Aluminum honeycomb panel surface treatment process is as follows

aluminum honeycomb panelIt is a composite material with large surface formed by hot pressing of high-grade aluminum alloy panel, back plate and aluminum honeycomb core material. The product specifications are various, and the surface can be embossed, mirror, embossed, wire drawing, electroplating, anodizing, matte, bright light and metallic color, etc., which can meet the application requirements of various places.

Surface treatment technology through some physical and chemical means to give the surface of the material with special properties to meet the various requirements of the material, all these changes in the physical and chemical properties of the material surface processing technology is collectively referred to as surface treatment or surface processing.

Texture Process of 1. Surface Etching

金属蚀刻(etching)It is a technology in which materials are removed by chemical reaction or physical impact.

Aluminum alloy etching decoration through the surface of the material corrosion out of concave-convex three-dimensional sense of decorative patterns or text, can be flexible to show the height of different bending or radian. Not easy deformation is very suitable for personalized product engraving printing processing.

2. Surface Finishing Texture Technology

1Polishing is to get a smooth surface or mirror gloss for the purpose, and sometimes to eliminate gloss(Extinction). Polished aluminum has excellent reflectivity over a wide range of wavelengths, and thus has a variety of decorative applications and applications with reflective functionality. Its natural surface state has a pleasant appearance. It is soft, shiny, and can be colored or dyed with textured patterns for aesthetics.

2Sand blasting

In the nameplate of aluminum alloy material, sandblasting is often used for surface treatment. Sandblasting on the surface of aluminum alloy materials will get a relatively soft surface finish and roughness, and obtain a film light decoration or a surface effect with a fine reflective surface, which is often used as a background decoration for embossed graphics.

3Wire drawing

The aluminum alloy wire drawing process can clearly show each fine wire mark, so that the aluminum alloy can give a fine hair luster in the matte, and the product has both fashion and technology. The common aluminum alloy surface drawing effect can be divided into straight wire drawing, random wire drawing and rotating wire drawing.

4Embossing

The required texture is obtained on the surface of the aluminum alloy material product by the pressing process.

3. anodic oxidation coloring process

Aluminum and its alloys after anodic oxidation blowing and the fresh oxide film has a strong adsorption capacity, can be treated by a certain process to make it with a variety of bright colors, which can beautify the surface of aluminum Products, but also 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.

4. 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.

5. 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.
