摘要
笔者采用斜槽法对混料工艺的RDX与筒壁的摩擦情况进行模拟,对斜槽进行了改进,并对铝粉的静电起电性能进行了独立的测试。实验表明,在环境温、湿度相同时,RDX经摩擦带负电荷(-4.5^-13.5 nC/g),铝粉带正电荷(0.4~4.4 nC/g);静电积累量与药品的质量呈线性增加,换算成千克每纳库,呈递减关系;让RDX通过不同角度的两种斜槽,其静电积累值约为-4.5^-13.5 nC/g(钢板)、-4.9^-11.8 nC/g(铝合金板);斜槽角度的增大会使药品的静电积累值变大,在角度为60°~70°之间,RDX的静电积累出现最大值。
The friction between RDX and cylinder wall is simulated with the slope method and the chute is improved in this paper. And the frictional static electricity performance of aluminum powder is tested independently. The result indicates that in the identical temperature and humidity, RDX is negatively charged （4.5-13.5 nC/g）, aluminum is positively charged（0.4- 4.4 nC/g）. The quantity of static electricity and the quality of the medicine increased linearly. Making RDX through two kinds of funnel in different angles, the electrostatic accumulation is about 4.5-13.5 nC/g（steel plate）, 4.9-11.8 nC/g（aluminum alloy）. Skewing angle can make the increase of electrostatic accumulation, it is 60°-70°, and RDX electrostatic accumulation is the maximum.
