Spray drying - Wikipedia

Spray drying is a method of producing a dry powder ... There is a single source of drying air at the top of the chamber (see n°4 on the diagram). In most cases the air is blown in the same direction as the sprayed liquid (co-current). A fine powder is produced, but it can have poor flow and produce much dust. To overcome the dust and poor flow of the powder, a new generation of spray dryers ...

Powder Rheology and Powder Flow Testing

Powder Flow Function. Unlike liquids and semi-solids, powders display flowability that is dependent upon the applied consolidating pressure. As pressure is increased from, for example, the weight of a column of material in a silo, hopper or vessel, the yield stress of the material at the bottom increases, resulting in decreased flowability.

Physical vapor deposition - Wikipedia

Physical vapor deposition (PVD), sometimes (especially in single-crystal growth contexts) called physical vapor transport (PVT), describes a variety of vacuum deposition methods which can be used to produce thin films and coatings. PVD is characterized by a process in which the material goes from a condensed phase to a vapor phase and then back to a thin film condensed phase.

PTFE Coating Process - PTFE Applied Coatings

Some PTFE coating systems can be of a multi coat type, which includes both primers and mid coats being applied before the final coat. Typical film thicknesses are from 10 to 100 microns thick, for example from 20. to 50 nm thick. . A usual characteristic of the process is that the aqueous PTFE coatings are effectively self-limiting in thickness. However, PFA (powder) coating can be deposited ...

Fluidized Bed flow regimes rev1 - Rowan University

In the case of fluidized bed coating, air is passed through a bed of polymer particles. When the frictional force acting on the particles, or pressure drop, of the flowing air through the bed equals or exceeds the weight of the bed, the powder particles become suspended and the bed exhibits liquid-like behavior. As shown in the figure below, at gas flowrates less than the fluidization velocity ...
