摘要:: 文章探讨了不同添加剂对提高粉状乳化炸药储存稳定性的作用。试验发现，滑石粉可以有效地减少粉状乳化炸药的结块现象，提高储存稳定性。当粉状乳化炸药水分质量分数较低时，作为硝酸铵晶型抑制剂的硝酸钾能有效地抑制粉状乳化炸药的结块现象。采用聚异丁烯醇胺型乳化剂（PIBSA-TEA）能提高粉状乳化炸药的储存稳定性，如果将其和聚异丁烯丁二酰亚胺乳化剂（T152）复配使用效果更佳。在油相添加一定质量的松香能延长炸药储存期，但加入量太高，生产过程中脱水困难，效果下降。

Abstract:: This paper discusses the effect of different additives in the role of improving the storage stability of pow dery emulsion explosives. In experiments, it was found that talcum powder could improve the storage stability by effectively reducing the agglomerate. At lower water contents, potassium nitrate, as the ammonium nitrate crystal type inhibitor, could effectively inhibit agglomeration in powdery emulsion explosive. Using polyisobutene alcohol amine (PIBSA-TEA) emulsifier can also improve the storage stability of powdery emulsion explosive, and the effect is better when it was used compound with polyisobutylene succinic imide (T152) emulsifier. Addition of a certain amount of rosin in the oil phase can prolong the storage time of explosives. But when the rosin addition is too high, the dehydration will become difficult in production process and the effect will decline.
