The correct usage methods and precautions of the protective film for aluminum profiles

1. Preparation before film application

Before using protective film for aluminum profiles, you must first make adequate preparations. Preparing high-quality protective film is a key step, such as PVC or PE protective film suitable for different surface treatments. At the same time, place the aluminum product in a position that is conducive to wrapping the protective film so that subsequent operations can proceed smoothly.

2. Key points in the construction process

1. Choice of film pasting time: If aluminum profiles are to be pasted with film, they need to be pasted immediately after oxidation, and the placement time should not be too long.
2. Width control of film: The width of the aluminum profile film needs to be consistent with the cross-sectional width of the aluminum profile. If the width of the film is too wide, it will lead to loose fitting, warping, etc.
3. State during film application: The film cannot be deformed, otherwise it will shrink and result in no film coverage at both ends of the aluminum profile.
4. Treatment of special positions: If the veneer boundary of the aluminum profile is located at the edge of the aluminum profile groove during veneer application, the rough edge of the film should be pressed into the groove and the film should be pasted flat to prevent warping.
5. Response to different profiles: For aluminum profiles with thin walls or complex cross-sections, special treatment methods need to be adopted.

3. Matters needing attention after construction is completed

After the construction is completed, the protective film should be removed in time. Do not move the glass within three or four days after the glass film is installed on the aluminum alloy doors and windows, because it may contain moisture (the water has not evaporated yet), so it is best not to move it. Do not use water directly to clean the aluminum alloy door and window glass with the film within half a month after the glass film is applied.

4. Cleaning during use

Do not use any objects that can be hung on the aluminum alloy door and window glass with film, and do not stick stickers on the aluminum alloy door and window film. When cleaning aluminum alloy doors and windows, the cleaning agent should be lightly and evenly applied to the surface of the window film, and then the aluminum alloy door and window film should be gently wiped with a clean soft cotton cloth or a water-absorbing wipe. The water on the cotton cloth and the water-absorbing wipe needs to be wrung out. The pure external alcohol contained in the cotton cloth or the water-absorbing wipe will quickly dissolve large stains and greasy fingerprints. If the stain is not cleaned, spray the cleaning solution again, scrape the aluminum alloy door and window film horizontally from top to bottom with a soft scraper until it is dry, and wipe the edge of the aluminum alloy door and window film with a towel or rag.

5. Remove the residual glue on the protective film

If you have used adhesive or decals on aluminum alloy doors and windows, and want to remove the glue or adhesive left by these materials, you can use a soft clean cotton cloth dipped in acetone to gently scrub the contaminated area, and you can quickly remove the adhesive left on the aluminum alloy door and window film. A small amount of acetone will not damage the polyester film, but it can immediately dissolve and completely evaporate the adhesive and most spray paints.

VI. Daily protective measures

1. Regular cleaning: Regular cleaning of the aluminum housing can remove dirt and impurities on the surface and prevent them from damaging the appearance. You can use a soft cloth or sponge with clean water or a mild detergent to gently wipe the surface of the housing.
2. Avoid contact with corrosive substances: If the aluminum housing comes into contact with corrosive substances such as acid, alkali, salt, etc., it will damage the appearance. Therefore, when using the aluminum housing, you should avoid contact with these substances.
3. Control temperature: Too high or too low temperature will damage the appearance of the aluminum housing. Avoid exposing the aluminum housing to extreme temperature conditions, or preheat or cool it before use.
4. Avoid collision and extrusion: The aluminum housing will be deformed or damaged if it is subjected to collision and extrusion. The aluminum housing should be placed away from places that are prone to extrusion and collision, or necessary protective measures should be taken during transportation and storage.
5. Regular maintenance: Regular maintenance of the aluminum casing, such as painting, polishing, grinding, etc., can maintain its beautiful appearance and integrity.
