Optimization of Transformable Multiple Impeller (AM Impeller) for Highly Viscous Fluids

Journal of Advanced Manufacturing and Processing, EarlyView.
ABSTRACT Mixing performance in a laminar flow with a mixing Reynolds number less than 10 is greatly affected by the geometry of the impeller blades, and how to generate axial flow is important. The authors developed a new AM impeller with a low production cost by combining simple pitched paddle impellers in multiple stages.

Enhancing Flexibility and Adhesion of PVDF Coatings on PVC Textiles via PVDF/PMMA/Plasticizer Blends

Journal of Applied Polymer Science, EarlyView.
ABSTRACT This study investigated improving the flexibility and adhesion of polyvinylidene fluoride (PVDF) coatings on polyvinyl chloride (PVC) textiles by blending PVDF with polymethyl methacrylate (PMMA) and adding plasticizers. Because PVDF is inherently stiff, blends were prepared with 10 wt%, 30 wt%, and 50 wt% PMMA.
