摘要:
液混式硝铵炸药生产过程中的真空度、硝铵溶液浓度、硝铵溶液温度及喷头间隙是影响其膨化效果的关键因素。文章结合生产工艺的优化，详细研究了这些因素对膨化效果的影响。研究结果表明，真空度低于0.086MPa，产品水分大，易结块；硝铵溶液浓度过高或过低都不利于膨化，一般控制在92.5%~93.0%最佳；硝铵溶液温度以120~128℃为宜，过低遇到附着面易产生结晶现象，过高膨化后物料发粘；喷头间隙以3.0~5.0mm为宜，过小膨化物料过于蓬松，过大导致筛上物增多。
Abstract:
The degree of vacuum in production process, concentration and temperature of ammonium nitrate solution and nozzle gap are key influencing factors for the expansion of liquidmixed ammonium nitrate explosives. Combined with optimization of explosive production process, the effects of these key factors on the puffed performance were thoroughly studied. The results show that a vacuum below 0.086MPa leads to increased water content and hardening in the explosives; the concentration of ammonium nitrate solution needs to be controlled in the range of 92.5% ~ 93.0% as a higher or lower concentration goes against puffing; the temperature of ammonium nitrate solution is determined as 120~128℃ since crystallization will happen at lower temperatures when the solution encounters the attachment surface while sticky materials will be generated at higher temperatures upon puffing; the favorable nozzle gap has a favorable value of 3.0~5.0 mm due to the appearance of fluffy extruded materials at smaller gap nozzle and increased oversized materials at larger gap nozzle.
