Soaking method and technological process of chain link fence
Soaking method and technological process of chain link fence:
Dipping hook net is one of the methods to prevent corrosion. The powder impregnation method, which originated from the fluidized bed method, is used for oil contact decomposition on the Winkel gas furnace. The solid-gas two-phase contact technology has been developed and gradually applied to metal coatings. So it is sometimes referred to as a fluidized bed coating process. In this process, the powder coating is added to a container with a porous bottom, and the powder at the bottom is sent into the treated compressed air through a blower, resulting in powder The coating rotates and reaches fluidization. Evenly distributed finely dispersed powder.
We know that the fluidized bed is the second stage of the solid fluid state. On the basis of a fixed bed, the flow continues to increase, the bed initially expands and loosens, the initial height of the bed increases, and each powder particle floats, so it moves to a certain extent out of the original orientation, and then enters the fluidized bed period. The height of the fluidized bed increases with the increase of gas velocity, but the pressure does not increase. The change of flow velocity within a certain range does not affect the specific power required by the fluid. This is a feature of the fluidized bed, and it is this feature that is used to implement the coating technology. The uniformity of the powder fluidization in the fluidized bed is the key to ensuring the uniformity of the coating. The fluidized bed used in powder coatings belongs to vertical fluidization, and the amount of fluidization must be found through experiments, and coating can usually be carried out.
