Mechanical paint spraying method
2020年12月24日 日常First, the top ranking spraying-mist spray
1. Viscosity-14-16 seconds (20°)
2. Spit volume--1/2-2/3
3. Painting pressure--4.0-5.0 bar
4. The distance of the spraying tool-25-30cm
5. Standard spray blessing-fully open, technicians are spraying
6. When spraying-slightly faster
Spray the whole body loosely and thinly to initially merge with the underlying coating film. At the same time, confirm whether there is a shrinkage hole. If there is, increase the air pressure (6.5 bar) on the area slightly and apply concentrated spraying to fill the shrinkage hole.
2. The second spray-fixed color spray
1. Viscosity-14-16 seconds (20°)
2. Discharge volume--2/3-3/4
3. Painting pressure-4.0 bar
4. The distance of the spraying tool-25-30cm
5. Standard spray blessing-full open
6. When spraying-slightly faster
The second spray is used to fix the color. Don’t pay too much attention to the spray marks and metal stains, just spray one layer to fix the color. The moving speed of the spraying tool is better. Repeating the spraying once can generally solve the problem. If the color is not enough, you can use the second spraying method to spray again.
3. The third spray-correction spray
1. Viscosity-11-13 seconds (20°)
2. Spit volume--1/2-2/3
3. Painting pressure-4.5-5.0 bar
4. The distance of the spraying tool-25-30cm
5. Standard spray blessing-full open
6. When spraying-slightly faster
This spraying is to trim the paint stains and spray marks left after the fixed-color spraying, and make the mechanical texture better.
main feature
(1) Contamination resistance.
(2) Durability: including freeze-thaw resistance, scrubbing resistance, and aging resistance.
(3) Alkali resistance: The decorative objects of paint are mainly alkaline materials, so alkali is an important characteristic of paint.
(4) Low film-forming temperature: Each coating has a low film-forming temperature, and different coatings have different low film-forming temperatures.
