(续上期)3挤出以下是几种常见的与挤出工艺有关的问题。3.1挤出膨胀率在挤出过程中控制挤出膨胀率是重要的,这是为了使挤出半成品保持良好的尺寸稳定性。挤出膨胀率的大小主要取决于应用的剪切率。如果在挤出过程中施加于胶料的剪切率较高,那么最终的挤出膨胀率通常就会比较高?
(Continued) 3 Extrusion Below are some of the common problems associated with extrusion processes. 3.1 Extrusion Expansion Rate It is important to control the extrusion expansion rate during extrusion in order to maintain good dimensional stability of the extruded semifinished product. The size of the extrusion expansion depends mainly on the shear rate applied. If the shear rate applied to the compound during extrusion is high, then the final extrusion expansion will usually be higher?
