電解著色的合金鋁板生產廠家具有良好的裝飾性能,因此在國內外得到廣泛應用,尤其在建筑鋁型材的表面處理生產中。目前,主要工藝是采用錫-鎳混合鹽電解著色,產品顏色以香檳色為主,與單鎳鹽著色相比,錫-鎳混合鹽電解著色產品顏色鮮艷、飽滿;主要問題是產品存在色差。鋁型材生產過程中不合理的擠壓工藝和氧化著色工藝會導致產品色差。
The furniture of electrolytic coloring aluminum alloy plate factory has good decorative performance, so it is widely used at home and abroad, especially in the surface treatment of building aluminum profiles. At present, the main process is electrolytic coloring of tin nickel mixed salt. The product color is mainly champagne. Compared with single nickel salt, the electrolytic coloring of tin nickel mixed salt is bright and full. The main problem is that the product has color difference. In the production process of aluminum profile, unreasonable extrusion technology and oxidation coloring technology will lead to product color difference.
擠壓工藝對合金鋁板氧化著色的影響主要是模具設計、擠壓溫度、擠壓速度和冷卻方式對擠壓型材表面狀態和微觀組織均勻性的影響。模具設計應能使進料充分滾動,否則容易出現亮(暗)帶缺陷,同一型材上可能出現分離;同時,模具狀態和型材表面的擠壓顆粒也會影響型材的氧化著色。擠出溫度、速度、冷卻方式和冷卻時間等,使型材不均勻,也會產生色差。
The influence of extrusion process on the oxidation coloring of aluminum alloy plate is mainly the influence of die design, extrusion temperature, extrusion speed and cooling mode on the surface state and microstructure uniformity of extruded profiles. The die design shall be able to fully roll the feed, otherwise bright (dark) band defects may occur easily, and separation may occur on the same profile; at the same time, the die state and extruded particles on the profile surface will also affect the oxidation coloring of the profile. Extrusion temperature, speed, cooling mode and cooling time, etc., make the profile uneven, and also produce color difference.
鋁板生產廠家的陽極氧化鋁合金電解著色色差有非常重要的影響,特別是在垂直氧化生產線的過程很容易出現兩種顏色,立式氧化溝的深度7.5米,浴和容易產生溫差,溫度對陽極氧化具有重要影響,高溫、液體氧化槽提高氧化膜的溶解,陽極氧化膜表面的溝槽越多,孔徑越大,相反,陽極氧化膜表面的溝槽越多,孔徑越小。此外,陽極氧化膜的孔隙率在溫度高時較高,在溫度低時較低。
The color difference of anodized aluminum alloy electrolytic coloring of aluminum plate manufacturers has a very important influence, especially in the process of vertical oxidation production line, two colors are easy to appear, the depth of vertical oxidation ditch is 7.5m, the temperature difference between bath and anodizing is easy to occur, the temperature has an important impact on anodizing, high temperature and liquid oxidation tank improve the dissolution of oxide film, On the contrary, the more grooves on the surface of anodized film, the smaller the pore size. In addition, the porosity of anodized film is higher at high temperature and lower at low temperature.
合金鋁電解著色主要是使著色液態金屬的離子在氧化膜表面的微孔阻擋層電化學還原反應,使有色液體沉積金屬離子對陽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,相同數量的金屬或金屬化合物沉積在高溫和低溫部位。對于孔隙率高、表面孔徑大的部位,每個孔的平均含沙量較小。因此,5052鋁板的顏色比較淺,而顏色較深,導致上色材料的兩端都有顏色。合金鋁制造商在陽極氧化過程中,氧化膜的電導率,也會導致材料產生色差,顏色問題是主要的水平線是容易的出現主要是由于氧化氧化過程的前面的空白,夾不緊,導致不良個人導電材料,使其相對不同的氧化膜,染色后會產生色差。
Electrolytic colouring of aluminum alloy is mainly to make the ions of colored liquid metal react with electrochemical reduction in the microporous barrier layer on the surface of the oxide film, which makes the incident light scattering and display different colors on the bottom of the anode oxide film hole by the metal ions deposited in the nonferrous liquid. The more microporous materials are deposited, the deeper the color is. 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. Therefore, the color of 5052 aluminum plate is lighter and darker, resulting in color on both ends of the colored material. In the anodizing process of aluminum alloy manufacturers, the conductivity of oxide film will also lead to color difference of materials. The color problem is that the main horizontal line is easy to appear, mainly because the blank in front of the oxidation process is not tightly clamped, resulting in poor personal conductive materials, making its relatively different oxide film, which will produce color difference after dyeing.
