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

流动痕迹

　　在成型品表面出现光泽不同的条纹现象。一般来讲，在树脂的注射成型中有：

　　（1）间隔窄的记录条纹状；

　　（2）在成型品表面上下出现同位相的比较宽的间隔条纹状；

　　（3）在成型品表面上下出现异位相的比较窄的间隔条纹状三种类型。

　　解决方法:可以通过这些方法来解决，如添加纯单体树脂、提高注射速度、模具温度、加大注胶口、提高树脂温度和注射速率、提高成型温度、模具温度或降低注射速度等。通过提高注射速度和模具温度都是有效的。
