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, but 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
[0003] With the development of blasting technology and civil explosive equipment, users need blasting equipment with multiple varieties, specifications and different physical forms. High-hardness explosives can resist large contact deformation. At present, high-hardness explosives are widely used in explosive processing, welding and special blasting fields. Wide range of demands, such as in blasting engineering, high hardness as a support can withstand greater pressure without deformation. Since the 1980s, my country has developed rapidly in the development of civilian blasting explosives, and has successfully developed many special properties. However, there are not many reports on high-hardness explosives and their preparation methods
