液化石油气易燃易爆的特性主要表现

[ 2011-7-21 15:47:00 | By: 杨远锋 ]

(1)液化石油气沸点低，在常温常压下极易汽化，1 m3液体可汽化250 m3气体。
(2)液化石油气气态比空气重，能飘浮在地面或在低洼处沉积，而不易扩散。
(3)液化石油气的爆炸下限低，当液化石油气在空气中的浓度达到1.5%时，就能形成爆炸性气体。
(4)液化石油气的点火能量小（小于0.4mJ），只要有极微小的火星就可引燃引爆。
(5)液化石油气的电阻率高，高速从容器中喷出时能产生数千伏以上的静电电压，其放电火花足以引起着火爆炸。
(6)液化石油气中含有硫化物，能腐蚀容器产生硫化亚铁粉末，遇空气会放热自燃。
