METHOD FOR PRODUCING FINE POWDER

摘要

The objective of the present invention is to provide a method for producing a fine polymer powder with which it is possible to easily produce a scaly powder that is thin and has excellent thickness uniformity. This objective is achieved by: a fine powder production method comprising a step for alternately laminating two types of resins (resin A and resin B) and preparing a multi-layer laminate including at least 16 layers, a step for reducing the laminate into a fine powder by pulverization, and a (peeling) step for dividing the interface between the laminated layers; and particularly a fine powder production method in which the pulverization step and the division step are integrated.
