The surface treatment of aluminum ceiling is coating, roller coating, and anodic oxidation. The several technical methods and advantages of the implementation are not identical respectively. Coating is kinds of physical technology, forming by pressing a layer of film and a layer of aluminum plate after high temperature and high pressure. Roller coating is to use the initial character of three of hot rolled high-quality aluminum alloy plate in the international standard as base material. It is formed through the processing technology of three times coating baking and three times roller coating. Anodic oxidation regards metal or alloy parts as anode, and it is adopted electrolytic method to make the surface take shape oxide thin film.
(a) Coating.
Advantages of Coating technology are
1. Anti-smoke: the coating is processed by PVC and is convenient to clean.
2. High wear resistance: special PET layer, strong and durable.
3. Characteristic of moisture proof: coated on the surface, avoid touching directly water with aluminum products, strong durability.
4. Good touch: the coating surface has a layer of skim. Smooth touch changes the single feeling to metal materials.
5. Various colors: a variety of colors to choose from.
6. Moderate price and good cost performance.
(b) Roller coating.
1. Healthy and environmental protection: it adopts international standard aluminum products as the base material without chromium under free condition and other harmful metallic elements. It meets the international standards of the European Union.
2. Adopt the advanced nanotechnology, resistance to corrosion and oil prevention.
3. Resistant to decay: durable color and change color uneasily.
4. Resistant to acid and alkali.
5. Resistance to pulverization: uniform and fine roller coating technology and effectively avoid pulverization phenomenon of the suspended ceiling surface.
(c) Anodic oxidation.
Advantages of anodic oxidation technology are
1. Healthy and environmental protection: no chromium, mercury, cadmium and other harmful metal elements.
2. Scratch and wear resistant: it can achieve the sapphire hardness.
3. Anti-fingerprints.
4. Anticorrosion
5. Self-cleaning: antistatic, absorb dust uneasily and clean up easily.
6. Colorful: treated after many anodic oxidation, rich color, and true BI colors.
7. Fine workmanship board: work with great care by 36 kinds of technology, and the concave and convex texture on the surface can effectively shield the radiation.
