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 are 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
减少tpe材料气味的小细节
TPE之所以会有气味,主要是高温共混或加工组分小分子挥发所致。建议如下:
1.TPE配混体系,尽量选择VOC挥发小的操作油及加工助剂。操作油应选择氢化度高的品种。
2.TPE共混料。充分冷却后打包,料粒的气味会小些。
3.TPE制品加工。高温注塑成型,气味难免,油的含量越大,气味越大。但加工成品冷却后,制品气味会慢慢变淡。
