注意事項(xiàng)Matters need attention

清洗料管

Purge compound

需使用PP或 PE清洗干凈機(jī)臺(tái)螺桿，且把機(jī)臺(tái)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(shí)請采用較高的螺桿轉(zhuǎn)速和較高的背壓，才能讓著色劑達(dá)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5%.

Consistent regrind usage of up to 5% is permissible.
