Understanding Batch Variability in Spray Coating Applications
Introduction In spray coating applications, a fine powder, typically a polymer, is drawn from a storage device before being fluidised and ejected through a charged nozzle onto a substrate. It is essential that the powder can be effectively and consistently fluidised, without the formation of agglomerates that may block the nozzle and affect the charging […]
Enhance Powder Flow Understanding with Direct Measurements of Powder-Air Interactions
The ease with which air can flow through a powder bed reflects the strength of particle-particle interactions, and specifically highlights cohesive interparticle forces. Because air accounts for a large volume fraction of any bulk solid, specific characterization of powder-air interactions can lead to improved understanding of packing behavior in bulk solids and flow of bulk […]
Powder Caking: Understanding Different Caking Behaviors and the Influence of Humidity Cycling
Caking affects many powder processors, particularly where large volumes of powder are stored or transported for long periods, or where interaction between the powder and the environment are prevalent. However, caking is not a simplistic process and does not present itself equally throughout a powder bed, instead forming distinct patterns and modes as a function […]
Optimizing AM Feedstock Reuse with an FT4 Powder Rheometer
AM powder users, reprocessors and manufacturers share the need to maximise product quality and yield from feedstock while minimising waste of resources. Strategies for powder reuse, through direct recycling or rejuvenation processes, can significantly improve the output of raw materials, but the effectiveness of these strategies can massively vary across different materials and batches. Powder […]
Powder Flow Characterization for Optimizing Processes in Industry and Research
Powders are used extensively across a wide range of industries- they possess many valuable properties and benefits. However, they are also challenging materials with bulk flow properties that are difficult to predict, even within simple process operations. They change their behavior and performance depending on their environment- shear rate, stress conditions, storage duration, humidity, etc. […]
