Abstract:

为了改善微气孔球形药的传火特性,采用浸渍的方法在药粒表面及内孔中吸附不同种类的敏化剂,研究敏化剂种类和添加量对微气孔球形药热分解特性和传火速度的影响。结果表明,敏化剂的引入可以降低样品的热分解峰值温度,在所选的几种敏化剂中敏化剂A对样品热分解峰温的影响最显著。在单基型微气孔球形药中添加5%的敏化剂A,其热分解峰值温度从203.1℃降低到199.5℃;在装填条件下,不同种类的敏化剂均可提高药粒的传火速度,传火速度随着敏化剂添加量的增加而提高;在所选的几种敏化剂中,敏化剂C对单基微气孔药的传火速度影响最大,添加5%的敏化剂C可使样品的传火速度提高近3倍。当添加敏化剂A时,单基微气孔药传火速度的提高幅度明显高于双基型微气孔药;敏化剂A对单基微气孔药的撞击感度影响不大,当添加量小于16%时,撞击感度的变化幅度不超过10%,摩擦感度则随敏化剂添加量的增加逐步提高,当添加量达到16%时样品的摩擦感度可以从58%提高到98%。引入敏化剂来改善微气孔球形药的传火特性是有效的,但添加量不宜太大,否则会对样品的安全性能带来负面影响。
