Beijing, 100040 [ABSTRACT] Through the charge-pressing floating test and fluxion property determination of initiating charge in organic glass shell, it is found that reduction of loading performance, bad fluxion property and easy floating of charge-pressing would occur with the increasing of mass fraction of particles with grain size less than 45μm in spherical dextrin lead azide. It is also found that charge-pressing floating will be caused by frequently burst pressure and instantaneous-explosion of MS delay electric detonator. Two quantity control indexes were proposed including bulk density≥ 2. 00 g/ cm3, and mass frac- tion of particles with grain size less than 45 μm ≤20%. Preparation process is as follows 3% mass fraction sodium nitrite solution is added into 8% mass fraction lead nitrate solution, the mass ratio of water and charge is 30︰1, addi- tional amount of industry acidity dextrin is 5% mass fraction , alkalinity of sodium nitride solution is 0. 080%, and the certain feeding speed and stirring intensity are maintained at the temperature of 60℃. The manufactured initiating charge can meet the requirements of detonator assembly.
