Fluidized Bed

The Fluidized Bed system involves a booth and an embossing base under which air can go but the powder cannot. Compressed air fed into this base lifts the powder and gives a boiling appearance. (as the powder tanks in gun systems). The surfaces to be coated are immersed into the boiling powder and removed by rail systems circulating above the booth. Then, the powder-coated surfaces are transferred to the ovens. The powder can adhere to the surface in two different ways. In the first scenario, surfaces that will be coated are heated and the powder adheres to the surface with the heat. In the second, the powder is electrostatically charged and the surface that will be coated is grounded. The surface is coated with the powder based on the principle that negative and positive charges attract each other.
