We all know that there are many kinds of glass, such as household glass, fire-proof glass, tempered glass and bulletproof glass. How much do you know about all kinds of functional glass? What are the differences between composite fire-proof glass and tempered glass? Let's introduce it to you by Xiaobian

Toughened glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are generally used to form compressive stress on the surface of glass. When the glass bears external force, it first offsets the surface stress, and then improves the bearing ability to enhance the wind pressure resistance, summer and cold resistance, impact and so on. There are two primary benefits of tempered glass:

The first is that the strength is several times higher than that of ordinary glass

Second, it is safe to use, its bearing capacity is increased, and the fragile property is improved. Even if the tempered glass is damaged, it is a small fragment without acute angle, which greatly reduces the damage to the human body.

The main function of composite fire-proof glass in fire prevention is to control the extension of fire or smoke separation. It is a method type fire-proof data. Its fire-proof function is evaluated by fire-resistant function. Classification of fireproof glass

Composite fireproof glass is a kind of special glass that can adhere to its integrity and thermal insulation in regular fire resistance test. It is divided into three categories according to fire resistance function grade:

Class a fireproof glass that meets the requirements of fire integrity, fire resistance and heat insulation. It includes composite fire-proof glass and cast-in-place fire-proof glass. This kind of glass has the functions of light transmission, fire prevention (smoke, fire and heat radiation), sound insulation and impact resistance. It is suitable for the construction and decoration of steel wood fire doors, windows, upper lighting, partition walls, daylighting roofs, smoke retaining vertical walls, perspective floors and other building components that need to be transparent and fire-proof.

Class B marine fireproof glass, including sidescuttle fireproof glass and rectangular window fireproof glass. The outer surface glass plate is tempered safety glass, and the data type of inner and outer surface glass plate can be selected arbitrarily.

Class C single piece fireproof glass only satisfying the fire integrity requirements. This kind of glass has the characteristics of light transmission, fire prevention, smoke separation and high strength. It is applicable to fireproof glass partition walls, fireproof windows, outdoor curtain walls, etc. without thermal insulation requirements.
