The characteristics of airborne dust in a soft paper production plant have been characterized by scanning and transmission electron microscopy. A combination of X-ray diffraction, electron diffraction and energy-dispersive X-ray flouresence spectroscopy (EDX) was used to determine the structure and composition of the different components. Size distribution determination and phase identification were carried out. Besides the cellulose fibres, fibres of kaolinite, wollastonite, talc and other silicates were also identified. Gravimetric analysis and fibre counting by optical phase contrast microscopy were used to determine total dust and fibre concentrations. Total dust exposure at the plant was generally below 3 mg m-3. The respirable fraction of the total dust concentrations varied from 15 to 70%. The inorganic dust was 36 +/- 15% of the total dust. The ratio of inorganic fibres to total fibre concentration at the plant varied between 10 and 15%.
通过扫描电子显微镜和透射电子显微镜对一家软纸生产厂的空气传播灰尘特性进行了表征。结合使用X射线衍射、电子衍射和能量色散X射线荧光光谱（EDX）来确定不同成分的结构和组成。进行了粒径分布测定和物相鉴定。除了纤维素纤维外，还鉴定出了高岭石、硅灰石、滑石和其他硅酸盐的纤维。采用重量分析和光学相差显微镜纤维计数法来测定总粉尘和纤维浓度。该厂的总粉尘暴露量一般低于3毫克/立方米。总粉尘浓度的可吸入部分在15%至70%之间变化。无机粉尘占总粉尘的36±15%。该厂无机纤维与总纤维浓度的比例在10%至15%之间变化。
