某型枪射催泪弹的可靠性研究

Study on the Reliability of a Gun Firing Tear Gas Grenade

为了对某型枪射催泪弹的可靠性进行研究,首先对其发射药的组分含量进行分析;然后对主装药各组分含量、在体系中的分散情况及安定性能进行了深入探讨;最后分别对主装药与铝和钢之间的相容性进行了测试。结果表明:发射药及主装药经5 a储存后,各组分含量的变化均在标准允许范围之内;主装药的SEM图表明,各组分经长期储存后依然分散均匀,没有出现明显的质变现象;不同升温速率下的DSC曲线中,主装药储存前、后的熔点和分解温度位移幅度小于2℃,安定性较好;主装药与铝和钢的DSC曲线上放热峰的微量变化也表明各自之间具有理想的相容性。以上研究表明:该型枪射催泪弹在使用年限内具有极高的安全性和可靠性。

In order to study the reliability of a gun firing tear gas grenade,composition content of the propellant was firstly analyzed.Then composition content and stability of the main charge and dispersion of each component in the system were discussed.Finally,the compatibilities of the main charge/Al and the main charge/steel"were tested,respectively.The results show that content variations of each component in propellant and main charge are maintained within the allowable range of the standard after storage of 5 years.SEM of the main charge shows that the components are still distributed uniformly after long term storage,and there is no obvious qualitative change.At different heating rates,DSC results show that stability of the main charge is superior in that the displacements of the melting and decomposition temperature between unstored and stored main charge are less than 2丈.Based on DSC curves of the main charge/Al and the main charge/steel,changes of the exothermic peaks are very small,so the compatibility is very ideal for the main charge/Al or the main charge/steel.Results above indicate that the tested gun firing tear gas grenade presents extremely high reliability and safety during lifetime.
