摘要
为进一步降低成本,优化乳化炸药配方,研究硝酸钠质量分数对乳化炸药性能的影响,分别使用含质量分数为0％、3％、6％、9％的硝酸钠水相材料制备乳化炸药试样,测试了其水相材料析晶点,测试不同储存时间炸药的爆速以及猛度.结果表明:随着硝酸钠质量分数的上升,水相材料的析晶点由83℃下降至76℃,乳化炸药的爆速和猛度先升高后降低.当硝酸钠质量分数为3％时,炸药的爆速和猛度达到最大,分别为5755m/s和16.5mm.
Abstract
In order to further reduce costs and optimize the formulation of emulsion explosives,the effect of sodium nitrate mass fraction on the performance of emulsion explosives was studied. Water phase materials containing 0％,3％,6％ and 9％ sodium nitrate were used to prepare emulsion explosives samples. The crystallization point of the water phase material was tested,and the detonation velocity and strength of explosives at different storage times were tested. The results show that as the mass fraction of sodium nitrate increases,the crystallization point of aqueous materials decreases from 83℃ to 76℃,and the detonation velocity and strength of emulsion explosives first increase and then decrease. When the mass fraction of sodium nitrate is 3％,the detonation velocity and intensity of the explosive reach their maximum values of 5755 m/s and 16.5 mm,respectively.
