Research on single screw extrusion technology for secondary recovery of PP non-woven fabric strip
The problems and solutions of feeding continuity and plasticizing process in the second-ary plasticizing process of PP non-woven fabric strips by single screw extrusion were described,it pointed out that parameter design of screw feeding section,compression section,metering section,and cooling of outer section of thread barrel were the key factors to realize uninterrupted feeding and stable plasticizing extrusion of PP non-woven fabric strip.The key problems were solved by in-creasing the friction of the feeding section,adjusting the compression ratio and length ratio of the compression section,adjusting the clearance and barrier of the metering section,and controlling the temperature of the external section.
