摘要：以刨花板和纤维板生产中的9种木质散碎物料为研究对象,采用Carr指数的研究方法,测定了C a r r指数的四项评价指标(堆积角、压缩率、抹刀角、均匀度),通过四项指标分数的高低,比较了9种木质散碎物料的流动性。结果表明,通过Carr指数法的得分高低可以反映木质散碎物料的流动性难易,分数越高,越易流动;9种木质散碎物料的流动性可分为易于流动(砂光木粉)、一般流动(稻杆刨花板表层等)和不易流动(木制品工艺刨花);利用HR(粉体的Hausner比值)值评定散碎物料的团聚度,指出可以用此方法比较木质物料之间的搭桥倾向。
9 kinds of different wooden bulk materials produced in the particleboard and fiberboard were measured by the method of Carr-evaluation in this study. The flow characterization of wooden bulk materials was evaluated by the method of Carr indexes.The results showed that the Carr-evaluation can be used to evaluate the variation of flowing characterization of wooden bulk materials, the more score it had, the better flow characterization it had.;9 kinds of different wooden bulk materials were divided into three categories, they are easy flow（such as sanding wood powder）, general flow（such as stalks used in the straw particleboard surface） and difficult flow（such as craft wood shavings）.Otherwise, HR was used to value the reunion of materials to compare the bridge tendency of wooden bulk materials.
