Fluidized Bed Coating

Fluidized bed coating is a versatile and efficient coating process that can be used to produce a wide variety of coatings for a variety of applications. In fluidized bed coating, the particles to be coated are suspended in a stream of low-pressure air. This is done by passing air through a membrane and into a bed of coating powder This flow of air gently lifts the powder off the bottom of the bed and simultaneously mixes with the powder to create a fluid like pool.

The metal components are preheated in an oven and transported to the fluidized bed.  They are quickly immersed into the bed of fluidized powder and are fusion bonded to the part.  The powder quickly encapsulated the heated piece of metal and coating thickness is determined by a combination of metal temperature and time immersed in the fluidized bed. Metal parts are placed back in the oven to post cure.

In addition to fluidized bed coating, Desert Coating Solutions uses liquid dip tanks to achieve a similar process.  Liquid resins are used to fill tanks.  Metal parts are preheated and dipped into the tanks.  Once again, both temperature and time in the tank determine the coating thickness.  Parts are then post cured in the oven to solidify the coating.

Key features of fluidized bed coating and electrostatic fluidized bed coating:

  • Thick, uniform coatings: Both fluidized bed coating and electrostatic fluidized bed coating can produce very thick, uniform coatings that are resistant to corrosion, wear, and other environmental factors.

Electrostatic fluidized bed coating

Electrostatic Fluidized Bed Coating is a variation of fluidized bed coating that uses an electrostatic charge to improve the adhesion and uniformity of the coating. In this process, the coating material is first sprayed onto the particles in the fluidized bed. The particles are then charged with a positive or negative charge, depending on the type of coating material being used. The charged particles are then attracted to the surface of the substrate, which is typically grounded. This helps to ensure that the coating material is evenly distributed and that it adheres well to the surface of the substrate.

Advantages of electrostatic fluidized bed coating

  • Improved adhesion: Electrostatic Fluidized Bed Coating can improve the adhesion of the coating material to the surface of the substrate. This makes the coating more resistant to chipping, peeling, and other forms of wear.
  • Less waste: Electrostatic Fluidized Bed Coating uses less coating material than fluidized bed coating. This can save you money and reduce environmental impact.
  • Uniform coating: Electrostatic Fluidized Bed Coating can produce a very uniform coating, even on complex shapes.
