摘要
粉体颗粒粒度分布分形维能很好的表征颗粒群粒度分布。本文通过建立数字显微颗粒粒度分布分形维数值的数学模型,探讨粉体流动参数与颗粒粒度分布分形维数值间的关系,确认颗粒粒度分布分形维数值可以用于表征粉体流动性,形成了可靠和简洁的粉体流动性能测定新方法。
Powders＇ particle size distribution fractal dimension could denote size distribution well. Through established the mathematics model to calculate the size distribution fractal dimension which appropriate to the digital microtechnique, discussed the relationship of the powders＇ fluidity denotation parameters and powders＇ size distribution fractal value, affirmed that the size distribution fractal dimension could denote the fluidity of the powder, and formed a new method which could measure powders＇ fluidity compact and reliable.
