Methods for Testing Explosive Residues of Pyrotechnic Powder
Explosion cases at home and abroad occur from time to time,seriously threatening the safety of people's lives and property,through the classification of a large number of explosion cases,it is found that pyrotechnic powder is a common explosive energy source in explosion cases.Due to the wide variety of pyrotechnic powder,the composition formula is even more diverse,and the reaction process is easily affected by external conditions,and the reaction products are also relatively complex,so it brings great challenges to the public security organs in the on-site investigation of pyrotechnic powder explosion cases,such as the analysis of the type,composition and source of pyrotechnic powder.On the premise of summarizing the common pyrotechnic powder explosion products,this paper summarizes the relevant literature on the detection methods of pyrotechnic powder explosion residues at home and abroad,summarizes and classifies the commonly used testing methods and their advantages and disadvantages,and hopes that the public security organs will provide some help for the analysis of the types,compositions,and sources of pyrotechnic powder in pyrotechnic powder explosion cases.
