近年来,因装饰材料易燃而引起的火灾时有发生。为此,世界上不少厂商都在致力于开发可阻燃防火的装饰材料。 防火木制窗框 日本富士山市木窗公司开发出一种防火木制窗框,其周围嵌有密封材料,遇热膨胀,能防止火焰从缝隙钻入,即使屋外大火燃烧很猛,它也可耐火30min。这种窗框用松木制成,四周粘贴用石墨制成的密封材料,堵住细微缝隙,增加防火效果。据试验,在距离该窗框10cm处,用喷火器对准窗框喷出温度达800℃的火焰.历时20min,火焰也未能透过窗框,故防火效果是铝制窗框
In recent years, fires caused by flammable decorative materials have occurred from time to time. To this end, many manufacturers in the world are working hard to develop flame retardant decorative materials. Fireproof wooden window frames Japan’s Fujisan City Wooden Window Company has developed a fireproof wooden window frame with sealing material embedded around it. When it expands due to heat, it can prevent the flame from entering through the gap. Even if the fire outside the house burns fiercely, it can also be fire-resistant. 30min. This type of window frame is made of pine wood, and the sealing material made of graphite is attached around it to block the fine gaps and increase the fireproof effect. According to the test, at a distance of 10cm from the window frame, the firearm was used to align the window frame with a flame with a temperature of 800°C. After 20 minutes, the flame failed to pass through the window frame, so the fireproof effect was an aluminum window frame.
