挤出机用高分子熔体过滤器的应用与发展

Application and Development of Polymer Melt Filter for Extruder

介绍了国内外挤出机用高分子熔体过滤器的种类、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，旋转园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其特点是更新滤网无需人工操作。由安吉化工塑机厂生产的循环滤块式不停机换网过滤器，安装了料压传感器，可避免漏换和错换，并可降熔体压３０ ％ 以上。

s The type,feature and application of the polymer melt filter for extruder made both at home and abroad are introduced.Double runner and double piston non stop screen change filter is used for the extrusion of PE and PP,while that of rotary disc type is used for the extrusion of chemical fiber.Automatic screen strip type is characterized by automatically screen change.The non stop screen change filter of cyclic filter block type made by Anji Chemical Eng & Plastics Machinery Factory is equiped with a compound pressure sensor,could avoid wrong change and decrease the melt pressure by 30%.
