Title:
METHOD FOR MANUFACTURING GROUP OF FINE PARTICLES AND GROUP OF FINE PARTICLES MANUFACTURED BY THE SAME METHOD
Document Type and Number:
Japanese Patent JP2020055257
Kind Code:
A
Abstract:
To provide a method for manufacturing a group of fine particles that can be effectively used for a wide range of applications, and which has several characteristics such as less manufacturing cost, suitable inclusion of carbon fiber resin, and the fact that the fine particles can be obtained by controlling the ratio of carbon fiber to epoxy resin.SOLUTION: The invention is related to a method for manufacturing a group of fine particles, wherein the carbon fiber-containing epoxy resin body is crushed and the carbon fiber is coated with epoxy resin around the carbon fiber, and the epoxy resin content (CER[mass%]) expressed in the following formula has a specific value, and wherein the CER is reduced (increased) by increasing (decreasing) the rotational speed or circumferential speed of the impeller 14 and/or widening (narrowing) the impeller spacing D of the two impellers 14 when grinding is performed by using an airflow grinder 11. CER[mass%]=100×[mass of epoxy resin in particulate group (g)/[mass of particulate group (g)]SELECTED DRAWING: Figure 2
