Physics and Procedures for Fluid Metering

Fluid nature has been called many things, such as rheological property, flow behavior, or the specific nature displayed by a slip. The practical implication is that the fluid being cast changes in viscosity 

Another rheological property often displayed by tape casting slips is thixotropy. Thixotropy describes the tendency of a slip to increase in viscosity over time under no shear. With no shear applied to a tape 

The combination of thixotropy and pseudoplasticity in a tape casting slip generally adds up to yield-pseudoplasticity. Yield-pseudo- 

Surface Tension and Wetting at the Slip/Carrier Interface 

Carrier speed consistency can be affected by a number of different factors. These include improper speed reference, drive chatter and motor variability (discussed in Section 4.1), and variable tension of the carrier film. Not all casting surfaces experience all of these variables. Variable tension is not usually an error source when casting on a metal belt or on a rigid substrate such as granite or glass. Polymer
