ABSTRACT: 为研究粘结压实药柱的解体与强度之间的关系及表层处理方法对解体与燃烧渐增性能的影响,分别采用升温直接压实法及乙醇/丙酮高温热蒸汽软化法将预处理后的太根小粒药压实成高密度药柱,再进行表层处理,得到待测的压实药柱样品,利用材料试验机测试样品的常温压缩力学性能;进行中止燃烧实验,并用数据采集系统记录燃烧中止前燃烧室内的压力-时间曲线,分析样品的解体及渐增性燃烧性能。与升温直接压实法相比,高温醇酮蒸汽软化法制得的样品压缩力学性能增强,药粒分裂、解体相对压力区间展宽,燃烧较为平稳。经表层钝感处理后的样品,起始动态活性明显降低。结果表明:高温醇酮蒸汽软化法制得的样品在保持一定力学性能时内层药粒易于分裂。选择合理的表层处理方法能较好抑制粘结压实药柱起始阶段的动态活性,解体过程能得到较好的控制,具有较好的燃烧渐增性。
