饰面材料对火灾冷热气层分界面的影响

摘要

采用ISO 9705标准全尺寸单室火灾实验方法,对3种常用的饰面装饰材料的单室火灾进行实验研究,实时测量地面辐射强度、室内和开口部位不同高度的温度随火灾变化的情况,分析装修材料对室内火灾的影响,测算轰燃时间以及冷热气层界面位置的变化,为火灾预防和扑救提供参考.%In this study, the ISO-9705 room was used to investigate the enclosure fire decorated with three traditional lining materials. The flame radiant intensity at the floor center, and the temperature distributions at the corner of enclosure and doorway at different heights were measured. The influences of decoration materials on the enclosure fire development were studied. The flashover time and the varied positions of the interface layer between the hot air layer and the cold air layer were evaluated to provide the experimental data for references of relevant fire prevention and fire fighting.
