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 |
