粒径≤2μm的超细粉体颗粒分散方式的探讨

Ultra-fine particles have a tendency to reunite spontaneously with the increase of their particle size. To improve particle’s dispersion is regarded as the base of the realization of ultra-fine particles’ fractionation, and the key techniques of their preternatural physical and chemical peculiarity. The mechanisms of agglomeration and dispersion of ultra-fine particles are proposed in this paper, all kinds of dispersion methods and their application range in and out are compared then. The results showed that: Ultra-fine particles with a size no more than 2μm should be dispersed in liquid with physical-chemical methods.
