PBXinitiationmechanical propertiesThe coefficient of friction, , of PBX 9404 was measured on stainless steel, aluminum, polytetrafluoroethylene (PTFE), and the explosive itself between ambient and 135°C at a rotational speed of 0.0025 rad/s. The mean surface roughness, Ra, of the various ...
PBX-9404炸药的冲击起爆过程. 2非均质炸药细观化学反应动力学模型 Kim…提出了非均质炸药冲击起爆的弹粘塑性球 壳塌缩模型,把如图1所示的典型塑料粘结炸药的细 观结构简化成如图2所示的球壳元胞模型.图中A 是炸药颗粒,B是粘结剂,C是空穴,P.是冲击波在炸 ...
In this report, the authors examine gaseous and aqueous products of base hydrolysis of the HMX-based plastic bonded explosive, PBX-9404. They also examined products from the subsequent hydrothermal treatment of the base hydrolysate. The gases produced from hydrolysis of PBX-9404 are ammonia, ...
摘要: Ideally, the breakout front should be completely straight and all points on the surface of the explosive charge should ignite simultaneously. TC-134 high-energy detonators were used & an inline CVR was used to record the current input to the detonators....
