PVC coated process

Chain link fence is one of the anti-corrosion methods, domestic mature approach is: powder package method, it originated in the fluidized bed method, the so-called fluidized bed was originally on the winkler gas generator used in oil contact decomposition, then develop the gas solid two phase contact process, after gradually used in metal plastic coated.So sometimes still called fluidized bed coating method, the actual process is add powder coating to porous permeability at the bottom of the container flows (tank), by the blower from the bottom into the compressed air after processing, make the powder coating turning to "fluidized state".It becomes a finely distributed powder.

We know solid flow pattern of fluidized bed is in the second stage (the first stage for fixed bed, the second phase phase for air transportation), on the basis of the fixed bed to continue increasing velocity (W), bed expansion and loose, bed height increased, each powder particles float, and leave the original position for a certain degree of mobile, has now entered the stage of fluidized bed.BC period of powder in fluidized bed expansion, its height (I) increases with the increasing of gas velocity, but bed (delta P) does not increase, the pressure changes within a certain range velocity without affecting the fluid power unit, the this is the characteristics of the fluidized bed, it is to use this feature to applied on the coating process.The uniformity of fluidized powder in fluidized bed is the key to ensure the uniformity of coating.The fluidized bed used in powder coating belongs to "vertical fluidization", and the fluidization number must be found through experiments. Generally, it can be applied.

Plastic coated method is as follows: for example, hook flower net after degreasing preheated to the powder melting point above, plastic powder will be uniform adhesion after dipping into the fluidized bed, and plasticizing of polymer crosslinking flow pp.47-53 gangsu composite products
