【摘要】 为了考查几种点火药长期包装贮存的相容性,分别使用原始的、经过不同温度加速贮存的、库房内密封包装贮存的3种状态的点火药,通过差示扫描量热法、真空安定性法检测它们的相容性。同时研究了库房内密封包装贮存2.5a的点火药的相容性变化。研究结果表明:点火药在长期密封包装贮存期间,虽然其第1分解峰峰值温度之差小于5℃,然而由于分解的表观活化能改变率增大,其相容性也变差。更多还原

【Abstract】 The compatibility of the original ignition powder,the ignition powder stored at different temperature and the ignition powder in sealed package stored in storeroom were studied,by DSC and vacuum stability test.The research on the compatibility of the ignition powder in sealed package stored in storeroom for 2.5 years indicated that,although the temperature differential of the first decomposition peak was below 5℃,while the change rate of the apparent activation energy of decomposition increased,so the compatibility of ignition powder became worse.更多还原
