摘要:
为探究在高温下柔性有机堵料的热解特性及热解烟气成分，采用元素分析和热重(TG)分析测试方法，对2种柔性有机堵料的组成及热解性质进行对比研究，并通过烟箱和烟气分析仪模拟火灾中常见的热辐射环境，研究模拟火灾环境中2种柔性有机堵料有毒有害气体的释放情况及释放规律。研究结果表明：2种柔性有机堵料均有较好的耐火性能；在模拟火灾的热辐射环境中，2种柔性有机堵料均释放多种有毒有害气体，且大部分气体在受热辐射后10~75 min时间范围内释放，并主要集中在30~50 min时间范围内；2种柔性有机堵料样品所释放的气体组分种类大致相同但各组分含量有着较大的差异，可能与2种柔性有机堵料成分组成种类相似，但各组分含量比例不同有关。
Abstract:
In order to explore the pyrolysis characteristics and the pyrolytic smoke composition of flexible organic plugging materials at high temperature,the composition and pyrolysis properties of two kinds of flexible organic plugging materials were studied by the elemental analysis and thermogravimetric (TG) analysis methods.The common thermal radiation environment in fire was simulated by smoke box and smoke analyzer,and the release status and release law of toxic and harmful gases from two kinds of flexible organic plugging materials in simulated fire environment were studied.The results showed that both the two kinds of flexible organic plugging materials had good fire resistance.In the thermal radiation environment of simulated fire,both the two kinds of flexible organic plugging materials released a variety of toxic and harmful gases,and most of the gases released within the time range of 10~75 minutes after the thermal radiation and mainly within the time range of 30~50 minutes.In addition,the types of gas components released by the two kinds of flexible organic plugging materials were roughly the same,but the contents of each component were greatly different,which might be related to different content proportions of each component although the types of components of the two kinds of flexible organic plugging materials were similar.
