PROCESS FOR PRODUCING COLORED SPHERICAL PARTICLES USING MICROCHANNELS AND MICROCHANNEL-TYPE PRODUCTION APPARATUS USED THEREFOR

摘要

The purpose of the present invention are two separate two-color display is very suitable for electrical and magnetic reversal on display colored region to monodisperse colored spherical particles each having, that is, character, picture, is to provide a two-color colored spherical particles used for the display such as video, it provides a novel method for manufacturing an apparatus for producing colored spherical particles and to. In the manufacturing method and apparatus for producing colored spherical polymer particles, comprising the dispersed color dye / pigment dispersed in the liquid medium containing a polymerizable resin component and a different color of the color tinted (6a, 6b) for moving the colored continuous phase having the first microchannel, spheroidizing phase 7 and using microchannels including a first microchannel is flowing. Different color tinted color of (6a, 6b) made of a colored continuous phase and the spheroidizing disperse phase 7 are each O / W (water-in-oil) or water / oil (oil-in-water) in the relationship. Tinted color forming a colored continuous phase (6a, 6b) is moved to the first microchannel 1, tinted colors (6a, 6b) a colored continuous phase comprising the second microchannel (2) flow through the spheroidizing disperse phase (7) at a predetermined flow rate (F2) (ml / hr) continuously or intermittently with the spherical screen of a two-color colored continuous phase discharged to the discharge and to cure the polymerizable resin component in the colored continuous mourning, the colored spherical polymer particles form.
