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 are needed for better colorant dispersion |
回收 Recycling | 二次料（水口料）回收比率建議最多10%。 Consistent regrind usage of up to 10% is permissible |
