Coloring Process of Aluminum Honeycomb Panel

Anodic oxidation coloring process

aluminum honeycomb panelThe fresh oxide film obtained by anodic oxidation blowing has a strong adsorption capacity and can be treated with a variety of bright colors, which can beautify the surface of aluminum Products and increase the corrosion resistance of the oxide film.

根据着色物质和色素在氧化膜中分布的不同，可分为自然发色发、电解着色法和染色法三类。其中自然发色法是在anodic oxidation电解的同时，使得氧化膜获得了颜色;Coloring and dyeing is done after the anodic oxide film is prepared.

surface plating

By the surface plating, the surface corrosion resistance and the surface decoration of the aluminum alloy material can be improved. Since aluminum is a typical amphoteric metal, it will react violently when encountering acid and alkali, which makes electroplating on aluminum parts much more difficult than plating on steel substrates and requires some special treatment. Compared with anodic oxidation coloring, electroplating aluminum alloy has very limited coating color. Electroplating is generally copper-nickel-chromium plating, wear-resistant, anti-corrosion, and electroplating will be selected for general automobiles, sanitary ware, lighting, furniture, etc. At present, the cost of electroplating surface decoration is relatively high.

Aluminum alloy surface decorative electroplating processing mainly uses polished electrolytic oxidation coloring copper, nickel, chromium, other decorative coatings such as imitation gold.

coating process

辊涂是一种油漆涂覆工艺,is through a rubber roller or steel roller,Apply paint to aluminum plate surface.The coating is leveled and arranged, and finally uniformly transferred to the moving steel belt for curing, thus coating the steel molecular organic solid protective film.
