Types and Development of Melt Filter for Extruders

介绍了国内外挤出机用熔体过滤器的种类、特性和应用。双通道双柱塞不停机换网过滤器适合于PE、PP的挤出加工 ,旋转圆盘式不停机换网过滤器适合于化纤拉丝 ,网带式全自动过滤器更新滤网无需人工操作。安装料压传感器 ,可避免漏换和错换 ,并可降低熔体压力 30

s: Types, features and applications of melt filter for extruders worldwide are introduced. Double-runner and double-piston non-stop screen change filter are used for the extrusion of PE and PP, while the rotary disc type one is used for the extrusion of fibers. The striped screen change filter is characterized by automatically screen changing. The filter equiped with a melt pressure sensor could avoid wrong change and decrease the melt pressure by 30 %.
