| Abstract: | This paper introduced the principle and equipment of continuous extrusion moulding of microcellular plastics as well as the advantage of using supercritical CO2 fluid in the preparation of microcellular plastics.The relative merits of two kinds of nucleation devices,i.e.quick pressure-relief nozzle and gear pump adopted in the continuous extruder were expounded.The development status of continuous extrusion processing technology of microcellular plastics with supercritical CO2 fluid as foaming agent was reviewed.The research direction of microcellular foams in the future was envisaged. |
