摘要
利用激光粒度分析仪测试了乳化炸药基质粒子大小与分布,研究了乳化炸药水相析晶温度、搅拌速度、乳化剂含量对粒子大小及分布的影响。结果表明:在一定条件下,水相析晶温度对分散相液滴大小与分布有较明显的影响;乳化搅拌速度存在一个临界值,本实验条件下此值为1230 r.m in-1,超过临界搅拌速度时,其分散相液滴大小与分布变化不显著,在临界搅拌速度以下,乳化搅拌速度影响十分显著;过分地增加乳化剂含量对分散相液滴大小与分布也没有明显作用。
The droplet size and distribution of dispersion phase for emulsion explosives matrix were tested by laser particle analyzer. The effect of the crystallizing temperature of water-phase ,the stirring speed, and the contents of emulsifying agent on the droplet size and distribution of emulsion explosives were studied. The results show that the effect of crystallizing temperature of water-phase on droplet size and distribution of dispersion phase is evident under certain conditions. There is a critical stirring speed of emulsion （ 1230 r · min^-1 ） below which the effect of stirring speed on the droplet size and distribution of dispersion phase is evident but is not obvious when the stirring speed of emulsion is over the critical value. The value is 1230 r · min^-1 under the experimental conditions. The additions of superabundant emulsifier agent to emulsions have no obvious effects on droplet size and distribution of dispersion phase.
