摘要
利用差示扫描量热仪(DSC)对钨系延期药进行了热分析研究,分析了钨系延期药的热分解特征和反应机理,并计算了热动力学参数。结果表明:钨系延期药热分解存在预点火反应,它降低了组分间的反应能垒,使一系列氧化还原反应更易于进行。
The thermal analysis of tungsten type delay composition was carried out using differential scanning calorimetry （DSC） in this paper.The thermal decomposition characteristic and reaction mechanism of tungsten type delay composition were studied and the kinetic parameters were calculated.The results showed that there was preignition reaction in the thermal decomposition of tungsten type delay composition,which reduced the reaction energy barrier among the ingredient and made a series of redox reactions much easier.
