介绍了微孔塑料的几种制备方法,包括单体聚合法、(热引导)相分离法、压缩流体反溶剂沉淀法、间歇成型法、连续挤出法和注射成型法,分析并比较了各种制备方法的特点及应用,展望了微孔塑料光明的发展前景。
Punching plunger extrusion is a novel continuous extrusion molding technology, which provided higher processing capacity, better appearance and quality of the extrudate, compared with single-screw extrusion.
超高相对分子质量聚乙烯(PE-UHMW)管材连续挤出成型法有压制-烧结、柱塞推压、单螺杆挤出、双螺杆挤出和柱塞冲压挤出等几种,其中柱塞冲压挤出成型法是新开发的一种PE-UHMW管材连续挤出成型技术,该技术的突出优点表现在:能加工任意相对分子质量的PE-UHMW树脂,加工能力强;能实现连续挤出,生产效率不低于单螺杆挤出法,而制品的表面质量、力学性能(如耐磨性)则优于单螺杆挤出法;完全正位移输送机理,温度控制简单可靠(控温段只有三个),因此加工过程中的降解程度较小,能很好地保持原料固有的优良性能;主机结构简单,能耗低 (约为螺杆挤出法的30%-50%),生产线造价便宜。
The influencing factors and technical problems of continuous extrusion of microcellular plastic foams are explained.
