Chapter 20. Scale-up Rules of Extruder |
|
[Simulation Analysis for Polymer Processing by PC (11), Japan Plastics, Vol.50, No.10, P.105 (1999)]
At the last chapter of this series, scale-up rules of extruder are taken up. Scale up rule cannot bring out equivalent answer by simulation, but is used frequently as a simple method of guessing approximate answer from the data of small-scale equipment. Many scale-up rules of extruder have long been published. Most of all rules focus on the behavior of melt, and the basic premise of the scale up is getting same quality (mixing degree) and temperature of the melt. This chapter presents miscellaneous scale-up rules [18], [19], [20], [21], including a rule claiming for getting same quality of plasticating extruder [22], and their calculation examples.
