无机添加剂对硝酸铵拒爆性的影响研究

The effects of inorganic additives on the misfire properties of ammonium nitrate were investigated. With the incorporation of inorganic additives (3% GXJ1 and 10% GXJ2) in ammonium nitrate, the misfire properties can be improved significantly. The explosive mixture of the modified granular ammonium nitrate and diesel oil according to the industrial formula can not be detonated by No. 8 detonator. Moreover, as a safe compound fertilizer, the modified ammonium nitrate behaved well for the agricultural use with high granular strength and resistance to agglomeration and moisture absorption. The modified ammonium nitrate was then characterized with SEM and XRD to investigate the mechanism of the misfire improvement by the inorganic additives.
