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).

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.
In many cases the degree of pseudoplasticity is a very good measure of the effectiveness of an RCA in a particular resin system.
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.
Among the research covered in this report: -- Polymerization, other interactions influence whey powder foaming -- Micellar extraction improves protein properties -- Novel dough formulation leads to soy-based bread -- Fortified phospholipids find nutraceutical and functional applications -- Pseudoplasticity, elasticity help stabilize citrus drink emulsions -- Engineered plants will have more antioxidants
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.
Baume is a composite number, influenced by the SG of the liquid and the suspended solids, the shape of the gauge, the liquid's viscosity and plasticity, the gelling characteristics, and other liquid characteristics including pseudoplasticity, rheopexy, thixotrophy, dilatency, Bingham plasticity and zeta potential.
Therefore, the high pseudoplasticity was observed for all the composites prepared in the study.
The former effect is known as pseudoplasticity and the latter as dilatancy.
