Processability of Microfibrillated Cellulose (MFC)

摘要

Two pipe flow regimes 1. Laminar shear-thinning flow 2. Fluidized flow (preferred) Centrifugal pump 3. Water-like behavior 4. Pumping limited by consistency Screw pump 5. Favorable when pumping high consistency MFC Tank mixing with conventional impeller 6. Fluidized cavity around the mixing impeller 7. Full mixing difficult at high consistency Data can be used in pipe dimensioning & pump selection.
