摘要
纵火案件现场非常复杂,火场大部分助燃剂易挥发并易受污染,给火场可燃物中助燃剂和其它相关物质的检验与认定带来困难。金属材料在火场中发生的物理化学变化,与火灾损伤评估密切相关,有望为纵火案调查提供可靠的科学依据。选择典型汽油、煤油、丙酮及乙醇作为引火物,利用燃烧环境气氛模拟系统,研究液体燃料在不同环境压力条件下的燃烧特性,以及金属、合金在该复杂燃烧气氛环境中的高温氧化行为,将有助于发展和完善金属材料在火场中燃烧产物的评估方法。
Arson scene is very complex, fire accelerant is most volatile and vulnerable to pollution, to examine and identify the accelerant fire combustible materials, and other related materials, which are difficult. Physical and chemical changes occurring metallic materials in the scene, closely related to fire damage assessment, is expected to provide a reliable scientific basis for the arson investigation. Select a typical gasoline, kerosene, acetone and ethanol as firelighters, by combustion atmosphere simulation system to study liquid fuel combustion characteristics under different environmental stress conditions, as well as metals / alloys in high temperature oxidation behavior of the complex combustion atmosphere environment, the contribute to the development and improvement of metallic materials in the product evaluation methods of fire.
