* fines accumulation on 140 to pan sieves is an ongoing process arising from either grain attrition or stable fine agglomerates
Additional heat in this area-300[deg.]C is not uncommon-an prevent secondary agglomerates
. Figure 3 compares micrographs of 5-micrometer microtome cuts of 20% phthalocyanine blue dispersed in polypropylene in a 60-mm twin-screw extruder at 100-rpm screw speed, 90 lbs/hr, and at 220[deg.]C and 300[deg.]C barrel temperatures in the melting zone.
After 30 min of stirring, agglomerates
thus obtained were separated by filtration and dried.
Mean particle size and agglomerates
density from optical microscope images were analyzed to evaluate the MWCNT dispersion.
for carbon black, however, have been shown to be over five microns in size.
of Wisconsin, discussed particle and agglomerate
size distributions and their relationship to clay and fines in reused green sand.
CNTs tend to form agglomerates
(14), (16), (23), (27).
A rubber sample is placed in a guillotine sample cutter and cut with a razor blade, exposing the peaks and valleys due to the undispersed carbon black agglomerates
. The fresh-cut surface is then placed under the Xi-100 objective and quickly scanned.
Grain size distribution, organics present in binders and agglomerates
are among the factors that could reduce strength and curing rates.
When the CNTs concentration reaches 10 wt%, formation of several large agglomerates
of 600-800 nm in size is observed.
The rate of dissolution of the drug from the agglomerates
or compacts thereof can be improved and modified by using suitable excipients during the process of preparation of agglomeration.
