摘要:采用差示扫描量热仪(DSC)和小型密闭爆发器装置,研究了KP对RDX/NC、HMX/NC和NQ/NC 3种硝胺体系火药燃烧性能的影响。实验证明:含有KP的3种硝胺体系火药中各组分热分解具有较好的相对独立性,具有较高火焰感度的KP能够调整3种硝胺体系火药热分解行为,改善火药的点火性能,提高火药的燃烧速度。
Abstract:The effects of potassium picrate on the combustion property of nitramine type powder containing RDX/NC,HMX/NC and NQ/NC were carried out by DSC and closed bomb tests. The results show that each component in the nitramine type powder containing potassium picrate, to some degree, can be decomposed independently, the potassium picrate with high flame sensitivity can adjust the thermal decomposition behavior of nitramine powder,improve the ignition property of nitramine powder and raise the combustion rate of nitramine powder.
