摘要:
通过起爆药在有机玻璃管壳中压药上浮试验和流散性测定，发现球形糊精氮化铅中粒径＜45 μm颗粒的含量增多，使药剂装药性能下降、流散性变差，压药容易上浮；频繁压爆、毫秒延期电雷管瞬爆是压药上浮所致。提出两项质量控制指标：药剂堆积密度≥2.00 g/cm3;粒径＜45 μm颗粒的质量分数≤20%。工艺参数：3%(质量分数)氮化钠溶液加入8%(质量分数)硝酸铅溶液，水药质量比30：1，工业酸性糊精质量分数（外加）5%，氮化钠溶液碱度0.080%，化合温度60℃。保持一定的加料速度和搅拌强度，能稳定生产出满足雷管装配需求的起爆药。
Abstract:
Through the chargepressing floating test and fluxion property determination of initiating charge in organic glass shell, it is found that reduction of loading performance, bad fluxion property and easy floating of chargepressing would occur with the increasing of mass fraction of particles with grain size less than 45μm in spherical dextrin lead azide. It is also found that chargepressing floating will be caused by frequently burst pressure and instantaneousexplosion of MS delay electric detonator. Two quantity control indexes were proposed including bulk density≥ 2.00 g/cm3, and mass fraction of particles with grain size less than 45 μm ≤20%. Preparation process is as follows: 3% (mass fraction) sodium nitrite solution is added into 8% (mass fraction) lead nitrate solution, the mass ratio of water and charge is 30：1, additional amount of industry acidity dextrin is 5% (mass fraction) , alkalinity of sodium nitride solution is 0.080%, and the certain feeding speed and stirring intensity are maintained at the temperature of 60℃. The manufactured initiating charge can meet the requirements of detonator assembly.
