What is Application of Powder Coatings. A Bibliographic Review to Obtain a Calculation System for the Design of a Conventional Fluidized Bed about?

Metallic substrata may be protected against aggressive agents by means of products working by "barrier effect", by solvent based paints of high solid contents, by solventless paints or by powder coatings. In the last case, film formation may be made by curing or sintering the powder, which was deposited by means of a fluidized bed. Although the fluidization of particulate solids and pneumatic transport theory is useful for powder coatings, particular attention should be paid to the characteristics of the material to be used, which determine their own requirements for the fluidized bed operation. Starting from the formulation and elaboration of powder coatings and from an adequate selection of particle size distribution, quantity and weight of each component (that is, each one of the granulometries of the final mixture), particle properties such as softening point, glass transition temperature, etc., were determined. Joining this data with the air characteristics at working temperature (density, viscosity, etc.), the calculation of apparent density and "viscosity" of static bed may be made, thus obtaining the main part of the design theoretical initial values. This aspect is studied
