Fundamentals of Dry Coating in Fluidized Bed

Book Description
This thesis is devoted to the study of a novel dry coating method in fluidized bed - Dry Coating of Particles in Spouted bed (DCPS). The main objectives of this work were to study the feasibility of the process, both quantitatively and qualitatively, and to compare the results with coating by conventional mechanical mixing. Aerosol mechanics is applied to account for the following: 1) collision between the guest and host particles in a spouted bed (analysis of guest-host particle inertial fluid-dynamic interaction), and 2) to show how collision efficiency of guest particles with host particles affects the coating efficiency. An equation for relating coating efficiency to collision efficiency was derived. This equation predicts high coating efficiency for large-size guest aggregates and low coating efficiency for small-size guest aggregates. The experimental results confirmed the above predictions. It was established that large-size guest aggregates deformed during collision in the spouted bed resulting in patches over the surface of the host. This deposition mode results in large surface coverage. It was also established that the relative variation of coating among coated host particles by this method was very low. The relative variation of patches over the coated host surface was very low and from literature survey it was found that single particle coating resulted in non-uniform distribution over host particle surface [10]. Dry coating, by conventional mechanical mixing was investigated and compared with the novel dry coating method proposed in this thesis. This investigation demonstrated that coating by mechanical mixing resulted in non-uniform coating and harmful manifestation of guest particle agglomeration during the mixing process.

Fluidized-Bed Reactors: Processes and Operating Conditions
Author: John G. YatesPublisher: Springer
ISBN: 3319395939
Category : Science
Languages : en
Pages : 214
Book Description
The fluidized-bed reactor is the centerpiece of industrial fluidization processes. This book focuses on the design and operation of fluidized beds in many different industrial processes, emphasizing the rationale for choosing fluidized beds for each particular process. The book starts with a brief history of fluidization from its inception in the 1940’s. The authors present both the fluid dynamics of gas-solid fluidized beds and the extensive experimental studies of operating systems and they set them in the context of operating processes that use fluid-bed reactors. Chemical engineering students and postdocs as well as practicing engineers will find great interest in this book.
Fluidized-bed Coating with Plastics

ISBN:
Category : Corrosion resistant materials

Pages : 254
Book Description
This report on the relatively new field of fluidized-bed coating with plastics is intended to give military agencies and contractors a good idea of the possibilities and limitations of the technique. In the normal use of the process a metal part is heated to a temperature somewhat higher than the melting point of the resin powder with which it is to be coated. Upon immersion of the preheated metal part into a bed or bath of resin powder, usually kept at room temperature and fluidized by a current of air, the powder particles are fused onto the surface of the part. Postheating may or may not be necessary to smooth and/or cure the coating. This report has detailed information on 139 references, including 39 foreign and American patents. (Author).
