剪切和拉伸流动的机械加工,在变相过程中,实现的热分解的程度的原料。是必要的,以确保每一个部分的同样程度的处理,这样可避免某些部分不搅拌剪切力导致最终产生斑点和凝胶材料。通过TPE剪切和拉伸流动研究表明,热塑性弹性体具有相似的相对粘度,将有利于驱散。当一个临界值以上毛细血管的数量,只要简单的剪切流动,可以达到良好的分散。当然,实验证明,,使用拉伸流动,可以更好地实现分散。橡胶高弹性,高强度,高弹性,但也有注塑加工的特征,环保无毒安全,硬度范围广,优良的着色性,触感柔软,耐候性,耐疲劳性和耐温性优越的加工性能,不固化,可以循环使用,以降低成本,无论是二次注塑

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. |
