摘要
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.关键词
