Problems solved by technology
[0007] In order to solve the problems existing in the existing Brinell pressure method technology, it cannot automatically monitor the gas pressure generated by the decomposition of the test material during the heating process and its change with time, nor can it automatically calculate the thermal decomposition degassing and kinetic parameters and give the storage life evaluation As a result, and the Brinell pressure gauge needs to be sealed with an open flame, there are problems such as large safety hazards. The present invention proposes a storage life evaluation test system and detection method for explosives.

Description
technical field [0001] The invention relates to an explosive storage life evaluation and detection technology, in particular to an explosive storage life evaluation testing system and a detection method. Background technique [0002] The Bruton glass membrane manometer method (referred to as the Brinell pressure method), was first applied to the study of the stability of explosives by the Soviet scholar Andreev in 1951, to measure the pressure of the gas products produced by thermal decomposition of explosives, and convert it to the standard state The volume of the lower gas, through the volume of the decomposed gas product and time relationship curve, study the thermal decomposition kinetic characteristics and decomposition mechanism of explosives, and then evaluate the storage life of explosives. [0003] The Brinell pressure gauge used in the Brinell pressure method is blown from molybdenum glass because its pressure sensor is shaped like a sickle. This method is also cal...
