In Twin-Screw Compounding, Distinguish Between 'Disease' and 'Illness'

摘要

The concept of troubleshooting in compounding can be defined in terms of a problem (or problems) with compound quality or as a problem with the compounding process. The latter may or may not be seen by the customer, as these troubles result in lost productivity for the compounder: strand drops, vent port fouling, etc. In either case, the strategy to identify an assignable cause (and cure) is to first determine if the problem is chronic or transient.
