“Teflon spraying mold” What is the role of Teflon mechanical parts spraying?
Teflon spraying is actually very common in our daily life, and it is also widely used, such as the food industry around us, used in automobiles, used by ordinary people, and used in the military. The shadow of fluorocarbon spraying is the most common application in our lives on some mechanical parts. In fact, the Teflon coating has played a role. There is anti-sticking on the spraying, and sometimes it also needs anti-corrosion function, but there are It has a smooth effect at times, and so on. The seemingly high-end things are actually very common in our lives! Teflon coating can play a very important role in the position that we can’t see with the naked eye!
“Teflon spraying mold” What is the role of Teflon mechanical parts spraying?
The Teflon spraying process is divided into the preparation of workpieces, (wet) dispersion coating spraying, monotony, and sintering steps:
- Preparation of workpiece: In order to obtain satisfactory surface adhesion on the surface of the workpiece, it is necessary to first remove all the grease on the surface to be coated. We dissolve the grease with an organic solvent and warm it to about 400°C to allow it to evaporate completely. Next, the workpiece is cleaned and roughened by mechanical means of sandblasting. The ability of the coating to contact the surface of the workpiece can be improved by using an adhesive (primer).
- (Wet method) Dispersion coating spraying: The spray coating materials must be uniform. Coating thickness depends on the coating system chosen; coating thickness may vary from a few microns to 200 microns (0.2 mm). 3. Monotonous: Heat the wet coating in an oven at a temperature below 100°C until most of the solvent has evaporated.
- Sintering: The process of sintering is to heat the workpiece to a higher temperature until an irreversible reaction occurs: the coating material melts and forms a network structure with the bonding agent.
