Webthix·ot·ro·py. ( thik-sot'rŏ-pē ), 1. The property of certain gels of becoming less viscous when shaken or subjected to shearing forces and returning to the original viscosity on standing (for example, synovial fluid, ferrous hydroxide gel). 2. WebJul 19, 2024 · Thixotropic yield stress fluids are used in a multitude of industries, including foods, cosmetics, pharmaceuticals, and paints. Thixotropy refers to the time-dependency of complex fluids, which means the material properties depend not only on the applied shear rate or shear stress but also on the material deformation history [ 20–24 20.
Thixotropy is a time-dependent shear thinning property. Certain gels or fluids that are thick or viscous under static conditions will flow (become thinner, less viscous) over time when shaken, agitated, shear-stressed, or otherwise stressed (time-dependent viscosity). They then take a fixed time to return to a more viscous … See more Some clays are thixotropic, with their behavior of great importance in structural and geotechnical engineering. Landslides, such as those common in the cliffs around Lyme Regis, Dorset and in the Aberfan spoil tip disaster See more Many kinds of paints and inks—e.g., plastisols used in silkscreen textile printing—exhibit thixotropic qualities. In many cases it is desirable for the fluid to flow sufficiently to form a uniform layer, then to resist further flow, thereby preventing sagging on a vertical … See more • Bingham plastic • Calcium Sulfate • Dilatant • Kaye effect See more The word comes from Ancient Greek θίξις thixis 'touch' (from thinganein 'to touch') and -tropy, -tropous, from Ancient Greek -τρόπος -tropos 'of turning', from τρόπος tropos 'a turn', from τρέπειν trepein, 'to turn'.

WebAug 22, 2024 · Thixotropy is a reversible sol phenomenon that occurs under the action of mechanical forces such as vibration and compression. Plastic viscosity, yield stress, and thixotropy reflected the micro-rheology of the suspension and indirectly reflected the influence of the internal structure on the flowability.
WebJun 10, 2024 · THIXOTROPY: UNDERLYING CONCEPT AND APPLICATION TO MUSCLE Most fluids produce a viscous resistance to movement; the force depends on the rate of deformation. In some of these fluids, the viscosity decreases when they are stirred or made to flow rapidly, a phenomenon known as shear thinning.
