| 摘要 | The present invention provides a method of manufacturing coagulated grains from polymer latex and apparatus for exercising this method, said method being characterized in that a swirl of polymer latex is produced in tank, while holding it at a temperature lower than the softehing temperature of the polymer latex particles and while letting the same polymer latex as said polymer latex fall down into the aforementioned swirl liquid surface, a coagulant is added into said latex flowing-down liquid, thereby letting the coagulant disperse and scatter into the latex in the tank; thereafter, with said coagulant thus scattered as the seeds, coagulated layers are grown on their outer surfaces. According to this invention, nearly spherical coagulated grains with a uniform grain size may be obtained, while suppressing possible formation of massive coagulated matters. | ||||||
