deagglomeration

deagglomeration

[‚dē·ə‚gläm·ə′rā·shən]
(chemical engineering)
Size-reduction process in which loosely adhered clumps (agglomerates) of powders or crystals are broken apart without further disintegration of the powder or crystal particles themselves.

Thinky nanotechnology includes the Thinky NP-100 Nano Pulveriser for breaking up particles using impact fragmentation, taking larger particles down to nano-size, and the Thinky PR-1 Nanoparticle Dispersion Machine for nanoparticle dispersion and deagglomeration of CNT, graphene and other 2D nanomaterials.
Two saw-tooth, high-speed disperser blades impart shear for fast powder wetout and thorough deagglomeration.
The new four-gallon Planetary Dual Disperser (Model PDDM-4) is equipped with two High Viscosity Blades and two High Speed Dispersers; all four agitators rotate on their own axes while orbiting the vessel, ensuring rapid powder wet-out and deagglomeration.
The authors demonstrated size-related translocation with the smaller 7 nm primary gold particles translocating more than the 20 nm primary gold particles, suggesting deagglomeration of the 45 nm agglomerates in the lung.
Many powders, including sodium chloride and ammonium sulfide, can harden into a solid block that cannot be dispensed into process liquids without deagglomeration, " said Scott Patterson, ILC Dover vice president of commercial sales.

The deagglomeration of the particles and the formation of the preferential flow layers promote a decrease in viscosity with an increase in the shear rate.
The Ross Batch High Shear Mixer is designed for general purpose mixing, powder wet-out, deagglomeration, dispersion, emulsification and homogenization.
This mid-range mixer is also suitable for bulk powder dispersion, deagglomeration, gelation, reaction acceleration, suspension and processing high-viscosity mixes.
MegaShear ultra-high shear mixers are patented inline rotor/stators for high-volume and high-throughput deagglomeration, emulsification and homogenization requirements.
