Study On The Storage Stability Of Nitrate Explosive

The decomposition mechanism of nitrate explosives is rather complicated. It includes the self decompositionthe, Self forcing decomposition, the hydrolysis function and the thermal decomposition. The nitrate explosives carry out the thermal accelerating aging test based on the test and analysis of the critical storage temperature.In the formula design of nitrate explosives, the compound of stabilize conducive to its safe storage. The critical storage temperature of RDX-based Nitrate Explosive is 199.22. The critical storage temperature of HMX-based Nitrate Explosive is above 200.So that whether using the 71 GJB736.8-1990 test or propellant storage life test for nitrate explosives is safe relatively.It chooses the 71 of single factor for carrying out the accelerated storage test.By studying the change of the mass loss rate, the volume change rate, the vacuum stability and the stability of the RDX-based Nitrate Explosive,the storage life at 21 can achieve 12 years of tactical indicators.It chooses the 71 of single factor for carrying out the accelerated storage test. By studying the change of shockwave sensitivity, explosion heat, density, impact sensitivity and friction sensitivity of the HMX-based Nitrate Explosive, the storage life at 21 can achieve 12 years of study indicators.It chooses the four step temperature for carrying out the accelerated storage test. By studying the change of the stability and mechanical property of the HMX-based Nitrate Explosive and using the linear regression analysis of Bethelot equation, the safe storage life at 30 is 15.
