Other Behavioural Properties

Utilising the dynamic methodologies of the FT4 Powder Rheometer, and good experimental design, it is possible to investigate a number of other behavioural properties of powders. These include: -

Caking
Powder consolidation with time

Graph showing the flow energy when differing amounts of water are added to a powder sample 

Moisture
The influence of free moisture on the behaviour of the powder

Graphic showing how different types of particles will segregate themselves in a powder sample 

Segregation
The potential for particles to rearrange according to their size / density 

 

Graphic showing the effect of increasing stress on particle attrition, as stress increases particles are more likely to break apart 


Attrition
Particle friability, resulting in changes in particle size, shape and surface area

Electrostatics
Changes in behaviour as a function of electrostatic charging

Graphic of Agglomeration 

Agglomeration
The formation of agglomerates from primary particles, usually as a function of being processed
