香烟引燃特性的实验研究

Experimental study of the cigarette ignition characteristic

通过香烟火源引燃几种家庭常见物品的实验,研究香烟火的引燃特性。实验结果显示:香烟火温度虽高,但不一定引起有焰燃烧,可能只有炭化痕迹或持续阴燃;判断材料有无蓄热能力,不能只考虑材料自身组分的燃烧特性,而是要具体问题具体分析;蓄热材料也不一定能被香烟火点燃;阴燃反应相对缓慢,产生较多有毒气体,没有火焰,潜伏期长,不易察觉。

Study the ignition characteristics of cigarette fire by experiments of igniting several common household items,and get the following conclusions： Though the temperature of cigarette fire is high,flame burning is not necessarily,and there may only be trace of carbonization or sustained smoldering;whether the material have thermal storage capacity depends not only on the combustion characteristics of material itself,but also on the specific issues;thermal storage material may not necessarily be lit by the cigarette fire;smoldering reaction is relatively slow,resulting in more toxic gases,no flame,long incubation period,and is difficult to detect.
