Abstract:
1. A method for manufacturing aggregated resin particles, comprising: preparing a microreactor that includes, in a contained configuration: a first flow channel, a second flow channel, a confluent flow channel, to which the first flow channel and the second flow channel merge, and a third flow channel that merges into the confluent channel, wherein the first flow channel is disposed concentrically in an interior of the second flow channel; introducing a first fluid that contains resin particles dispersed therein into the first flow channel; introducing a second fluid into the second flow channel; feeding the first and second fluids so that a feed amount per unit time of the second fluid is greater than a feed amount per unit time of the first fluid, so as to form a laminar flow, in which the first fluid and the second fluid are merged, in the confluent flow channel; forming first aggregated resin particles by aggregating the resin particles while the first fluid and the second fluid are merged in laminar flow; introducing a third fluid into the third flow channel, wherein the third fluid contains inorganic or organic particles dispersed therein and a feed amount per unit time of the third fluid is greater than a feed amount per unit time of the second fluid, in which the third fluid and the merged first fluid and second fluid are merged, in the confluent flow channel; aggregating the inorganic or organic particles on outer sides of the first aggregated resin particles to form second aggregated resin particles while the third fluid and the merged first fluid and second fluid are merged; and heating the second aggregated resin particles,
