Rheology Knowledge

Dynamic viscosity : η (eta) It is defined by the NEWTON equation: and quantify measurement of internal friction of fluid. His determination needs to apply to the fluid a Shear rate (D), and to measure the resistant Shear stress (τ) to this rotation. Shear rate : D (shear rate) is the shearing which subjected by the product in the application. It is known for measurement geometries with small gap. It is not the speed of rotation of the bob (in rpm !). Either a sheared fluid, by a laminar move (dV), between two parallel plates with a surface (S) and separate by a distance dx. Shear stress : τ (Tau) There is the shearing force (F), with which...

Glossary

Adhesiveness: is the sticky power of a product. It is measured during a tension phase in texture analysis, by the negative force measured and also by the surface under the base line. ASTM: American Society of Testing Materials. American organisation in charge of creating ASTM standards. BINGHAM: model of rheological flow behaviour, characteristic of plastic products (shear-thinning with yield stress). CASSON: model of rheological flow behaviour, allows the precise determination of non-linear plastic product’s yield stress. Centipoise (cP): measuring unit of dynamic viscosity in the MKSA system; equivalent to mPa·s in the SI system....
