摘要
针对废弃丁羟推进剂(HTPB)韧性强和感度高的特性,在保证试验过程安全的前提下,分别研究了湿式笼式粉碎法、干式旋风切削法和远程控制切割法这三种方式粉碎废弃HTPB。结果表明:以粉碎比(即进料直径与出料直径之比)和AP、Al的损失率为评价标准,干式旋风切削法粉碎后的物料直径最小约为1mm,有效成分损失率低于1.4%,由其制备的工业炸药可被8#雷管引爆,验证了该方式粉碎HTPB较为理想。
Three cutting machines were selected to study the comminution of HTPB,including cage wet grinder,dry cyclone and long-range control cutting machine.Using diameter ratio and loss rate of AP and Al as standards,dry cyclone is comparatively smashed method at present.The diameter of smached materials was about 1 mm,8# detonator could be ignited by the commercial explosive prepared with the materials.
