Research on new intelligent non-primary electronic detonator

Industrial electronic detonators are usually filled with relatively sensitive detonation agents, which makes electronic detonators in the production and application process, prone to accidental explosion, there is a certain safety risk. Target:In order to meet the needs of industry safety and market, this paper studies a new no-primary electronic detonator. Methods: The main methods used were theoretical analysis of working mechanism, numerical simulation of blade speed, high-speed photography and underwater explosion test methods for product initiation capability.Conclusion:The rationality of its structure is proved through a series of tests. If the lead plate perforation test shows that the electronic detonator is 400mg, the second main charge is 200mg, and the third main charge is 320mg, The pressure density is 1.56 g/cm³, At the pressure density of the second load is 1.41 g/cm³, Three-pack in bulk, The detonation transmission of the detonator is relatively stable, Can form a stable detonation; In contrast with the traditional nonexplosive detonator, It shows that the axial detonator of this structure is large; The closing diameter of the pilot generator is controlled in the 5.6~5.7mm range, Can realize the combustion to detonation and obtain a reliable detonator flying speed. The product structure design of the study eliminated four drugs compared with the traditional detonator structure, which both simplifies the production process and improves the safety. The rationality and advantages of the structure are verified by lead plate test and underwater explosion test.
