5052铝板的电解着色具有良好的装饰效果，因此在国内外得到了广泛的应用，特别是在建筑铝型材的表面处理方面。目前，主要工艺是采用锡镍混合盐电解着色，产品颜色主要是香槟色，相比于单一的镍盐着色，锡镍混合盐电解着色产品颜色鲜亮、饱满;主要问题是产品色差，铝板生产厂家铝型材挤压工艺和氧化着色工艺在生产过程中会导致产品色差。
　　The electrolytic coloring of 5052 aluminum plate has a good decorative effect, so it has been widely used at home and abroad, especially in the surface treatment of building aluminum profiles. At present, the main process is electrolytic coloring with tin nickel mixed salt, and the product color is mainly champagne color. Compared with single nickel salt coloring, the product color of electrolytic coloring with tin nickel mixed salt is bright and full; the main problem is product color difference, which will be caused by aluminum extrusion process and oxidation coloring process of aluminum plate manufacturer in the production process.

　　挤压工艺对氧化着色的影响主要是模具设计、挤压温度、挤压速度和冷却方式对挤压型材表面状态和微观组织均匀性的影响。模具设计时应能使进料充分揉捏，否则容易出现明(暗)带缺陷，同一段可能出现色差;同时，模具状态和型材表面的挤出线也会影响型材的氧化着色。
　　The influence of extrusion process on oxide coloring is mainly the influence of die design, extrusion temperature, extrusion speed and cooling mode on the surface state and microstructure uniformity of extruded profiles. In the design of the die, the feed should be kneaded sufficiently, otherwise the bright (dark) band defects will appear easily, and the color difference may appear in the same section; at the same time, the die state and extrusion line on the surface of the profile will also affect the oxidation coloring of the profile.
　　挤出温度、速度、冷却方式和冷却时间不同，使型材组织不均匀，也会产生色差。阳极氧化电解着色色差的有着重要的影响,特别是在垂直氧化生产线的过程中很容易出现的两个颜色,立式氧化沟的深度7.5米,浴和容易产生温差,温度对阳极氧化具有重要影响,高温、液体氧化槽提高氧化膜的溶解,多槽表面的阳极氧化膜孔径的增加,相反，阳极氧化膜表面的许多沟槽孔径较小。此外，高温会导致阳极氧化膜的孔隙率增大，反之亦然。
　　Different extrusion temperature, speed, cooling mode and cooling time make the structure of profile uneven, and also produce color difference. The color difference of anodizing electrolytic coloring has an important influence, especially the two colors that are easy to appear in the process of vertical oxidation production line. The depth of vertical oxidation ditch is 7.5m, and the temperature difference between bath and bath is easy to occur. Temperature has an important influence on anodizing. High temperature and liquid oxidation tank improve the dissolution of oxidation film, and the pore diameter of anodizing film on the surface of multiple tanks increases. On the contrary, the surface of anodizing film Many grooves on the surface have smaller apertures. In addition, high temperature will increase the porosity of anodized film, and vice versa.
　　电解着色主要是使着色液态金属的离子在氧化膜表面的微孔阻挡层电化学还原反应,使有色液体沉积金属离子对阳极氧化膜孔的底部的入射光散射和显示不同的颜色,沉积的微孔材料,越多,颜色越深。在相同的电量条件下，在高温和低温部位沉积相同数量的金属或金属化合物。对于孔隙率高、表面孔径大的部位，平均每个孔的含沙量较小。
　　Electrolytic coloring is mainly to make the colored liquid metal ions in the microporous barrier on the surface of the oxide film electrochemical reduction reaction, so that the nonferrous liquid deposition metal ions on the bottom of the anode oxide film hole incident light scattering and display different colors, the more microporous materials deposited, the deeper the color. Under the same electricity condition, the same amount of metals or metal compounds are deposited at high and low temperature. For the parts with high porosity and large surface aperture, the average sediment concentration of each pore is small.
　　因此，5052铝板的颜色相对较浅，而颜色相对较深，导致上色材料两端的颜色。5052铝板阳极氧化过程中,氧化膜的电导率,也会导致颜色材料产生色差,主要问题是在水平线很容易出现,主要是由于氧化氧化过程的前面的空白,夹不紧,导致不良个人导电材料,使其相对不同的氧化膜,染色后会产生色差。
　　Therefore, the color of 5052 aluminum plate is relatively light, while the color is relatively dark, resulting in the color of both ends of the colored material. In the anodizing process of 5052 aluminum plate, the conductivity of the oxide film will also cause color difference of the color material. The main problem is that it is easy to appear on the horizontal line, mainly because the blank in front of the anodizing process is not tightly clamped, resulting in poor personal conductive material, making its relatively different oxide film, which will produce color difference after dyeing.
