粉状乳化炸药作为工业炸药重要品种之一,在工程爆破、爆炸焊接等领域被广泛应用,但在生产工艺中,喷雾干燥后往往存在着炸药粘壁和结块问题,严重影响粉状乳化炸药的生产效率和安全性。为解决粉状乳化炸药生产中的粘壁问题,分析炸药生产中粘壁问题的成因,探讨粘壁问题的表征和评估方法,同时,从改变配方组分、改进工艺条件、调整生产流程和使用添加剂等4方面,讨论解决粘壁问题的技术途径及可行性,为我国粉状乳化炸药存在的粘壁问题提供解决思路。

As one of the important varieties of industrial explosives, powdery emulsion explosives are widely used in engineering blasting, explosive welding and other fields. However, in the explosive production process, there are often problems of wall deposition and lumping after spray drying, which seriously affects the production efficiency and safety. In order to solve the problem of wall deposition in the production of powdery emulsion explosives, the causes are analyzed, and characterization and evaluation methods are discussed. At the same time, the technical feasibility ways to solve this problem are discussed from four aspects: changing the formula composition, improving the process conditions, adjusting the production process and using additives. It provides a solution to the problem of wall deposition in production of powdery emulsion explosives in China.
