无机盐对硝酸铵溶解温度和膨化硝铵炸药爆炸性能的影响
Influence of Inorganic Salts on the Dissolution Temperature of Ammonium Nitrate and the Explosive Performance of Expanded Ammonium Nitrate Explosives
摘要
Abstract
In order to explore the influence of inorganic salts on the dissolution temperature of ammonium nitrate and the explosive performance of expanded ammonium nitrate explosives,the inorganic salts of 2％,4％and 6％of NaCl,KCl,NaNO3 and KNO3 respectively were used to replace the ammonium nitrate content in the expanded ammonium nitrate explosives,and the explosion performance(including the detonation velocity,the fierceness,and the work ability were measured).The results show that when the mass fraction of inorganic salt is 2％,the dissolution temperature is 8 to 12 ℃ lower than that of the traditional puffed ammonium nitrate formula explosives;the expanded ammonium nitrate explosives with NaNO3 and KNO3 is 120-150 m/s higher than the traditional formula,and NaCl and KCl are reduced by 150-850 m/s;lead column compression of NaNO3 and KNO3 increased by 0.62-1.90 mm,and NaCl and KCl decreased by 0.06-2.55 mm;the peak overpressure of NaNO3 and KCl increased by 0.02-0.78 kPa,and NaCl and KNO3 inorganic salts decreased by 5.02-19.57 kPa.For every 2％increase in the mass fraction of inorganic salt substitution,the dissolution temperature decreases by 7 to 10 ℃;the detonation velocity decreases by 100 to 300 m/s;lead column compression decreases by 0.08 to 0.73 mm;and the peak overpressure decrease by 1.77 to 13.5 kPa.In practice,a small quantity of NaNO3 can be added to the expanded ammonium nitrate explosives,which is not only conducive to reducing the dissolution temperature of ammonium nitrate,but also enhances the explosive performance of explosives.关键词
