shear thinning

[′shir ‚thin·iŋ]
(fluid mechanics)
Viscosity reduction of non-Newtonian fluids (for example, polymers and their solutions, most slurries and suspensions, lube oils with viscosity-index improvers) that undergo viscosity reductions under conditions of shear stress (that is, viscometric flow).

Since we have already discussed Marten-sitic Transformations and Twinning, we would like to briefly discuss the Superplasticity or Pseudoplasticity phenomenon.
According to Chow and Ishak [25] the pseudoplasticity of nanocomposites can be as closely related to organoclay dispersion as the melt viscosity can be to polymer/clay interaction.
Furthermore, rheological data also contains the slope in log-log representation of viscosity vs shear rate and is the measure of paint pseudoplasticity.
The decrease in hardness at high temperatures (>1400[degrees]C) can probably be associated with the increased proportion of transformable tetragonal phase and associated pseudoplasticity [35].
On the other hand, mango pulp remarkably influences the pseudoplasticity of these mixtures.
04-40 [micro]m, and which as a dispersion in a plasticizer exhibits dilatancy; at least one finely divided PVC homopolymer, prepared by emulsion polymerization, having particle sizes of from 1-400 [micro]m, and which as a dispersion in a plasticizer exhibits pseudoplasticity; at least one plasticizer; at least one effect pigment and at least one additive, wherein the additive is comprised of an organic solvent, and the weight ratio is chosen so that the PVC plastisol exhibits pseudoplasticity.
The zero shear-rate viscosity and pseudoplasticity index decrease could be correlated with the plasticizer content by using an exponential function.
Another term for shear thinning is pseudoplasticity (ref.
These benefits come in addition to other typical properties of xanthan gum, such as stability, when exposed to the high salt levels and range of temperatures likely to be encountered at the seaside, compatibility with a wide range of ingredients, excellent suspension stability and pseudoplasticity characteristics.
This effective increase in polymer molecular weight, as a result, will cause the viscosity and pseudoplasticity of the ink to increase.
Results indicate that, in addition to viscosity, the pseudoplasticity and elasticity of emulsions play a significant role in stabilizing citrus drink emulsions.
