If the actual effect of the color of the aluminum double plate cannot exceed the estimated actual effect, it will cause great harm to its application. What are the chromatic aberrations affecting the surface of 6A02 aluminum plate products during manufacturing?

1. The temperature of the dyeing solution.

The dyeing of 6A02 aluminum plate products is divided into cold dyeing and hot dyeing. Cold dyeing is used for a long time in the processing process and has a good grasp of color uniformity. Heat dyeing has a shorter application time, but there is no way to control the color. Heat dyeing temperature is generally 40 ℃ 60 ℃. If the temperature is too high, it will reduce the adsorption of dyeing, and it is very easy to make the surface of 6A02 aluminum plate products bloom.

2. The harm of air oxide film to the quality of aluminum veneer.

Air oxide film refers to the thickness, porosity and clarity of 6A02 aluminum plate products. The thickness of the air oxide film in 6A02 aluminum plate products can be maintained at about 10μm, which can obtain porosity and clarity, and can achieve better dyeing quality.

3. Concentration of staining solution. The concentration of the staining solution is related to the staining. After the aluminum veneer is colored, the concentration is lower, and the light color concentration is slightly higher. If the dye concentration is high, it will cause uneven color or wave color, which is very easy to appear in the whole process of cleaning and turning off the 'fluid color'. In order to improve the ability of the dye to absorb the dye, a low concentration of color is used to increase the dyeing, so that the molecular structure of the dye can penetrate into the pores of the air oxidation film more evenly, so that the color is more harmonious and firm.

4.6A02 Hazards of raw materials of aluminum plate products parts. Under normal circumstances, high-purity aluminum, aluminum-magnesium, and aluminum-manganese-aluminum alloys have better dyeing properties after oxidation treatment, and can be dyed into a variety of colors. For boards that are heavy on silicon or copper, only dark brown and gray-black are dyed in the whole dyeing process, and the color is simpler.
