摘要： A functional particle is manufactured by a method including an aggregating step, a depressurizing step, and a cooling step. In the aggregating step, the functional particle is obtained by flowing a mixed slurry containing a core particle and a shell particle through a coiled pipeline while heating the mixed slurry to a glass transition temperature or higher of the core particle, to deposit the shell particles on the surface of the core particle. In the depressurizing step, the grain size of the functional particle is controlled and the coarse particle is pulverized to make the grain size of the functional particles uniform. In the cooling step, re-aggregation of the functional particles with unified grain size is prevented.

摘要： There is provided a method of manufacturing coalesced resin particles for obtaining coalesced resin particles by coalescing aggregated resin particles in a grain boundary-free state in a short period of time while keeping a grain size distribution within a narrow range. In a coalescence process, a slurry of aggregated resin particles is flowed through an inside of a pipe under predetermined heating and pressurizing conditions. In a before-cooling decompression process, a slurry of coalesced resin particles flowing through the inside of the pipe in a heat and pressure-applied state is subjected to pressure reduction before it is cooled down to a predetermined temperature in a cooling process. Then, in a decompression process, a coalesced resin particle slurry that has been cooled in the cooling process while being flowed through the inside of the pipe is decompressed to an atmospheric pressure.
