Fire-proof glass partition is widely used in more and more buildings. Fire-proof glass partition is widely used in closed shelter floor,closed evacuation staircase and fire-proof partition of large-scale venues. 

Fire-proof glass partition, as a building component with certain fire resistance limit, is widely recognized for controlling and preventing fire from spreading vertically or horizontally to other parts of the same building. 

However, as a special fire protection product, if its design and material selection are improper, it may not form a real fire protection zone and can not achieve the purpose of reducing the loss caused by fire.


Fireproof property of fire-proof glass partition

Fire-proof glass partition belongs to passive fire-proof system, its main function is to prevent the spread of fire.

 There are four ways of building fire spread, including flame spread, heat conduction, heat convection and radiation, accompanied by the spread of smoke. 

In addition to the first way that the flame spreads the fire by directly igniting the combustible material, the last three ways are to make the combustible material be ignited by different heat transfer processes, thus causing the spread of the fire. 

Therefore, the key point of fire protection partition design is how to prevent the spread of fire.

According to the relevant specifications, the fire-resistant grade of buildings is required to ensure that buildings do not collapse in a short period of time in a fire. Fire-proof glass partition is a part of the building, its role is to ensure that the fire in a certain period of time after the occurrence of intact, that is, fire resistance. 

Therefore, the selection of fire-resistant grade in design should be determined according to the fire-resistant grade of the building in which it is located and the fire-resistant requirement of the part of the building in which it is located. 

Functional requirements of fire-proof glass partition

According to the way of building fire spread and the function of fire-proof glass partition, it should have the following basic characteristics:

1. Cut off smoke. That is, when a fire occurs, the smoke generated by the fire can be blocked from the burning side to the backfire side. This is the most basic requirement. 

Reasonable and effective blocking is the smoke generated by fire, avoiding chimney effect, controlling the spread of fire, ensuring the smooth passage of evacuation or effective refuge.

2. Fire-resistant integrity. That is to say, when a fire occurs on one side, it can prevent the flame from penetrating or appearing on the back of the fire for a certain period of time. 

According to the design requirements of building fire protection, fire protection partition should have good integrity. If a fire falls down, it collapses or fails to meet the requirements of the time limit for fire prevention, the fire will spread and the purpose of reducing fire losses will not be achieved. 

3. Fire resistance and heat insulation. That is to say, when a fire occurs on one side, the temperature on the back of the fire can rise within a certain period of time so as not to ignite the articles in the back fire area. 

If the smoke insulation is satisfied, the integrity is guaranteed, but because the heat generated by the fire passes through a large number of thermal radiation behind the fire-proof glass, the flammable material on the back of the fire burns, and it does not play a role in fire prevention.
