WANG Haoran, WANG Liye, YANG Chuanfang, et al. MODEL FOR SCALING-UP REVERSE MICELLE METHOD TO GET ULTRAFINE ZrO2 POWDER[J]. CIESC Journal, 2001, (12).DOI:
There are many methods for preparing ultrafine powder.For the reason of experimental condition and cost
it is difficult to scale-up.The reverse-micelle method overcomes these shortcomings
but because micromixing can not be obtained when oil is mixed with water
the result of scaling-up is unsatisfactory.In this paper
the spraying and rotating mixer is used to mix two phases quickly and uniformly
and a better product can be obtained.A mathematical model is used to deduce the result of mass transfer between two phases at different impeller speed and different phase ratio
then experimental result is used to test the exactness of the model.The model can be used for the research of scaling-up of this method.
