含退役火药新型高爆速震源药柱配方和工艺的研究

Formulation and Process of New High Detonation Velocity Featured Seismic Charge Containing Waste Propellants

根据退役发射药品种、规格型号、性质不同,解决发射药粉碎和推进剂切割加工技术的问题。含退役火药乳化炸药以60mm内装药,配置150g传爆药柱,产品密度在1.40～1.43 g/cm3之间,爆速可达到6300 m/s,爆炸连续性达12kg。通过实验数据,分析了发射药粉粒度、密度、装药直径对爆速的影响。在上述配方基础上压入推进剂,可使密度提高到1.47 g/cm3,爆速达到7300 m/s以上,同时储存期可达到2年以上,性能优于铵梯高爆速震源药柱,成本低廉,无污染。为退役火药的综合利用开辟新途径。

New technology was developed in propellant powder smash process and propellants explosive cutting process for the waste propellants with different variety, specification, type and property. A load of 060mm emulsion explo- sive containing waste propellants with 150g booster pellet makes up the product having a density between 1.40 - 1.43 g/cm3 , a detonation velocity of 6300 m/s, and a explosive continuity of 12kg. Based on experimental data, the influence of propellants on the detonation velocity was analyzed in view of its particle size, density and charge diameter. When the pro- pellant explosive was introduced into above basal formulation, it shows the increased density up to 1.47 g/cm3 , detonation velocity over 7300 m/s, and product storage period up to 2 years, better properties than ammonium nitrate seismic charge of high velocity detonation in addition to the advantages of lower cost and non pollution. This provides a new approach for the waste propellants comprehensive utilization.
