Construction requirements for powder coating
of aluminum profiles
Aluminum profile Powder coating surface treatment is the powder coating is
sprayed to the surface of the aluminum profile with powder coating equipment
(electrostatic spray machine), under static action, the powder will be evenly
adsorbed to the surface of the aluminum profile, forming a powder like coating.
The powder coating is cured by high temperature baking leveling to become the
final coating with different effects (different types of effects of powder
coating).
1.In order to give full play to the
special properties of powder coating and extend the life of coating film,
aluminum profile surface is first strictly pre-surface treatment.
2. When spraying, the aluminum profile
must be completely grounded to increase the spraying efficiency of the powder
coating
3. For coatings with large surface
defects, the conductive putty should be scraped to ensure the smoothness and
smoothness of the coating film
4. Aluminum profiles after powder coated
need to be heated curing, curing conditions to powder product technical
indicators, but must fully guarantee its curing temperature and time, to avoid
lack of curing caused by quality accidents.
5. Inspect the aluminum profile immediately
after coating.
6. Recycled powder must be screened to
remove debris, according to a certain proportion of the new powder mixing
effect.
7.Powder supply barrels, powder rooms
and recycling systems should avoid the contamination of other different color
powders, so every time the color change must be blown clean.
