The researchers observed a shear thinning
behavior in samples of both treatments.
For example, both samples show shear thinning
behavior, demonstrated by the complex viscosity decreasing as the shear rate or frequency increases.
7] showed on plastisol formulations the existence of a Newtonian plateau at very low shear rates, followed by a shear thinning
behavior and a second Newtonian plateau at intermediate shear rates (around 100 [s.
This is called shear thinning
, and the rate of deformation of the paint as it is sheared is called the shear rate (units are reciprocal seconds, [s.
The emulsions having 2- 8 wt % contents of Polyglycerol polyricinoleate (PGPR) indicated that an increase in shear rate increased the shear stress non-linearly and decreased the shear viscosity showing shear thinning
behavior up to some extent (Figs.
Innate resins exhibit high-melt strength for excellent bubble stability and greater shear thinning
to enable reduced extruder amperage and melt temperature.
A common example of how materials react to shear thinning
includes wall paint; paint shear thins during the brush or roller stroke for ease of flow and to fill imperfections, but quickly thickens to prevent runs and drips.
In this section, we examine the effect of fluid viscosity, including shear thinning
, on film uniformity under gap disturbances.
fluids are an important class of non-Newtonian fluids.
DUO-VIS has the unique ability to produce a fluid that is highly shear thinning
while developing a true gel structure.
Since all the values of n produced by the three fluid models are less than 1, then it is a shear thinning
fluid or so-called, pseudo plastic fluid.
Effects of shear thinning
for Gelatin reactive formulation is shown in fig.
