Nanometer Powder Cleaning Purifying
During nanometer ultrafine powder production by wet chemical method, the slurry of ultrafine powder needs to be washed for removing impurity ion to improve product purity. For some nanometer powder with good dispersion, adopts washing methods such as traditional plate-frame high speed centrifugation etc., there have the defects such as powder handling not clear, filter liquor muddy, washing water consumption high volume, work strength high etc.
Ceramic membrane to be the new type separation elements, it can remove the impurity in slurry very well, to make the ultrafine ultrapure nanometer powder effectively.
Process Characteristics
