Fire-resistant glass, which comprises at least two pieces of glass, between which is placed a transparent refractory material consisting of a cured hydrated alkali metal polysilicate. There is at least one piece of glass that has a primer layer on its surface in contact with the refractory material, and its adhesion to the refractory layer is reduced at the temperature of the fire resistance test. At the temperature of the fire resistance test, the glass sheet exposed to fire can be completely separated from the refractory material. Therefore, the polysilicate refractory baffle is still intact, even when the glass sheet exposed to the fire bursts and fragments fall.
Application of Fire-proof Glass in Fire Safety
In the past two years, there have been several major fire accidents such as the North Annex Building of CCTV New Site and high-rise residential buildings in Jing'an District of Shanghai, causing serious losses and damages. The state has conducted a wide range of fire safety inspections, and the people’s awareness of fire prevention has gradually increased. Fire-retardant glass has the advantages of retarding the spread of fire, heat insulation, smoke separation, etc. It can create favorable conditions for the rescue of people, property, and buildings in the event of a fire, minimize losses, and is favored by the people, and the market potential of fire-resistant glass. huge. (Classification of China's fire-resistant glass market in 2014) Fire-resistant glass is a new type of building fire protection material. It is mainly used to make fire doors, firewalls, fire partitions, etc. Europe divides fire-proof glass from fire-resistance grades. Fire-resistant glass can be divided into 30 minutes. , 60 minutes and 90 minutes three levels. The monolithic fire-retardant glass is a fire-resistant glass constructed of single-layer glass and is mainly used for building partitions of large-scale public buildings, fire partitions, and outdoor curtain walls. After a long time of high-temperature ion exchange chemical treatment process, the single-piece fireproof glass has the advantage of low thermal expansion rate, can maintain the glass softening without breaking at high temperature for a period of time, and prevent the open flame and poisonousness of the welcome surface by maintaining the integrity of the glass. Harmful gas, but not insulated by heat. In addition, in addition to fireproof glass, the importance of glass frames should also be emphasized. If the frame is not fireproof, it will be easy to soften and deform in the event of a fire, and even the best fireproof glass will not function properly. Therefore, it is also important to equip with a fireproof frame attachment. After 2014, China will fully launch the new standards for fire protection certification for public buildings and civil buildings, and there will be blowout requirements for the application area of single-piece fire-resistant glass.
