摘要
运用热重法 (TG)及差示扫描量热法 (DSC)研究了不同钝感剂种类及浓度对钝感发射药的热分解性能的影响。以 TG曲线和DSC曲线的临界热分解温度来定性地表征钝感发射药的点火难易程度 ,传统观点认为发射药经钝感处理后其点火温度应当升高 ;而实验结果表明对于本文所述钝感剂及其不同浓度处理的钝感药 ,其 TG曲线和 DSC曲线的临界热分解温度并未升高 ,而是略有下降 ,DSC曲线的吸热量有显著的降低 。
In this article, a study on the thermal decomposition and the ignition behavior of deterred powder penetrated by variety of deterrents wity the different concentration is conducted through the Thermogravimetry (TG) and Differential Scanning Calorimetry (DSC). The threshold thermal decomposition temperature of TG and DSC curves could qualitatively characterize the ignition properties of the deterred gun propellant. The traditional viewpoint is that the ignition temperature should increase, but the experimental results show that for the kind of deterrents and their concentration using in this experiments, the threshold thermal decomposition temperature of TG curves and DSC curves doesn't increase, but decreases little, and the endotherm amount of DSC curves decrease obviously. The brief analysis on the experimental results is presented.
