摘要(Abstract)：

将聚能式超声波引入RDX（黑索今）的驱酸洗涤过程，研究超声对含酸RDX晶体的驱酸洗涤效果和声学作用机理。探讨了RDX晶体含酸机制，分别考察了超声时间、超声温度、超声频率、超声功率等参数对RDX酸度的影响规律，运用扫描电镜（SEM）观察了超声前后RDX颗粒微观结构的前后变化。结果表明：晶间酸是RDX酸度偏高的主要原因；超声作用可明显缩短RDX驱酸洗涤所需时间；超声温度和超声功率设置对RDX酸度的影响存在一个最优值，并非越大越好；相比于40 kHz，25 kHz低频超声的强化驱酸洗涤效果较好；超声作用后的RDX酸度远低于GJB指标要求，产品质量良好，由此表明将聚能式超声清洗技术用于RDX驱酸洗涤过程，是降低RDX晶体酸度的一种行之有效的方法。
