注意事项Matters need attention

清洗料管

Purge compound

需使用PP或 PE清洗干净机台螺杆，且把机台射嘴彻底清除干净please make sure you that you have cleaned the machine screw with PP or PE, and put the machine nozzle thoroughly clean

着色

Coloring

请选择以PE或EVA为基材之色母，切勿使用以PVC为基材者。另外加工时请采用较高的螺杆转速和较高的背压，才能让着色剂达到较好的分散效果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）回收比率建议最多20%。

Consistent regrind usage of up to 20% is permissible
