摘要
以亚利桑那(ISO12103-A2)试验粉尘为原料,通过研磨、筛分、沉降分离等技术,采用马尔文激光粒度仪对样品粒度分布进行测试表征,成功制备出累积粒度分布百分数达到50%、所对应的粒径(D_(50))在1.7~19.4μm粒径范围的9种宽粒径分布的试验粉尘。通过可重复性试验,证明研制的每种粒径范围的亚利桑那试验粉尘是可重复制备的。
Nine samples of test dust in the wide particle size range of 1.7〜19.4μm(D_(50))with cumulative particle size distribution percentages of up to 50%were prepared by applying grinding,sieving,sedimentation separation to the Arizona(ISO12103-A2)test dust.The Malvern laser particle size analyzer was used to characterize the particle size distribution of the samples.Repeatability tests showed that the developed Arizona test dust in each particle size range is reproducible.
