日本现用的森林火灾器材,大体上有以下一些。一、化学灭火剂 1.MAP化学灭火剂 MAP是亚磷酸铵的简称。粉状易溶于水,使用方便,即使在水源不足的情况下,也可以直接用粉末灭火,其灭火效力不减。MAP原系一种肥料,对动植物无害,它的灭火原理有2。 1)MAP在166℃时分解,呈吸热反应。因热分解而产生不燃气体,在可燃物周围形成气体层,使氧气与可燃物隔离。 2)在加热到216°—360℃时能生成焦磷酸,偏磷酸呈水雾状,覆盖在燃烧面上,可以阻隔氧的供给,熄灭燃烧着的可燃
Japan’s current forest fire equipment, in general, the following. First, chemical fire extinguishing agent 1.MAP chemical fire extinguishing agent MAP is short for ammonium phosphite. Powder easily soluble in water, easy to use, even in the case of insufficient water can also be directly used powder fire extinguishing, fire extinguishing efficiency diminished. MAP is a former fertilizer, harmless to animals and plants, its principle of fire there are 2. 1) MAP decomposed at 166 ° C, showing an endothermic reaction. Due to thermal decomposition of non-combustible gases, the formation of gas around the combustible material layer, so that oxygen and combustible material isolation. 2) when heated to 216 ° -360 ° C can generate pyrophosphate, metaphosphoric acid was mist, covering the combustion surface, you can block the supply of oxygen, burning off flammable combustible
