| Abstract: | In order to provide theoretical basis and technical support for the design and actual processing of a co-rotating conical twin-screw,a study was done on the mixing performance of a co-rotating conical twin-screw extruder.The flow of rigid polyvinyl chloride(RPVC) was melted in a co-rotating conical twin-screw extruder.When the rotation speed was 25 r/min,the pressure difference between the entrance and exit of the extruder was zero,a co-rotating conical twin-screw extruder,a counter-rotating conical twin-sc... |
