乳化炸药不合格品返工工艺的研究

Research on the Rework Process of Unqualified Emulsion Explosives

文章利用"水中溶化固体物质后其溶液的沸点大于纯水的沸点"的这一原理,设计了一种在机械搅拌和切割的作用下利用临近沸点的热硝酸铵溶液对不合格乳化炸药进行加热破乳,以提高加热体系的温度和受热均匀性,然后再分液回收利用水、油相材料的乳化炸药返工处理工艺,并设计确定了破乳时硝酸铵水溶液的加入量和破乳设备的制作方案,对新工艺的破乳效果、安全性、返工产品性能的稳定性进行了分析和讨论。

Based on the principle that boiling point of the solution after dissolved solid materials in water is higher than that of pure water, a rework process of emulsion explosives is designed in this paper. The hot ammonium nitrate solu- tion near boiling point is used for heating and demulsificating the unqualified emulsion explosives by mechanical stirring and cutting, in order to enhance the temperature and heating uniformity. And then water and oil phase are recycled by skim- ming. The added amount of ammonium nitrate solution when demulsification and the production plan of demulsification e- quipment are comformed. The demulsification effects, safety, the stability of rework product performances are also analyzed and discussed.
