Investigation of the water content effect on primer mixtures self-ignition parameter

The thermal decomposition properties of primer mixture 1 with different water content can be investigated using a series of thermal analysis equipment and by its technique. By the DSC analysis in this work, although the major exothermic peak of the primer mixture 1 with different water content, at the temperature range from 250 to 350°C were gradual disappeared when increasing the water content of primer mixture 1, but this result could not indicate that the detonating ability of wetted primer mixture 1 was lost. And by TG analysis, wetted primer mixture 1 was still found possessing detonation properties under a higher heating rate condition. Although wetted primer mixture shows hard detonating character but we still need very carefully when executing a disposal mission.
