摘要:
为了研究3,4-二硝基呋咱基氧化呋咱（DNTF）自身及奥克托今（HMX）、铝(Al)粉、高氯酸铵(AP)、聚叠氮缩水甘油醚（GAP）和蜡等添加物对DNTF炸药凝固温度的影响规律，采用微热量热法研究了三硝基甲苯(TNT)、2,4-二硝基苯甲醚(DNAN)、DNTF在程序降温时凝固温度的差异；采用显微镜动态观测了不同温度下DNTF样品的凝固过程，计算了样品的凝固线速率，分析了试样动态凝固过程特征；采用微热量热法研究了HMX、铝粉、AP、GAP和蜡对DNTF凝固温度的影响规律；结合添加物对DNTF基混合炸药凝固温度的影响规律，设置不同壳体温度,研究了预热温度对装药质量的影响规律。结果表明，相比于传统TNT、DNAN具有基本稳定的凝固温度，DNTF凝固温度波动较大；随着凝固温度的升高，DNTF微观凝固界面由平滑状态逐渐变化为柱状生长，凝固线速率先增大、后减小；HMX、铝粉、AP、GAP和蜡均促使DNTF凝固温度集中在83～92 ℃左右；壳体预热温度达到85 ℃，DNTF基混合炸药的装药质量明显提高。
