往往压缩永久变形易与蠕变相混淆。然而,压缩永久变形是在某一恒定的应变条件下所发生变形的量,而蠕变则是在某一恒定应力条件下所发生变形的量。
变形是橡胶制品的重要性能指标之一。硫化橡胶压缩永久变形的大小,涉及到硫化橡胶的弹性与恢复。有些人往往简单地认为橡胶的弹性好,其恢复就快,永久变形就小。这种理解是不够的,弹性与恢复是相互关联的两种性质。但有时候,橡胶的本质没有发生根本的变化,永久变形的大小主要是受橡胶恢复能力的变化所支配。影响恢复能力的因素有分子之问的作用力(粘性)、网络结构的变化或破坏、分子问的位移等。当橡胶的变形是由于分子链的伸张引起的,它的恢复(或永久变形的大小)主要由橡胶的弹性所决定:如果橡胶的变形还伴有网络的破坏和分子链的相对流动,这部分可以说是不可恢复的,它是与弹性无关的。所以,凡是影响橡胶弹性与恢复的因素,都是影响硫化橡胶压缩永久变形的因素。

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. |
