There are so many things that you have to be aware of when it comes to Rheology and one of which is the fact that it is the study of flow as well as deformation of materials under applied forces. More often than not, Rheology is measured using rheology measurement. In addition to that, we want you to know that the measurement of rheological properties is applicable to every single material, regardless of whether they are fluids (like dilute solutions of polymers and surfactants through concentrated protein formulations, or semi-solids like creams and pastes, or perhaps, solid or molten polymers such as asphalt. Moreover, you have to be aware of the fact that the properties of rheology are measured through bulk sample deformation using a micro-scale through a micropillary viscometer, an optical technique like a Microrheology, and also, a mechanical rheometer. There are so many commonly used formulations and materials out there that are exhibiting complex rheological properties, in which their viscosity as well as viscoelasticity vary in accordance to the external conditions applied like temperature, timescale, strain, and stress as well. There are other key factors that determine the properties of rheology like internal sample variations like protein concentration and stability, and formulation type of biopharmaceuticals.
Another essential thing about rheology that you must be aware of is that its properties impact every single stage of material use across a multitude of industries, may it be processing and product performance, or perhaps, development, stability, and formulation as well. With regards to matter concerning the type of rheometer viscosity test to be used in measuring these properties, they actually depend on related timescales and sheer rates, plus viscosity and sample size as well. Other than the things we mentioned here, there are still more that you have to be aware of like the fact that rheology and the effects that it has gone with us everywhere we go. Whenever there is a material being deformed, or flow, rheology will be there. There are other definitions of rheology such as the fact that it is pertained to as the science of the deformation and the flow behavior of substances. When the matter is deformed or flows, it only goes to show how there are mainly three factors to be considered and they are as follow: the internal structure, plus the external forces that acts on the substance as well as the known environmental conditions like temperature.
We have already stated above how the tool that is used in measuring the properties of rheology is called rheometer. For those of you out there who are curious to know about the properties of rheology that is being measured by a rheometer, well, they are the deflection angle of the measuring bob and torque.
All these and more are the things that you should know regarding rheology. Know more about rheology at https://en.wikipedia.org/wiki/Rheology.
