PVC mixer tests Reproducibility and influence of test conditions.

 

A laboratory mixer is the ideal measuring tool for testing fusion behavior, compound stability, and processing behavior of PVC formulations. A laboratory mixer is very sensitive to any changes caused by the compound formulation or any changes in the dry blend components, such as the resin, additives used, and additional fillers. Laboratory mixers are also sensitive to changes that are caused by incorrect handling. To achieve reliable test results, it is imperative that the mixer is handled in a reproducible manner.

 

This application note shows examples of reproducible mixer tests and provides examples of how changes in the testing conditions influence measuring results.

 

For these investigations, the following equipment configuration

was used:

• Thermo Scientific™ HAAKE™ PolyLab™ OS RheoDrive™ 7 OS

• Torque sensor for HAAKE PolyLab OS, 400 Nm

• PolySoft OS Mixer Test and Data Evaluation Software

• HAAKE Rheomix 600 OS

• Roller rotors

• Pneumatic ram

• Sample material—rigid PVC dry blend (typically used to

produce window profiles)

 

 



RheoSense, Inc about Accurate Estimation of Injectability (Syringeability) from High Shear Viscosity Measurement.

In protein therapeutics, major resources are dedicated toward the development of self-injection formulations for:

• Sustainable Release

• Subcutaneous Injection

When sustainable release and subcutaneous injection are achieved, the concentration of protein inevitably increases, causing an increase in viscosity.

In this application note, we take a close look at how protein formulation viscosity affects the injection force, and we will demonstrate how to use the viscosity measurement to determine the necessary injection force required for the given solution.

Using the small sample viscometer, m-VROC™, from RheoSense, it is possible to accurately estimate the injection force necessary using data collected from viscosity measurements.


AFM Contribution Toward Battery Recycling by Measuring The Force Between Microbubbles and Flat/Rough Surfaces_Nanosurf (Switzerland)

This paper addresses the complex field of battery recycling and deals with the difficult task of recovering valuable metals such as cobalt, nickel and lithium from the residues of pyrometallurgical recycling processes.

 

However, a major scientific challenge has been to accurately quantify the wetting properties and adhesion force between EnAM crystals or more generally, particles and binding liquid droplets. To overcome this challenge, the FlexAFM in combination with the FluidFM® (Fluidic Force Microscopy) has proven to be a highly accurate tool that provides insight into the dynamics of wetting and adhesion at the microscale.

 

HAAKE Rheology-Raman Spectroscopy: Tracking emulsion stability_HAAKE (Germany)

 

The stress-strain response of complex fluids is closely linked to changes in their physical or chemical structure. That means rheological measurements are even more useful when combined with simultaneous measurement of physical or chemical properties affecting flow.

 

Raman spectroscopy is a powerful noninvasive technique to probe chemical information in many soft matter substances, including emulsions. Such samples are often sensitive to temperature and flow history, so simultaneous measurements are not only faster but help minimize variation and ensure reliable results.

• Investigate structural changes and mechanical behavior simultaneously

• Follow shear induced phase transitions

• Predict the stability of emulsions as a function of shear and temperature

• Study the kinetics of chemical reactions under defined conditions

Continuous twin-screw extrusion and rheological analysis of electrode slurries for lithium-ion battery manufacturing

Lithium-ion batteries (LIBs) are widely used in portable electronics, electric vehicles due to high energy density and long cycle life.  Manufacturing good slurry is one of a main process for making LIBs.

 

Advantages of Using Continuous Twin-Screw Compounding for Making Electrode Slurries 

1. Finer dispersion

Twin-screw extruders provide better distributive and dispersive mixing than dissolvers.

2. Reduced amount of solvents

Solvent drying and recycling is highly energy consumption.

Strong shear forces acting onto the materials allow to reduce the solvent content of electrode pastes.

3. Scalability 

Volume to surface ratio varies less than in batch mixers.

Good scalability from lab to production 

 

Rheological Analysis of Battery Slurries 

Rotational and oscillatory rheometer enables the quantification of the viscoelastic properties needed to 

Verify a proper mixing and a homogeneous distribution of active components within the electrode slurries.

Predict storage behavior and stability.

Understand behavior during the coating process.

 

 

Slot Die Coating for Battery Development

Batteries are devices that convert stored chemical energy into electrical energy through electrochemical reactions. They are used in a wide variety of applications, including portable electronics, electric vehicles, and stationary energy storage systems.

 

Advantages of slot die coating:

Can compare across different size scales from lab-scale to pilot-scale

Alternative devices for small sample size

High reproducibility and switching between different coating parameters without loss of accuracy

Roll-to-roll adaptations of our alpha and sigma machines make scale-up to pilot production seamless

Full pilot-scale coating line with the ability to customize

 

At FOM Technologies, we offer a wide variety of slot-die coating products. Whether you’re coating electrodes, developing solid electrolytes, working under ambient conditions, or you require an inert glovebox environment or dry rooms, we can provide premium slot-die solutions to meet your specific needs.

Advanced simulation – deeper understanding for improved coatings design.

Analytical modelling utilizing the effective indenter concept for stress calculations is a powerful tool for getting the most out of nanomechanical and nano-tribological tests [1]. Key strengths of the NanoTest design (such as high lateral rigidity for straight scratch tracks, ultra-low thermal drift at elevated temperature etc.) enable production of high-quality artefact-free data to be used as direct input to the physical-based models. 

 

The detailed simulated stress distributions enable data to be interpreted more effectively. They can provide mechanistic information which can be the key to unlocking exactly where and why coatings systems fail in and fretting tests, and then to designing coatings with improved performance.

 Micro Materials have worked with SIO, an innovative modelling company who have developed these models and the accompanying intuitive software interface, to fully integrate this advanced modelling capability to the NanoTest system. 

 

In this Technical Note we illustrate some of the possibilities from combining the advanced modelling with the NanoTest data on hard PVD coatings and bulk metallic materials.

Studying the particle size distribution of a polystyrene suspension based on sedimentation.

Most suspensions are polydisperse systems, meaning that solid particles of various sizes are dispersed in a fluid. A particle size distribution study yields insights into the width of the particle distribution. Such studies enable the analysis of powders, granular materials, and particles suspended in liquids in great detail. Particle size distribution studies are used in research and quality control in many industries, including the cosmetics, pharmaceutical, and food industry. In this application note, a MultiScan MS 20 dispersion stability analysis system from the German manufacturer DataPhysics Instruments is used to analyze the particle size distribution of polystyrene particles in water.
