膨化硝酸铵的感度特征研究

Research on Sensitivity Characteristics of Expanded Ammonium Nitrate

膨化硝酸铵是近年来得到广泛使用的工业炸药氧化剂。本文对其撞击感度 ,摩擦感度 ,爆发点 ,火焰感度 ,静电火花感度等危险感度进行了测定 ,并对膨化硝酸铵进行了 DSC实验 ,以及对雷管感度及冲击波感度等实用感度进行了测定。研究表明 ,同普通硝酸铵相比 ,膨化硝酸铵具有较低的危险感度及良好的实用感度。

Expanded Ammonium Nitrate is widely used as oxidizer of industrial explosive in recent years. In this paper, dangerous sensitivities of expanded Ammonium Nitrate including sensitivity to impact, sensitivity to friction, sensitivity to flame, ignition point, sensitivity to electrostatic spark are tested, and DSC experiment was done practical sensitivity of expanded Ammonium Nitrate such as sensitivity to detonator, sensitivity to shock wave are tested. The results show that expanded Ammonium Nitrate has lower dangerous sensitivities and better practical sensitivities compared with common Ammonium Nitrate.
