(Summary description)Choose a film with a moderate width and thickness; due to the complicated shape of the aluminum alloy extrusions, the wide and narrow outward appearance, it is easy to blow up the flash, reducing the covering ability of the film and affecting the spraying quality. If the film is too narrow, it cannot be covered and obviously cannot be sprayed. On the other hand, when choosing the thickness of the film, as long as it can cover and have elasticity, it is not necessary to choose a film that is too thick, because a film that is too thick will increase the production cost of aluminum alloy extrusions processing, and it is not necessary.

(1) Choose a film with a moderate width and thickness; due to the complicated shape of the aluminum alloy extrusions, the wide and narrow outward appearance, it is easy to blow up the flash, reducing the covering ability of the film and affecting the spraying quality. If the film is too narrow, it cannot be covered and obviously cannot be sprayed. On the other hand, when choosing the thickness of the film, as long as it can cover and have elasticity, it is not necessary to choose a film that is too thick, because a film that is too thick will increase the production cost of aluminum alloy extrusions processing, and it is not necessary.

(2) Spray in time after filming. After the profile is filmed, it should be sprayed in time, the shorter the parking time, the better. If the parking time is too long, because the adhesive on the film is dry and loses its viscosity, the film is peeled off after the wind blows, which causes difficulty in spraying. Therefore, in order to ensure the quality of the film and spraying, generally the parking time after filming should not exceed 16h.

(3) Choose a film with moderate viscosity. In the processing and production of two-color aluminum alloy extrusions, the reasonable choice of film is the key. If the viscosity of the film is too low, it will not stick. The film is easy to fall off, which brings considerable difficulty to spraying. The viscosity of the film is too large, indicating that there is more glue on the film. When the film is torn off, it is easy to stick the glue on the profile to affect the surface quality of the profile. The composition of the paint is the same as or close to the paint composition, which can reduce the effect on the color of the paint film.
