为提高利用光敏炸药加载冲击载荷时的载荷精度
针对自研的喷涂系统
深入研究光敏炸药的喷雾沉积分布规律。获取不同喷涂距离(10cm、15cm、20cm)下光敏炸药喷雾沉积效率、喷雾宽度、喷雾面密度分布与喷涂距离之间的关系
拟合得到光敏炸药喷雾沉积分布规律方程;基于喷雾分布模型及喷雾叠加原理
开展平板均匀性喷涂及同步起爆验证性实验研究。研究结果表明:喷雾分布呈中间高两边低的规律
随着喷涂距离的增加
有效喷雾宽度逐渐增加
沉积效率逐渐降低;通过合理规划喷涂路径
可实现平面均匀性喷涂
测量得到的光敏炸药涂层面密度与设计值最大偏差为3%;光敏炸药起爆最大不同步时间为8.52μs;研究成果为今后光敏炸药精密加载技术的应用奠定了基础。
To improve the precision of impact loads when applying loads via light-initiated explosives
the spray deposition distribution patterns of light-initiated explosives are studied using a specially designed spray coating system.The relationships among spray deposition efficiency
width
areal density distribution
and spraying distance at different spraying distances (10cm
15cm
and 20cm) are obtained.An equation describing the spray deposition distribution pattern of light-initiated explosives is obtained through fitting.The uniform spray coating on flat surfaces and the synchronous detonation verification are is experimentally studied based on the spray distribution model and spray superposition principle.The research results indicate that the spray distribution follows a pattern of being higher in the middle and lower on both sides.As the spraying distance increases
the effective spray width gradually widens
while the deposition efficiency decreases.The uniform spray coating on flat surfaces can be achieved by rationally planning the spray coating path.The maximum deviation between the measured areal density and the design value of the light-initiated explosive coating is 3%.The maximum asynchronous initiation time of light-initiated explosives is 8.52μs.This research lays a foundation for the future application of precise loading techniques for light-initiated explosives.

DOI: 10.14077/j.issn.1007-7812.2018.06.007 http://doi.org/10.14077/j.issn.1007-7812.2018.06.007 A light-ignition explosive, silver acetylide-silver nitrate (SASN), was synthesized using silver nitrate and acetylene as raw materials. The effects of reaction temperature, silver nitrate concentration and additives on the synthesis process were analyzed and the optimum synthetic process was obtained. The particle size, composition and thermal decomposition properties of SASN crystal were studied by scanning electron microscopy(SEM), XRD and DSC, respectively. The kinetic parameters of thermal decomposition reaction of SASN were obtained by Kissinger’s method and its sensitivities to impact, friction, flame and electrostatic spark were measured. The results show that the morphology and size of SASN particle are easily influenced by the synthetic conditions. Most particles of SASN are long needle-shaped crystals, the length is between 10 and 60 μm. The optimum synthetic conditions are as follows:when the reaction solution is 25 g of silver nitrate, 150 mL of water, 29 mL of nitric acid, the yield obtained is higher,which reaches 86.1%. At a heating rate of 10℃/min, the decomposition peak of SASN is 232.9℃. The apparent activation energy of thermal decomposition of SASN obtained by Kissinger’s method is 121 kJ/mol. Its characteristic drop height, flame sensitivity and electrostatic spark sensitivity are 23.9 cm, 23.9 cm and 0.49 J, respectively, which is more insensitive than pure lead azide (LA). Its friction sensitivity is 80%, which is more sensitive than LA.
