摘要
地板的燃烧性能对室内火灾的发展蔓延及火灾危害都有重要的影响,本文使用锥形量热仪对市场上常见几种地板(实木地板、竹制地板和复合地板)的燃烧性能进行试验研究。实验结果表明,地板的热释放速率具有两个峰,相同辐射功率下,竹地板和实木地板的比消光面积分别比复合地板高29.3%、42.5%,竹制地板点燃时间较小,复合地板火灾危险性要小于竹制地板和实木地板。
Flammability of floor coverings is highly relevant to the in do or fire spread and the fire hazard. Experimental study was carried out on the fl ammability of various floor coverings, including wood floor, bamboo floor and co mpound floor, by means of Cone Calorimeter. Experimental results show that the f loor heat release rate (HRR) curve has two peaks under the same radiation, the s pecific extinction area (SEA) values of bamboo floor and wood floor are respecti vely 29.3% and 42.5% higher than the value of compound floor, and the ignition t ime of bamboo floor is the shortest. It is concluded that the fire hazard of compound floor is the lowest among the three floor coverings.
