摘　　要：利用一定目数微米木丝粉的孔穴,对PM2.5微尘颗粒进行过滤,并分析孔穴对PM2.5的过滤效果;同时利用电子显微镜,描述微米木丝粉表面特征以及微米木丝粉横断面的孔穴特点,实现了孔穴的识别,并分析了孔穴的过滤机理。结果表明,微米木丝粉孔穴对PM2.5微尘有很好的过滤效果。By using a number of cavity of micro wood fiber with powder,the dust PM2. 5 was filtered,and its effect was analyzed. By using electron microscope,the surface feature of micro wood fiber powder and cavity on the cross section were described,to realize the cavity recognition,to analyz mechanism of cavity filtering. The results showed that the micron wood fiber with powder cavities have a good effect for PM2. 5 dust.
