In the case of ECMAE, rupture is the governing mechanism of agglomerate disintegration in the range of low strain (up to e = 4.4).
As both phases (acetone and aqueous) contained the diluents, then it is likely that it was distributed both inside the agglomerates (intragranularly) and outside the agglomerate (extragranularly), attached to the surface.
The eigenvector space is used to find the similarity among nodes and agglomerate the most similar nodes to make a new combined node in a network graph.
Agglomerates are formed through the adhesion or cohesion of smaller primary particles.
Its application in cork agglomerate can add value to these substrates making them more efficient in extreme weather conditions.
It is easy to see that at these conditions one monochromatic (dark) magnetic region corresponds to one surface agglomerate; that is, at H = 4000 Oe the magnetization of every magnetic anomaly orients itself along the applied magnetic field and every surface agglomerate becomes a magnetic monodomain.
These experiments illustrate the importance of correlating methods--and focusing on the purpose when developing a method for determination of particle sizes: Are you interested in the primary particles and/or the agglomerates? The tendency to agglomerate influences the dissolution rate--and it might further influence the manufacturing properties.
Downstream of the plant a plastcompactor operates in order to transform the film material into agglomerate with excellent flowing properties and high bulk density.
Agglomerate formation was studied in six samples taken from different batches of an inhalation drug suspension, where primary particle size was generally less than 10 microns in diameter.
Dispersive mixing is governed by a competition between the hydrodynamic forces acting on the particulate agglomerate and the cohesive forces holding that agglomerate together.
Small clay particles can agglomerate with polyvinyl acetate (PVAc) to form neutral-buoyancy aggregates.
The unit is designed to process sticky, slow-to-crystallize copolymer pellets that have a tendency to agglomerate between the glass transistion point and the final crystallization point.
