Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of civilian explosive equipment, and in particular relates to an explosive device for detecting solid residues after explosion and a use method thereof. Background Art
[0002] In order to strengthen the control and security inspection of explosives in my country, effectively prevent and deter the occurrence of terrorist bombings, and accelerate the handling of terrorist bombings, the key is to add traceable substances (markers) into the finished explosives and trace the source of the explosives through special detection methods. However, the instantaneous high-temperature and high-pressure gas generated after the explosion of explosives and the influence of the surrounding environment make the detection of markers a difficult point.
[0003] The currently common closed explosive devices have a small explosion resistance and low content of markers, making it difficult to obtain representative samples. Other explosion-proof containers for transportation are mostly transport detonators, and their explosion resistance is not enough to withstand the equivalent of the smallest package of general industrial explosives. At the same time, when the above-mentioned explosion-proof containers are depressurized after the explosion, the airflow generated will spray the markers to be detected out of the container, resulting in the phenomenon that they cannot be detected. Summary of the invention
