5052鋁板的電解著色具有良好的裝飾效果，因此在國(guó)內(nèi)外得到了廣泛的應(yīng)用，特別是在建筑鋁型材的表面處理方面。目前，主要工藝是采用錫鎳混合鹽電解著色，產(chǎn)品顏色主要是香檳色，相比于單一的鎳鹽著色，錫鎳混合鹽電解著色產(chǎn)品顏色鮮亮、飽滿;主要問題是產(chǎn)品色差，鋁板生產(chǎn)廠家鋁型材擠壓工藝和氧化著色工藝在生產(chǎn)過程中會(huì)導(dǎo)致產(chǎn)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.

　　擠壓工藝對(duì)氧化著色的影響主要是模具設(shè)計(jì)、擠壓溫度、擠壓速度和冷卻方式對(duì)擠壓型材表面狀態(tài)和微觀組織均勻性的影響。模具設(shè)計(jì)時(shí)應(yīng)能使進(jìn)料充分揉捏，否則容易出現(xiàn)明(暗)帶缺陷，同一段可能出現(xiàn)色差;同時(shí)，模具狀態(tài)和型材表面的擠出線也會(huì)影響型材的氧化著色。
　　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.
　　擠出溫度、速度、冷卻方式和冷卻時(shí)間不同，使型材組織不均勻，也會(huì)產(chǎn)生色差。陽(yáng)極氧化電解著色色差的有著重要的影響,特別是在垂直氧化生產(chǎn)線的過程中很容易出現(xiàn)的兩個(gè)顏色,立式氧化溝的深度7.5米,浴和容易產(chǎn)生溫差,溫度對(duì)陽(yáng)極氧化具有重要影響,高溫、液體氧化槽提高氧化膜的溶解,多槽表面的陽(yáng)極氧化膜孔徑的增加,相反，陽(yáng)極氧化膜表面的許多溝槽孔徑較小。此外，高溫會(huì)導(dǎo)致陽(yáng)極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.
　　電解著色主要是使著色液態(tài)金屬的離子在氧化膜表面的微孔阻擋層電化學(xué)還原反應(yīng),使有色液體沉積金屬離子對(duì)陽(yáng)極氧化膜孔的底部的入射光散射和顯示不同的顏色,沉積的微孔材料,越多,顏色越深。在相同的電量條件下，在高溫和低溫部位沉積相同數(shù)量的金屬或金屬化合物。對(duì)于孔隙率高、表面孔徑大的部位，平均每個(gè)孔的含沙量較小。
　　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鋁板的顏色相對(duì)較淺，而顏色相對(duì)較深，導(dǎo)致上色材料兩端的顏色。5052鋁板陽(yáng)極氧化過程中,氧化膜的電導(dǎo)率,也會(huì)導(dǎo)致顏色材料產(chǎn)生色差,主要問題是在水平線很容易出現(xiàn),主要是由于氧化氧化過程的前面的空白,夾不緊,導(dǎo)致不良個(gè)人導(dǎo)電材料,使其相對(duì)不同的氧化膜,染色后會(huì)產(chǎn)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.
