Particle Density
Dow Global Technologies LLC
density determination
Polyolefin powders having a small mean volume average particle size are useful in 3D-printing techniques such as powder bed fusion
where successive layers of powder are laid down and sintered to form a 3-dimensional end product. Powder bed fusion requires flowable powders to enable easy transport and loading of the powders. Powder bed fusion also requires powder having a small mean volume average particle size. A polyolefin powder having a small mean volume average particle size is conventionally formed in one of three ways: (i) spray drying an aqueous polyolefin dispersion with small particle size to remove water and obtain aggregated dry powder; (ii) coagulating or aggregating a small particle size aqueous polyolefin dispersion and filtering the aggregate to remove water; or ( iii) mechanically grinding the polyolefin to the desired size
such as through cryogrinding. When produced via spray drying and/or the coagulating oraggregating process
the resulting powder contains agglomerates with voids that are not fully dense
which deteriorates the mechanical properties of an end product formed from said powder. When produced via mechanical grinding
the resulting powder has a broad particle size distribution and the particles have irregular shapes (compared to spherical shapes).

Smooth polystyrene (PS) and polyamide 12 (PA 12) surfaces were produced via an injection molding process followed by a smoothing process and subsequently treated with O2 plasma to increase the number of polar groups capable of hydrogen bond formation on the surface. The presence of related groups was evident from XPS and contact angle measurements. The sample topographies were investigated by AFM. The plasma treatment allowed the joining of the substrates without adhesive by pressing the substrates together below or around Tg. Notably

Ageing effect on the microstructure of clay gel
Laponite EP
an organically surface coated laponite
as an alternative of xanthan in product formulation. Its combination with bentonite in agrochemical formulation showed similar rheological behaviour as the commonly used xanthan - bentonite combination. Laponite EP and bentonite display some synergism: analogous rheological properties could not be achieved using each clay alone or using a non-coated laponite RD - bentonite blend. cropscience
agrochemistry
The sedimentation profile obtained during ageing shows that all gels collapse
as seen by the drop of their surface in figure 6.10. However
for bentonite and the mixture we see a homogeneous decrease of the transmission throughout the height of the gel indicating an increase of the concentration of the clay. This is consistent with a shrinkage of the gel. However
for attapulgite
the transmission decreases at the top of the gel but stays constant at its base
see figure 6.10a. This is in contradiction with the consolidation theory developed by Michaels and Bolger According to these authors
sedimentation happens when the static pressure outweighs the yield stress. In that case
the network starts collapsing at its base
thus increasing the volume fraction and strengthening the gel there. There is also the formation of a constant density layer
which collapses up to a point where the static pressure is equal to the yield stress. This theory was developed for Kaolin which is a non swelling clay with a shape similar to a platelet. We do not necessarily expect bentonite to follow such a theory as it is a swelling clay
but it may be more applicable to attapulgite. In our system
evaporation of water might have happened as well
affecting the top of the gel first as it is closer to the surface

Basically
separation processes can be described by extended Stokes law taking into account volume concentration of disperse phase (hindrance) and rheological behaviour of continuous phase. To deduce separation behaviour under high gravity in centrifuges one can assume that separation velocity scales linearly with acceleration in Newtonian liquids. Situation in non-Newtonian liquids is much more complex
however
this is often characteristic for industrial separation tasks
e.g. during downstream bioprocessing. Modelling of the separation processes gets even more complicated when taking into account polydispersity of real-world suspensions. To contribute to a better understanding
model investigations were performed with monodisperse polymer particles (6 and 15 µm) and their bidisperse mixtures in aqueous solutions of carboxmethyl cellulose (CMC). Measurements were conducted as function of centrifugal acceleration and at gravity

a thinner shell leads to higher surface areas
lower isoelectric points
and higher magnetizations. However
thick layers prevent oxidation and lead to stabilization. The coating thickness influenced the binding of the cationic peptide lasioglossin
with a maximal loading of 0.23 g g−1 for the smallest particles. This knowledge can be used to specifically design particles for usage with a cationic tag system in biotechnology or drug delivery with antimicrobial peptides.
