摘要:
探讨了硝酸钾抑制硝酸铵ANⅣ～ANⅢ相变的效应，并且研究了其在提高粉状炸药抗结块性中的作用。通过DSC、高低温试验和抗压强度测试证实，在硝酸铵中添加2%硝酸钾能完全抑制硝酸铵的ANⅣ～ANⅢ相变，能够提高粉状乳化炸药中硝酸铵的结晶稳定性，降低药体的抗压强度，有效地减少结块现象。
Abstract:
This paper studies the effect of potassium nitrate (KNO3) on inhabiting the ANⅣ～ANⅢ phase transition of ammonium nitrate (NH4NO3) and its application on improving anti-caking property for powdery emulsion explosive. Experiment results from differential scanning calorimetry (DSC), high-low temperature and compressive strength test show that the addition of 2% KNO3 could inhabit ANⅣ～ANⅢ phase transition totally, improve the crystallization and thermal stability of NH4NO3, reduce the compressive strength of powder emulsion explosive and resolve its caking phenomenon effectively.
