摘 要:对不同导热系数的挤塑板开展试验研究,获得其燃烧速率增长指数、600s内总热释放量、600s内总产烟量、烟气生成速率指数、火焰横向传播等关键参数,探讨不同导热系数的挤塑板的燃烧性能。研究表明:挤塑板遇火迅速熔融,并产生燃烧滴落物。在本文的试验中,导热系数小的挤塑板发生剧烈的燃烧现象并产生大量的烟。导热系数较大的挤塑板则具有较好燃烧性能。Abstract: This paper presented an experimental investigation on XPS with different thermal conductivity. Through the FIRGA, THR60Os, TSP60Os, SMOGRA, LFS and other parameters obtained from the experiment, the combustion performances of XPS with different thermal conductivity were then analyzed. The study concludes as follows: The XPS became rapidly molten under fire with flaming droplets in the combustion process. It is also proved that the XPS with lower thermal conductivity burnt heavily and produced lots of smoke, while the XPS with larger thermal conductivity had better combustion performance.
