| 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 ANr- AN phase transition of ammonium nitrate （ NH4NO3 ） and its application on improving anti-caking property for powdery emulsion explosive. Ex- periment results from differential scanning calorimetry （ DSC）, high-low temperature and compressive strength test show that the addition of 2% KNO3 could inhabit ANn - ANm phase transition totally, improve the crystalhzation and thermal stability of NH4 NO3, reduce the compressive strength of powder emulsion explosive and resolve its caking phenomenon effectively. |
