Abstract

PURPOSE:To enable to obtain highly uniform melt by installing a dynamic mixer provided with the mixing unit composed of multiholed plates, rotating blades and the driving shaft of rotating blades. CONSTITUTION:Molten polymer sent forcibly by the screw of an extruder arrives at first at a strainer plate 1, and solid particles larger than the hole diameter of the small hole part are caught here. Polymer passing through the strainer plate 1 enters into a space 18 and millled positively by rotating blades 7. Then, polymer arriving at a multiholed plate is forced into holes smaller 20 than small holes of the strainer plate 1, and in this time solid and semisolid substances which are difficult to pass through the smaller hole are ground by strong shearing force of the rotating blade 7. Further, as polymer proceeds successively to second step, third step etc., the same operations are repeated. And at the same time the diameter a of the small hole of plural multiholed plates 2-5 becomes successively smaller, than the particles passing through these plates are ground and become finer.
