Study Cards on cacas, shear, breakage
- Molecular scale --> self-assembly
- Larger structures --> deformation
It is the ability of a flowing liquid to form adjacent regions that have a shear-rate discontinuity at their interface.
CaCas --> fibrous structures
CaCas dispersion contained larger micelles, which makes the CaCas micelles more susceptible to hydrodynamic (shear) flow. In addition, due to the presence of calcium, it is expected that the attractive forces between the micelles are larger in the case of CaCas-dispersion.
CaCas --> shear-thickening at low shear rates, shear-thinning at high shear rates
NaCas --> shear-thinning (liquid-like) --> self-assembly under flow, not significantly altered by shear
- Higher grades + faster learning
- Don't study anything twice
- 100% sure, 100% understanding
