| 摘 要： | 利用激光粒度仪和光效应测试仪测定铝粉的粒径和照明剂的发光强度。研究不同形状和粒径的普通铝粉,以及用化学法细化制备的超细粉对Ba(NO3)2+Al照明剂发光强度的影响。结果表明:照明剂的发光强度随铝粉粒径的减小而增大,非球状铝粉的发光强度大于球状铝粉的发光强度。粒径在小于2μm时发光强度的变化率陡增,粒径在0.6～2.13μm区间发光强度变化率是2.13～4.24μm区间发光强度变化率的4.37倍,表明铝粉超细化至亚微米后可以大幅度提高烟火药剂的发光强度.

| Abstract: | The particle diameter and luminous intensity of aluminum powder were measured by laser analyzer and photo-effect tester.The luminous intensity of Ba(NO3)2+Al illuminant was studied for different shape and diameter of aluminum powder as well as ultra-fine powder prepared by chemical method.The results show that the luminous intensity increases with particle size reduced,and luminous intensity of non-spherical aluminum is more than that of spherical aluminum.The change rate of luminous intensity increases rap... |
