Problems solved by technology

[0002] Explosives can be used in the military as explosive charges for shells, aerial bombs, missiles, mines, torpedoes, grenades and other ammunition, as well as detonating devices for nuclear bombs and military blasting. They are widely used in mining, road construction, and water conservancy construction in industry. , engineering blasting, metal processing, etc., are also widely used in scientific and technological fields such as seismic exploration. In the field of explosives analysis, due to the rapid development of modern analysis technology, the detection breadth, accuracy and analysis efficiency have been qualitatively improved. However, the sample The preparation technology, especially the separation and extraction technology of organic components has been stagnant and has become a bottleneck restricting the analysis process. With the rapid development of the national economy, the composition of new explosive products is becoming more and more complex
