| Abstract: | A dew computing model of pressure distribution of ploymer in the channel of twin screw extruder is established. It is used to analyse the relation of operating parameters, such as rotation rate of screw, cold screw process , feed quantity and pressure distribution; and the effects of pressure distribution on the quality of extrusion material. By modifying the pressure distribution, the optimum operating parameters were determined. The computing results are compared with the experimental ones. |
