Generally, capillary rheometers are used to measure melt properties at higher shear rates compared to rotational rheometers, allowing determination of flow behavior under typical processing conditions. Thermoplastics can be characterized using a Kinexus Rotational Rheometer, but also with the Rosand Capillary Rheometer.
Mit modernen rheologischen Methoden ist es möglich, die Fließeigenschaften von Batteriepaste unter Prozessbedingungen zu messen. Zu diesem Zweck verwenden wir das KINEXUS Rotationsrheometer und das ROSAND Kapillarrheometer. Sehen Sie sich unser aktuelles Webinar an und erfahren Sie mehr.
In this episode, will correlate the results that are relevant for the filament extrusion to the melt rheology inside the material extrusion head using the capillary rheometer.
Based on our past episode about analysis methods used in material extrusion (ME), we are going to talk about the relevant parameters for production of the filament used in ME today. Learn how to measure the shear-dependent viscosity using the ROSAND capillary rheometer.
In Powder bed fusion there is no flow and no shear rate. For powder coalescence, the local molecular motions and entanglements across the layers are important. So today, Dr. Natalie Rudolph will be focusing on the rotational rheometry.
Using modern rheological methods, it is possible to measure the flow properties of battery slurries under processing conditions. For this purpose, we use KINEXUS Rotational Rheometer and ROSAND Capillary Rheometer. Watch our latest webinar and learn more.
It is imperative to understand how thermoplastics flow when being processed. Learn about the time dependence of flow properties and other important characteristics.
One year ago, NETZSCH Analyzing & Testing announced the extension of its product portfolio with the Kinexus rotational rheometers and Rosand capillary rheometers. Our Rheology Application Specialists look back on the highlights and hint at the important topics coming up in 2021.
The Rosand RH2000 Capillary Rheometer is an instrument that analyzes the flow properties of any type of material under processing conditions, like high forces and high speeds. Our rheology specialist, Torsten Remmler, shows how to prepare the instrument for an experiment and gives important tips when operating it.
Traditionally, capillary rheometers have been used to measure the shear viscosity and elasticity of viscous materials at high shear rates. In this article and video, Natalie Rudolph (PhD) explains the working principle, parameters and their relations of the capillary rheometer.
