【摘要】 对CO2惰性性质进行了探讨,从实验和理论两个角度论证了CO2灭天然气火灾时并非惰性,可以与天然气反应生成醇、醛、酮、酸;CO2与天然气的反应,一方面使CO2的灭火原理有了相应的改变、灭火效率降低;另一方面,反应产物有腐蚀性,介电常数下降。因此,CO2在消防中作为灭火剂的使用范围应做适当调整。更多还原

【Abstract】 This article studied the inert properties of CO2 and proved experimentally and theoretically that CO2 is not inert when it is used to extinguish a fire of natural gas because it can react with natural gas to form alcohol, aldehyde, ketone and acid On the one hand, such reaction may change the extinguishing principle of CO2 and lower extinguishing efficiency; on the other hand, the resultants of such reaction are corrosive and result in the decrease of dielectric constant Therefore, the using of CO2 as an extinguishing agent in fire fighting should be adjusted appropriately 更多还原
