(1)闪燃 如果给可燃性固体或液体的表面加热到一定程度,可燃物就会发出火焰,我们把这种现象就叫做闪燃。例如给木材加热,当温度上升到170—180℃以上时,木材就会以很大的速度发生热分解,产生CO、CH_4、C_2H、H_2、有机酸、乙醛等可燃性气体和CO_2、H_2O等不燃性气体,再继续加热到一定温度,就产生燃烧,这表明该温度下木材热分解产 (1) flash fire If the flammable solid or liquid surface heated to a certain extent, flammable materials will be issued a flame, we call this phenomenon flash. For example, if the wood is heated, when the temperature rises to over 170-180 ° C, the wood will decompose rapidly at high speed to produce combustible gases such as CO, CH 4, C 2 H, H 2, organic acids, acetaldehyde and CO 2, H 2 O Such as non-flammable gas, and then continue to heat to a certain temperature, it produces combustion, indicating that the temperature of the wood thermal decomposition
