Chain link fence with plastic coated

Chain link fence are used in many places, such as highway fence, stadium fence, park fence, entertainment city fence, etc., which are widely used. What are the methods and processes for plastic coated the chain link fence?

One of the commonly used anti-corrosion methods for chain link fences is the dipping method. The powder dipping method originated from the fluidized bed method. The so-called fluidized bed was originally applied to the contact decomposition of petroleum in the Winkler gas generator, and then developed a solid-gas two-phase contact process, and then gradually used for metal coating Plastic aspect. The powder dipping method actually puts the powder coating into a porous and air-permeable container (flow tank) at the bottom, and the treated compressed air is fed from below by a blower to turn the powder coating to a "fluidized state". Become a uniformly distributed fine powder.
 

Everyone knows that the fluidized bed is the second stage of the solid fluid state (the first stage is the fixed bed stage, and the second stage is the air conveying stage). On the basis of the fixed bed, the flow rate (W) continues to increase, and the bed starts to expand. With loosening, the height of the bed layer begins to increase, and each powder particle is floated, and thus moves away from the original position to a certain extent, and then enters the fluidized bed stage.
 

The uniformity of the powder fluidization state in the fluidized bed is the key to ensuring the uniformity of the coating film. The fluidized bed used in powder coating belongs to "vertical fluidization". The fluidization number must be found through experiments. Generally, it can be coated. The suspension rate of the powder in the fluidized bed can reach up to 30-50 %.
