| 摘 要： | 讨论了矿物超细粉体的超细效应在一般粉体、异形粉体和功能粉体中的评价指标体系及常用的检测方法，指出粒度、纯度、表面性能和微粒力学性能是评价粉体超细效应的四大重要方面。异形矿物粉体在各种介质环境中的力学行为、形态系数和松解程度是其与一般粉体区分的根本标志，有待寻求更完善的方法来描述这类粉体的本质性状，并有利于改造、设计异形粉体的独特功能。

| Abstract: | This paper mainly studies the ultrafine effects of the mine r al ultrafine powders in the property assessment index system of ordinary powders , heteromorphic powders and functional powders. The common testing methods are a lso discussed. It has been shown that the granularity, purity, surface property and micro-particle mechanics are the four major aspects to evaluate the ultrafi ne effects of mineral powders. The mechanical behavior, shape index and unsticking percentage of heteromorphic powders and ordinary powders are essential criteria. More perf ect method for describing the essential behavior of these powders is requested s o that the special functions of the heteromorphic mineral powders can be created and designed. |
