As a fireproof glass partition, according to the building fire spread of the way, it should have the following basic characteristics: (1) Smoke: In the event of a fire, can block the fire from the smoke from the side of the fire to the back of the fire side. This is the most basic requirements, a reasonable and effective way to prevent the smoke generated by fire, to avoid the formation of chimney effect, is to control the spread of fire, to ensure that the evacuation channels unblocked or effective refuge. (2) Fire-resistance integrity: When the fire occurs, the side of the fire, can be in a certain period of time to prevent the flames from penetrating or preventing flames in the back of the fire surface. According to the design requirements of building fire prevention, fire partition should have good integrality. If a burning is poured down, the fire will collapse or not reach the requirements of the fire time limit, fires can also spread, not to reduce the loss of fire purposes. (3) Fire-resistant heat insulation: In the fire occurs, the side of the fire, can be in a certain period of time its back surface temperature rise does not ignite back fire area items. If satisfied with the smoke, to ensure the integrity, but because the heat generated by fire through the fire glass after a large number of thermal radiation caused by the fire surface of the flammable burning, also did not play a role in fire.
