Über dieses E-Book

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).
