        What are the influencing factors of fireproof glass window on fire

        2020-02-13 2307

        The fire on the outer wall of the high-rise building in 2013 makes us show the horror of fire intelligently. If the glass of the burning building is fireproof, it can effectively prevent the extension and penetration of fire and smoke into the building, prevent the general window glass from becoming the burning channel of fire after being split by fire, cause internal fire and develop into a composite three-dimensional fire, and ensure the life and industry inside the building.

        In fact, the contact between this kind of thermal insulation material and fireproof glass window has been preliminarily popularized. Only in terms of skills and methods, we should focus on the fire rating, height and application of different buildings, China's national conditions and the current situation of industrial skills of external wall thermal insulation materials. When vigorously promoting the construction and emission reduction, we should select a variety of skill combination methods to reach the corresponding fire rating.

        In addition, it is assumed that there is no wall between windows and sill wall in the construction of floor external windows. In order to prevent the extension between floors in case of fire, a restraint with fire resistance function of no less than 1 hour shall be set. When it is required to set fire isolation belt, thermal insulation materials with width not less than 300mm shall be set along the floor direction. The fireproof isolation belt and the wall shall be stacked and posted.

        Thermal insulation materials, whether external walls or internal walls, qualified fire-proof and thermal insulation materials and useful fire-proof layout system can effectively control the extension of fire, reach the fire-proof standard of thermal insulation materials stipulated in Gongtong Zi [2009] No. 46 document jointly issued by the Ministry of public security and the Ministry of housing and urban rural development, and can adhere to the weather resistance under the high temperature of 1200 degrees. In addition, the fireproof glass window can basically block the extension of fire and make it seamless and pluggable.
