摘要:
将多孔粒状硝酸铵（PGAN）加热到95～105 ℃，与加热到95～100 ℃的膨化剂溶液均匀混合，混合时间为3～5 min，膨化剂溶液的添加质量分数为3%-6%。混合完成后,将混合物进行真空脱水，真空度控制在-0.090～-0.075 MPa，脱水时间45～180 s，得到表面膨化的表面敏化改性PGAN。之后,根据所需的炸药品种混合液态油、黏性剂、添加剂，制备出不同品种的工业炸药，包括无梯粒状黏性炸药、改性粒状铵油炸药、高威力铵油炸药等。通过实验室制备及工业应用情况，全面地介绍了该PGAN的表面膨化技术及应用效果。
Abstract:
Porous granular ammonium nitrate (PGAN) was heated to 95-105 ℃. Then, it was mixed evenly with the expansion agent aqueous solution heated to 95-100 ℃ for 3-5 minutes. The added mass fraction of the expansion agent aqueous solution was 3%-6%. After mixing, the mixture was subjected to vacuum dehydration, with a vacuum degree controlled at -0.090 to -0.075 MPa and a dehydration time of 45-180 s, to obtain surface expanded surface sensitized modified PGAN. Afterwards, different types of industrial explosives were prepared by mixing liquid oil, viscous agents, and additives according to the required types of explosives, including granular viscous explosives without TNT, modified granular ammonium oil explosives, and high-power ammonium oil explosives. The laboratory preparation and industrial application were introduced. There was also a comprehensive introduction of the surface expansion technology and application of PGAN.
