一、引言化学灭火剂用于森林防火已有五十多年的历史,有关化学灭火剂灭火作用的机制研究,在国外已做了大量工作。如George和Susott用硫酸铵和磷酸铵处理纤维素,从热解和燃烧两个方面来研究,Batorewicz和Hughes用氧指数测定仪对作用机制的研究。特别是Sein——Satonako和Masatoshi Wada在热分解反应的流动系统中,对纯的磷酸氢二铵和硫酸铵进行差热分析,得出了磷酸氢二铵和硫酸铵的热解反应途径,为研究这两种化学灭火剂的灭火机制提供了可靠依据。六十年代以来,从事森林化学灭火药剂研究的专家和学者,对化学灭火药剂的化学作用机制研究较多,并从不同的研究角度提出了各种作用途径,然而,详细地探讨药剂的哪些成份对可燃物的哪些组分起作用报导甚少。为了提高化学灭火药
I. INTRODUCTION Chemical fire extinguishing agents have been used in forest fire prevention for more than 50 years. Research on the mechanism of fire extinguishing of chemical fire extinguishing agents has done a lot of work abroad. For example, George and Susott treat cellulose with ammonium sulfate and ammonium phosphate, studying both pyrolysis and combustion. Batorewicz and Hughes studied the mechanism of action using an oxygen indexer. In particular, Sein - Satonako and Masatoshi Wada conducted differential thermal analysis of pure diammonium hydrogen phosphate and ammonium sulfate in the pyrolysis reaction system. The pyrolysis reaction pathway of diammonium phosphate and ammonium sulfate was Study of these two kinds of chemical fire extinguishing agent provides a reliable basis for fire-fighting mechanism. Since the 1960s, experts and scholars engaged in the research of forest chemical fire extinguishing agents have studied chemical mechanism of chemical fire extinguishing agents for a long time and put forward various action channels from different aspects. However, Which components of combustibles play a very poor role has been reported. In order to improve chemical extinguishing drugs
