[China Aluminum Industry Network] The surface treatment of aluminum ceilings mainly includes coating, rolling, and anodizing. Each method has its own unique implementation process and advantages. Film lamination is a physical process where a layer of film is applied to the aluminum sheet using high temperature and pressure. Roller coating involves the use of high-quality aluminum alloy plates that are coated with multiple layers through a three-roll system. Anodizing, on the other hand, is an electrochemical process in which an oxide layer is formed on the metal surface by acting as an anode in an electrolytic solution.
(1) Film Lamination: This is a physical process where a protective film is bonded to the aluminum sheet under high temperature and pressure. Its key benefits include:
1. Oil and Smoke Resistance: Made from PVC high-gloss film, it is easy to clean and maintain.
2. Wear Resistance: The inclusion of a PET layer makes it durable and long-lasting.
3. Moisture Resistance: The surface coating prevents direct contact between water and the aluminum, enhancing durability.
4. Comfortable Feel: The film provides a smooth, warm touch, reducing the cold sensation typically associated with metal.
5. Color Variety: A wide range of colors are available to suit different design preferences.
6. Cost-Effective: Offers good value for money while maintaining quality.
(2) Roller Coating: This technique uses international standard aluminum materials—specifically hot-rolled high-quality aluminum alloy plates. It involves a three-coat, three-roll coating process. Key advantages include:
1. Health and Environmental Friendly: Uses aluminum that is free from harmful elements like chromium and lead, meeting EU standards.
2. Advanced Nanotechnology: Provides scratch resistance, oil resistance, and corrosion protection.
3. Long-Lasting Color: Resists fading and maintains vibrant color over time.
4. Acid and Alkali Resistance: Suitable for various environments.
5. Dust-Free Finish: The uniform coating minimizes powdering on the ceiling surface.
(3) Anodizing: This electrochemical process creates a durable oxide layer on the aluminum surface. Its advantages are:
1. Eco-Friendly: Free from harmful metals like mercury, cadmium, and lead.
2. Hardness: Achieves sapphire-like hardness, making it highly resistant to scratches and wear.
3. Anti-Fingerprint: Reduces visible smudges and fingerprints.
4. Corrosion Resistance: Offers excellent protection against rust and degradation.
5. Self-Cleaning: Anti-static properties prevent dust accumulation, making cleaning easier.
6. Rich Colors: Produces vibrant, true-to-life colors that enhance aesthetics.
7. Radiation Shielding: Some advanced anodized surfaces feature a textured finish that helps shield radiation.
