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5%. Consistent regrind usage of up to 5% is permissible. |
汽车部件中的高性能材料
国外TPV的最大用途是制造汽车配件,主要为EPDM/PP TPV和NBR/PP TPV。随着汽车向高性能(高速、安全、舒适、节能)、长寿命及轻量化发展,汽车部件特别是汽车密封系统、发动机系统等用TPV的呼声越来越高,以取代传统的热固性硫化胶。TPV在汽车密封系统的应用有挡风玻璃密封条、侧边反射镜的密封、遮阳篷的密封材料等;在汽车发动机系统的应用包括空气通风管、软管、防护罩、防震座垫、轴套等。其他汽车部件如刹车部件(皮碗、皮圈)和消音部件等。
