许多私人和公共部门的计划都有开发一种从种类上称之为固体微粒气溶胶的新型灭火剂项目。该灭火剂容积效率高，初始成本和生命周期成本低，毒性低，对全球大气环境无已知不良影响，在许多领域都有潜在的应用价值。现在，研究人员正在研制那种一被点燃即可产生比空气轻的高效灭火气溶胶的固体化合物的配方。初始数据表明，这种气溶胶的灭火效力是哈龙１３０１的４倍。利用固体、凝胶或粉末作起点来生成气溶胶可以省掉管道和耐压钢瓶，因此在众多消防场合都有潜在的应用价值。这些场合包括公用设施、飞机用装货容器、便携式速建棚屋、燃料贮罐、蓄电池／连续供电电源系统机房、无人通讯设施以及装甲车发动机室等。气溶胶形成的速率取决于系统的设计和配置。本文将介绍气溶胶的灭火机理和最近的试验结果。
Many private and public sector programs have developed a new type of fire extinguishing agent projected as a type of solid particulate aerosol. The fire extinguishing agent has high volumetric efficiency, low initial cost and life cycle cost, low toxicity, no known adverse impact on the global atmosphere, and has potential application value in many fields. Researchers are now developing a formulation that will ignite solid compounds that produce lighter, more efficient aerosols than air. The initial data shows that this aerosol has four times more fire extinguishing power than the halon 1301. The use of solids, gels, or powders as a starting point to generate aerosols can eliminate piping and pressure-resistant cylinders, and therefore has potential application value in many fire-fighting situations. These occasions include public facilities, aircraft loading containers, portable speed sheds, fuel storage tanks, battery/continuous power supply system rooms, unmanned communication facilities, and armored vehicle engine rooms. The rate of aerosol formation depends on the design and configuration of the system. This article will introduce the fire extinguishing mechanism of aerosols and recent test results.
