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 |

时间
完成一次注射过程所需的时间称为成型周期。成型周期包括充模时间、保压时间、冷却时间和其他时间(开模、脱模、闭模等),直接影响劳动生产率和设备利用率。TPU的成型周期通常决定于硬度、制件厚度和构型,TPU硬度高周期短,塑件厚周期长,塑件构型复杂周期长,成型周期还与模具温度有关。TPU成型周期一般在20~60s之间。
注射速度
注射速度主要决定于TPU制品的构型。端面厚的制品需要较低的注射速度,端面薄则注射速度较快。
螺杆转速
加工TPU制品通常需要低剪切速率,因而以较低的螺杆转速为宜。TPU的螺杆转速一般为20~80r/min,则优选20~40r/min。
