1、 1 塑料挤出机的应用研究 摘要 塑料挤出机在塑料挤出成型设备中,塑料挤出机通常称之为主机,而 与其配套的后续设备塑料挤出成型机则称为辅机。塑料挤出机经过100 多 年的发展,已由原来的单螺杆衍生出双螺杆、多螺杆,甚至无螺杆等多种 机型。塑料挤出机(主机)可以与管材、薄膜、捧材、单丝、扁丝、打包 带、挤网、板(片)材、异型材、造粒、电缆包覆等各种塑料成型辅机匹 配,组成各种塑料挤出成型生产线,生产各种塑料制品。因此,塑料挤出 成型机械无论现在或将来,都是塑料加工行业中得到广泛应用的机种之一。 关键词:关键词:塑料 挤出机 单螺杆挤出机 双螺杆挤出机 2 THE APPLICATION OF P
2、LASTIC EXTRUDERTHE APPLICATION OF PLASTIC EXTRUDER Abstract Plasti extruder in plastics extrusion molding equipment, plastic extruder, often called host, instead of supporting the follow-up equipments of plastic extrusion molding machine is called auxiliary engine. Plastic extruder after 100 years o
