  电解着色的合金铝板生产厂家具有良好的装饰性能,因此在国内外得到广泛应用,尤其在建筑铝型材的表面处理生产中。目前,主要工艺是采用锡-镍混合盐电解着色,产品颜色以香槟色为主,与单镍盐着色相比,锡-镍混合盐电解着色产品颜色鲜艳、饱满;主要问题是产品存在色差。铝型材生产过程中不合理的挤压工艺和氧化着色工艺会导致产品色差。
  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.

  挤压工艺对合金铝板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。模具设计应能使进料充分滚动,否则容易出现亮(暗)带缺陷,同一型材上可能出现分离;同时,模具状态和型材表面的挤压颗粒也会影响型材的氧化着色。挤出温度、速度、冷却方式和冷却时间等,使型材不均匀,也会产生色差。
  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.
  铝板生产厂家的阳极氧化铝合金电解着色色差有非常重要的影响,特别是在垂直氧化生产线的过程很容易出现两种颜色,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,阳极氧化膜表面的沟槽越多,孔径越大,相反,阳极氧化膜表面的沟槽越多,孔径越小。此外,阳极氧化膜的孔隙率在温度高时较高,在温度低时较低。
  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.
  合金铝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,相同数量的金属或金属化合物沉积在高温和低温部位。对于孔隙率高、表面孔径大的部位,每个孔的平均含沙量较小。因此,5052铝板的颜色比较浅,而颜色较深,导致上色材料的两端都有颜色。合金铝制造商在阳极氧化过程中,氧化膜的电导率,也会导致材料产生色差,颜色问题是主要的水平线是容易的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。
  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.
