It is Jinhua fluidized bed coating process consisting of a porous separator and the container, a porous separator is divided into two parts of the container. Their work is this: the container section below the bulkhead pass into the air, compressed air through a porous separator so that the role of the air flow above the powder were not suspended up spray processing, and roll in the upper container, showing "boiling" state. Preheated workpiece through the "boiling" powder coated area achieve results. Preheating temperature of the workpiece can be slightly higher than the melting temperature of the powder. Cold spray is a metal spraying process, but it is different from the conventional thermal spray (spray processing speed flame spraying Tianjin, plasma spraying, detonation spraying and other traditional thermal spraying). It has many nicknames, such as supersonic cold spray, gas dynamic spray, cold spray, air force spray, fast painting, sports metalization, power spraying and power metalization and so on. It is not necessary to melt the metal particles sprayed steel spray processing, the temperature of the surface of the substrate coating does not exceed 150 degrees Celsius. Cold spraying cold spray theoretical basis is compressed metal particles accelerated speed to zero bound (supersonic), physical deformation of metal particles to the substrate surface occurs after Watch. Flat metal particles hit the substrate surface and securely attached to, the whole process the metal particles are not melted, but if there is no metal particles can not reach supersonic attachment.
