摘要:
为探究含不同性质添加剂的水雾对单基火药燃烧抑灭性能的影响，在自主搭建的火药燃烧及灭火平台上开展纯水雾与含Na2SO3、FeCl2、K2CO?2024/6/3、KHCO3添加剂的水雾对单基火药燃烧抑灭性能的对比实验，研究灭火过程中温度、辐射热流、火焰形态等的变化。结果表明：含还原性（Na2SO3、FeCl2）和非还原性（K2CO3、KHCO3）添加剂的水雾抑灭性能明显优于纯水雾，灭火时间更短。含非还原性添加剂的水雾在低浓度下抑灭效果较差，当添加质量分数提升至3%以上时，抑灭效果显著提升；含还原性添加剂水雾对单基药的抑灭性能在各添加剂浓度下均优于含非还原性添加剂的水雾，且随着添加剂浓度的增大，抑灭性能表现出饱和性。
Abstract:
In order to investigate the influence of additives with different properties on the fire suppression performance of water mist on single base propellant, a comparative experiment of single base propellant combustion and suppression was conducted on a self-built platform. It compared the performance of pure water mist and water mist containing Na2SO3, FeCl2, K2CO3 and KHCO3 additives in suppressing the combustion of single base propellants. Changes in temperature, radiant heat flux, and flame morphology during the fire suppression process were studied. The results show that the fire suppression performances of water mist containing reducing additives (Na2SO3, FeCl2) or non-reducing additives (K2CO3, KHCO3) are significantly better than that of pure water mist, with shorter extinguishing time. The performances of water mist containing non-reducing additives in suppressing single base propellant fires is poor at low concentrations. When the mass fraction of nonreducing additives rises above 3%, the fire extinguishing ability is significantly improved. The fire suppression performances of water mist containing reducing additive are superior to that of water mist containing nonreducing additive at all concentrations. In addition, as the increase of the concentration of reducing additive, the fire suppression performance is saturated.
