摘要
膨化硝酸铵是一种改性硝酸铵晶体 ,具有显著自敏化特征 ,成功应用于各类膨化硝铵炸药及震源药柱中。在膨化剂 (表面活性剂 )的作用下改善了膨化硝酸铵的物理性能和晶体结构及其特征。本文通过硝酸铵固体表面接触角的测量 ,算出了膨化硝酸晶体表面能 ;利用差热分析 (DSC)技术给出了膨化剂对硝酸铵晶变的影响 ;
Expanded ammonium nitrate (AN) is a kind of new improved AN, possessing outstanding self sensitized characteristics, and is successfully applied to various kinds of expanded AN explosives and seismic explosive columns. Under the action of expanding agents (surfactants), its physical properties, crystalline structures and characteristics are remarkably improved. In this paper, through determination of solid surface contact angles, the surface energy of expanded AN crystal is calculated. Influence of expanding agents on crystalline change is obtained through DSC, and the crystal lattice characteristics of expanded AN are analyzed through SEM.
