Abstract :
This paper study a dual-screw profile extruder with erose taper used in PVC-U molding processing, presents a temperature computer control system in which a combined-control strategy of on-off control, fuzzy-control and integral-control were adaptive elected. Lonworks were adopted as system fieldbus to construct a net to regulate the extruderpsilas sub-areas temperature in line. App effect shows that the temperature control precision is plusmn1% and the method of multi-subarea control in line with Lonworks filedbus has better effect than those sub-areas self-governed control, and can prevent PVC-U decompounding in the processing effectively, so the character of PVC-U manufacture could be improved.
