Learn Everything There Is For You To Know When It Comes To Rheology


28 Oct

When we say Rheology, we are actually referring to the study of deformation and flow of materials under applied forces. Most of the time, this study is measured using a Rheometer in a routinely manner. 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. And also, it has been said as well that rheological properties are measured from bulk sample deformation through the use of a mechanical rheometer, to a micro-scale using a micropillary viscometer, to an optical technique like Microrheology. These days, there is a rise in the number of commonly used formulations and materials that exhibit complicated and complex rheological properties, by which the viscoelasticity and viscosity vary depending on various external conditions applied like timescale, stress, temperature, and also strain. You have to be aware of the fact as well that the properties of rheology possess other defining factors such as the formulation type for biopharmaceuticals, and internal sample variations like protein stability and concentration.


Another essential thing about rheological property test 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. When it comes to the type of rheometer being used for measuring these properties, it depends on the relevant sheer rates as well as timescales, with the inclusion of viscosity and sample sizes. 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. Regardless of whether the material is flowing, or is actually being deformed, rheology will be involved with all that. We want you to know as well that rheology is defined as the science of the flow as well as the deformation behavior of the 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.


As what we mentioned above, the tool that is used in measuring the properties of rheological properties test is the rheometer. As for the properties of rheology that are measured by a rheometer, they have something to do with the deflection angle of the measuring bob and the torque.
