Galvanized chain link fence useful
Chain Link Fence method and technical process:
On the hook flower network is one of the methods of anti-corrosion dip, and now the domestic practice is more sophisticated: powder dip method, which originated in the fluidized bed method, the so-called fluidized bed is the beginning of the Wen Keller gas stove Applied to the oil touch differentiation, and then developed a solid gas two-phase touch technology, and later gradually used for metal coating. It is sometimes called the "fluidized bed coating method", the practice of the powder coating is involved in the bottom of the porous porous container (flow tank), the blower from the bottom of the compressed air through the treatment, the powder coating flip to reach the "flow Status. " Into a uniform distribution of fine powder. In this case,
It is known that the fluidized bed is the second period of the solid flow regime (the first period is a fixed bed period and the second period is the air transport period), the flow rate (W) is continuously increased on a fixed bed basis, Loose,
The bed height starts to be added, and each powder particle is floated and moved away from its original position for a certain degree of movement, during which time it enters the fluidized bed. Bc section of the fluidized bed powder layer expansion, the height (I) with the increase in gas velocity increases,
But the bed pressure (△ P) does not increase, within a certain range of flow rate without affecting the unit power required for the fluid, which is the characteristics of fluidized bed, is the use of this feature to carry out coating technology .
Fluidized bed fluidization uniformity of the situation is to ensure uniform coating of the key. In the powder coating with the fluidized bed is a "vertical fluidization", the number of fluidization must be found by experiment, generally can be coated, the fluidized bed suspension rate of up to 30 ~ 50 / RTI & gt;
For example: Fence chain through the degreasing preheated to the melting point of powder coating above the impregnated into the fluidized bed will be evenly after the plastic powder adhesion, and then cross-linked plastic flow of plastic-polymer composite products.
