Teflon spraying process brief introduction
About teflon spraying process:
1. Dispersion coating: the processing method of dispersion coating is to make the coating material evenly distributed in the solvent to form a dispersion liquid (solid material mixed in the liquid), a wet processing. The mixture is atomized by high-pressure air and sprayed onto the workpiece surface.
2. Processing steps
The processing steps of dispersion coating are divided into the following steps: workpiece preparation, (wet) dispersion coating spraying, drying, sintering
3. Preparation of workpiece
In order to obtain adequate surface adhesion on the surface of the workpiece, all grease must be removed from the surface to be coated. We use an organic solvent to dissolve the oil and heat it to about 400 degrees to evaporate it completely. Next, the mechanical method of sandblasting is used to clean the parts and roughen the surface. The ability of the coating to bond to the surface of the workpiece can be improved by using a bonding agent (primer).
(wet) dispersion coating spray
Spray coating material must be uniform. The coating thickness depends on the coating system used; Coating thickness may vary from a few microns to 200 microns (0.2 mm).
4. Dry
Heat the wet coating in an oven at a temperature of less than 100 degrees until most of the solvent has evaporated.
5. The sintering
Sintering is the process of heating the workpiece to a high temperature until an irreversible reaction occurs: the coating material melts and forms a network with the bonding agent.
6. Powder coating
An overview of the
The processing method of powder coating is a dry processing, in which the coating material used is extremely fine solid particle form. By using this coating method, the use of solvents and subsequent divergence of the coating during attachment are avoided.
7. The processing
Use appropriate methods to attach micropowder coating particles to the workpiece. The coated powder is then melted in an oven.
