Webinar Series on Demand: Rheology

The Basics of Viscosity

In this webinar one of our rheology experts, Philip Rolfe, will introduce the basics of viscosity. Philip will cover the different measurements possible with a rheometer to measure viscosity and some common artefacts to look out for in the results. The webinar will also cover different measuring geometries suitable for measuring the viscosity of different sample types.

The Rheology of Dispersions

In this webinar one of our rheology experts, Philip Rolfe, will introduce the rheology of dispersions. Philip will discuss the importance of rheology in the stability of dispersions and what factors to consider when suspending materials in a liquid medium. Topics covered will include; the effects of varying the particle size, surface charge and shape of particles in a sample. Common test methods will be discussed including yield stress testing, viscometry, oscillatory rebuild time and even the use of rheo-microscopy to view dispersions in real time.

Introducing Curing Measurements on a Rheometer

In this webinar one of our rheology experts, Adrian Hill, will introduce how to perform measurements on curing materials with a rotational rheometer. The webinar will cover how rheology is the perfect technology to monitor the huge changes in material properties as they cure from what can be low viscosity liquids to effectively solids. Good measurement practice on how to get the most out of this challenging application will be discussed, including how to identify the different curing regions, such as those detailed in ASTM D4473; gel time, minimum viscosity, reaction rate and final cure.

Rheology of Lotions and Emulsions

In this webinar one of our rheology experts, John Casola, will discuss the rheology of lotions and emulsions. The webinar will cover the different rheological measurements to study these types of samples, in particular how to capture meaningful results relating from production to storage, product delivery and application. Measurements include different viscometry and oscillatory options, including troubleshooting for challenging samples.

Rheology of Battery Slurries

In this webinar we will give a short overview of the benefits of rheological analysis, emphasising the significance over viscometer testing, of battery slurries. Initially, general rheology results will be put into context with then specific discussion of the characterisation of LIB (lithium ion battery) slurries; an important intermediate step in manufacturing anodes and cathodes. This will detail the different rheological characteristics needed for the different processes and conditions that these slurries must be used under. The careful and delicate balance of contrasting properties will be considered – and hence material measurement needs – for stability, screen printing performance pre, post and during coating.
