        What are the excellent functions of single fireproof glass

        2020-02-17 2102

        The excellent functions of high-strength monolithic fireproof glass are embodied in the following aspects:

        -- high fire prevention function: high strength monolithic fireproof glass is a kind of curtain wall or door and window glass for building exterior wall with fire prevention function. It can not burst for 96 ~ 183 minutes under the impact of 1000 ℃ flame, and then effectively curb the extension of flame and smoke, which is conducive to finding the fire in time and giving people a satisfactory time to evacuate the site.

        -- high strength function: under the condition of the same thickness, its strength is 6 ~ 12 times that of ordinary float glass and 1.5 ~ 3 times that of tempered glass. Therefore, under the same wind pressure, it can choose thinner thickness or larger area planning, so as to add a sense of permeability and reduce the cost. Generally, the toughened glass is damaged when the load is 900kg, but its deflection is 326mm without damage when the load reaches 5500kg. The strength of high-strength monolithic fireproof glass is 4 ~ 6 times that of flat glass with the same thickness and 1.5 ~ 2 times that of tempered glass with the same thickness. Moreover, if it is damaged, the high-strength monolithic fireproof glass is in small particle shape and obtuse angle shape, so as to ensure that it will not cause great damage to human body in case of earthquake, fire or damage force.

        -- high weather resistance: compared with traditional grouted or laminated fire-proof glass, high-strength monolithic fire-proof glass also has high weather resistance in addition to high strength. Chemical grouting or laminated glass will soon turn milky white and bubble under ultraviolet irradiation, losing the basic function of glass permeability, which is also the main reason why fireproof glass can not be used as exterior wall. The high-strength monolithic fireproof glass is the same as ordinary glass, and will not change under ultraviolet irradiation.

        -- machinability: high strength monolithic fireproof glass has good machinability. It can be processed into laminated glass, insulating glass, coated glass and point curtain wall glass. It can also be used as an indoor fire compartment and escape passage, making a great breakthrough in the application area of a single piece. It can reach a height of 3M and a width of 2m, and the equipment is also simple.
