文章以硝酸铵溶液、膨胀珍珠岩、膨化剂为原料,通过向硝酸铵溶液中添加膨胀珍珠岩和控制硝酸铵膨化结晶制得一种新型膨化硝铵.并以92％膨化硝酸铵、4％复合燃料油和4％木粉混制出膨化硝铵炸药.检测结果表明,该炸药装药密度为0.90 g/cm3时,爆速为3805m/s,殉爆距离为8cm,猛度为14.7mm.经对比分析,该型炸药较传统膨化硝铵炸药装药密度和爆速分别提高了0.04 g/em3和331m/s,同时该炸药的制备方法简单,易于应用.%A novel expanded ammonium nitrate was prepared by the addition of expended perlite into ammonium nitrate solution and the control of ammonium nitration expanded crystallization.92％ new expanded ammonium nitrate,4％ compound fuel and 4％ coal powder were mixed in developing the new expanded ammonium nitrate explosive.Test results show that the new explosive has excellent explosion performance with charging density of 0.90 g/cm3,detonation velocity of 3805m/s,transmission distance of 8cm,and brisance of 14.7mm.As a result of comparison and analysis with the conventional counterparts,the new explosive features an increase of 0.04 g/cm3 in charging density and an increase of 331 m/s in detonation velocity.Furthermore,the preparation method of present explosive is simple and easy to use in industry.
