Process flow and raw materials of aluminum and aluminum alloy anodic oxidation tinting Procedure specification on aluminum and aluminum alloy anodic oxidation tinting Procedure specification(line drawing) Substrate → Mounted hanging → Degreasing → Alkaline etching → Neutralization → Anodic oxidation → Electrolytic coloring → Sealing → Electrophoretic coating → Curing → Unloading packaging → Warehousing 2. Mounted hanging: 2.1 preparations before mounted hanging. 2.1.1 Check the conductive parts like conductive beams and bars. They should be regularly polished, cleaned or repaired. 2.1.2 Get ready conductivity of aluminum and aluminum wire. 2.1.3 Check the pneumatic tools and related equipment. 2.1.4 Check whether or not requirements like length, count, color, thickness on the flow paper or production task list are consistent with the order drawing and actual materials. 2.1.5 Depending on the specifications (size of circumscribed circle, external surface area, etc.) to determine the count and space. To control the pigment spacing about 1.2 times than the horizontal width of the material shaped, and the white material spacing about 1 time than the width. 2.1.6 Choose the appropriate rack, and ensure that hook number of negative and positive hangers is the same with the count of materials shaped. 2.2 Mounted hanging: 2.2.1 When hanging, fix the topside one first, and then the bottom one, and then arrange the remaining sections in the middle, and tighten the screws. 2.2.2 Before hanging, placing one aluminum sheet between the material and aluminum screw p so that it can prevent poor conductivity impacting oxidation, coloring and electrophoresis. 2.2.3 When hanging, it is not allowed to hang all the materials in the lower or upper rack. 2.2.4 The hanged materials should recline more than 14 degrees in order to facilitate air exhausting in electrophoresis or coloring, and reduce the air bubbles. 2.2.5 When hanging, considering the facing of the decorative surface and gro
