Title:
A manufacturing method of surface modification fine powder
Document Type and Number:
Japanese Patent JP6235971
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a surface-modified fine powder capable of sufficiently reducing the volatile components remaining on a powder surface after surface treatment at a low temperature in a short period of time.SOLUTION: There is provided a method for producing a surface-modified fine powder which comprises: a step of subjecting a surface-modified fine powder to mixing treatment with a flowing gas; and a step of subjecting the surface-modified fine powder and the flowing gas to solid-gas separation, wherein the solid-gas ratio (the surface-modified fine powder/the flowing gas) of the surface-modified fine powder during the mixing treatment and the flowing gas is controlled in the range of 0.1 to 10 kg/m.SELECTED DRAWING: Figure 1
