Study about Effect of Particle Size and Gradation of Modified AN on the Sensitivity of Modified AN

摘要：

The mechanical sensitivities of modified AN with different particle sizes were tested by referring to the criterion GJB772A-97 and the detonator sensitivities of modified AN with different gradation is discussed in this paper. The experimental results show that the particle sizes of modified AN have an obvious effect on the mechanical sensitivity. The mechanical sensitivity increases with the increment of particle size of modified An in a range, however, it will go down if the particle size increased is beyond this range. Therefore, mechanical sensitivity can be decreased and the detonator sensitivity can be improved by changing the gradation of modified AN.
