Define thixotropy
WebMar 1, 2009 · The rheological manifestation of flow-induced structural changes is a variable viscosity. If the changes are reversible and time dependent, the effect is called thixotropy. The basic elements of this concept are reviewed here, including its definition and the relation with nonlinear viscoelasticity. WebThixotropy definition: The property exhibited by certain gels of becoming fluid when stirred or shaken and returning to the semisolid state upon standing.

Webthixotropy: [noun] the property of various gels of becoming fluid when disturbed (as by shaking). WebIf a remoulded soil is left alone undisturbed at the same water content for some time, it may regain part of its lost strength. This gain of strength in the soil with the passage of time …
WebThixotropy is the term given to the reduction in resistance of sand with increased rate of shear, as opposed to dilatancy (where increasing shear force causes increased … WebIn continuum mechanics, rheopecty or rheopexy is the rare property of some non-Newtonian fluids to show a time-dependent increase in viscosity ( time-dependent viscosity ); the longer the fluid undergoes shearing force, the higher its viscosity. [1] Rheopectic fluids, such as some lubricants, thicken or solidify when shaken.
WebA thixotropic fluid is one that takes a fixed time to return to its equilibrium viscosity when subjected to abrupt changes in shear rate. In other words, the liquid becomes less viscous (thinner or flows more easily) when shaken, stirred, agitated or otherwise stressed. The fluid then recovers its original viscosity in a fixed time once the ... WebMar 9, 2024 · Thixotropy is a way of describing a gel-like substance acting as a solid when a fast force is applied to it, while also acting as a liquid when a slow force is applied. This means that if you hit the surface of a thixotropic substance with, say, a hammer; it will bounce off the surface. But, if you lay that hammer down on the surface, it will ...
Webthixotropic. ( ˌθɪksəˈtrɒpɪk) adj. (Chemistry) (of fluids and gels) having a viscosity that decreases when a stress is applied, as when stirred: thixotropic paints. [C20: from Greek …
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 state. Some non-Newtonian pseudoplastic fluids show a time-dependent chang… city of carrabelle utilitiesWebPublisher Summary. This chapter presents the measurement and occurrence of thixotropy and dilatancy. The concept of thixotropy arose in the study of certain colloidal dispersions. These were capable of stable existence as solid materials with a low modulus of elasticity when under a low shearing stress such as a few inches of gravitational head. don bartley masteringWebApr 22, 2024 · Thixotropy is a property of some products which change their viscosity and become more fluid when subject to constant shear force, e.g., in the mixing stage.
