Extrusion processing and shaking were performed using the cleaning composition obtained in . Then, the amount of resin required until the extruded product was no longer colored was determined. The amount of resin required for root compaction using the same uncolored resin as the colored resin was determined under the same conditions.
以上の通り、本発明の洗浄剤は、各種成形機の色替え時

問題も解決された。Furthermore, the cleaning agent of the present invention is useful not only for changing colors, but also for general root tightening. For example, regardless of whether the molding machine is colored or uncolored, if you stop using the molding machine, the molding machine will not cool down rapidly, so the resin remaining in the molding machine will burn or carbonize due to the residual heat of the molding machine. However, by using the cleaning agent of the present invention when restarting the molding machine, these foreign materials can be easily removed. It was possible to remove the problem, and the above problems were also solved.
