WET USE CHOPPED STRAND GLASS AS REINFORCEMENT IN EXTRUDED PRODUCTS. |
摘要 |
<p>A method for incorporating wet use chopped strand glass (WUCS) in a screw extrusion process is provided. A polymeric resin is added to an extruder (100) in a polymer feed zone (106) and conveyed to a first compression zone (113) where the resin is at least partially melted. The molten resin is conveyed to a high volume zone (107) where WUCS fibers are added. In the high volume zone, the flights of the screw may have a greater pitch to facilitate the introduction of the WUCS into the extruder. The molten resin/fiber mixture is conveyed to a second compression zone (112) where the resin and fibers are intimately compounded. Next, the molten resin/fiber mass is conveyed to a low pressure zone (115) where moisture evaporated from the fibers is released through an opening (109). The resin/fiber mixture is then conveyed through a compression/die feed zone (116) to further compound and mix the resin and fibers.</p> |
