注意事項Matters need attention

清洗料管

Purge compound

需使用PP或 PE清洗干凈機臺螺桿，且把機臺射嘴徹底清除干凈please make sure you that you have cleaned the machine screw with PP or PE, and put the machine nozzle thoroughly clean

著色

Coloring

請選擇以PE或EVA為基材之色母，切勿使用以PVC為基材者。另外加工時請采用較高的螺桿轉(zhuǎn)速和較高的背壓，才能讓著色劑達到較好的分散效果Please select color master batch on PE or EVA material with the exception of PVC.Higher screw speed and backpressure and needed for better colorant dispersion

回收

Recycling

二次料（水口料）回收比率建議最多20%。

Consistent regrind usage of up to 20% is permissible
