glass in fire prevention is mainly to control the spread of fire or smoke isolation, which is a measure-type fireproof material. Its fire-proof effect is evaluated by fire-proof performance. Classification of fire-proof glass: fire-proof glass is A kind of special glass that can maintain its integrity and heat insulation in the specified flame resistance test. It can be divided into three categories according to the fire-resistant performance grade: Class A meets the fire-resistant integrity at the same time, fire-resistant and heat-insulating glass. Including composite fireproof glass and pouring fireproof glass. This kind of glass has the properties of light transmission, fire prevention (smoke isolation, fire-resist, shielding thermal radiation), sound insulation and impact resistance, and is suitable for building decoration steel and wood fire doors, windows, brightening, partition wall and lighting roofs.
