国内外超细粉体液固分离技术的发展概况

过滤是固液分离的组成部分。过滤的目的一般是从悬浮液中分离出固体和液体。膜技术作为一种新兴的过滤技术具有其代表意义。它可以截留小到几个纳米的细微颗粒,多用于制造纯净水或化学工业上的某些分子提纯浓缩。

The Developing Situation of Domestic and Foreign Ultrafine Powder's Liquid-solid Separation Techniques

The filtering is the component of the liquid-solid separation.The target of the filtering generally is to separate the liquid and solid from the suspending liquid.The membrane technique,being as a kind of new-developed filtering technique,possesses the representative significance.The membrane technique,which can catch the minute particles with the diameter of less than several nanometers,is mostly used in manufacturing the pure water or some molecular purification and concentration in the chemical industry.
