为全面揭示全氟丁基甲醚的灭火反应路径,采用试验与理论相结合的方法,研究全氟丁基甲醚的灭火性能与灭火机制.首先通过杯式燃烧试验,评估全氟丁基甲醚的灭火性能;然后利用气体高温热解机制分析平台,模拟其高温热分解过程,并借助气相色谱-质谱联用仪分析不同温度作用下的热解产物.研究发现,全氟丁基甲醚的临界灭火体积分数约为5.90％,灭火性能良好;其初始热分解温度为400℃,热解产物包括九氟-1-丁烷、八氟-1-丁烯、六氟丙烷和三氟甲烷.试验结果说明:全氟丁基甲醚可成为哈龙灭火剂的替代物.
Fire extinguishing performance and fire extinguishing mechanism of perfluorobutyl methyl ether
In order to comprehensively reveal the fire-extinguishing reaction path of perfluorobutyl methyl ether,its fire extinguishing performance and fire extinguishing mechanism were investigated by combining experimental and theoretical methods.The fire extinguishing performance of perfluorobutyl methyl ether was evaluated by cup combustion test,and its high-temperature thermal decomposition process was simulated by a gas high-temperature pyrolysis mechanism analysis platform,and the pyrolysis products at different temperatures were analyzed by gas chromatography-mass spectrometry.It was found that the critical fire extinguishing volume fraction of perfluorobutyl methyl ether was about 5.90％,and the fire extinguishing performance was good.The initial thermal decomposition temperature of perfluorobutyl methyl ether was 400 ℃,and the pyrolysis products include nonafluoro-1-butane,octafluoro-1-butene,hexafluoropropane and trifluoromethane.The test results revealed the fire-extinguishing mechanism of perfluorobutyl methyl ether,indicating its potential to become a substitute for halon fire-extinguishing agents.
