Process flow and raw materials of aluminum and aluminum alloy anodic oxidation tintingProcedure specification on aluminum and aluminum alloy anodic oxidation tinting1. Procedure specification(line drawing)Substrate → Mounted hanging → Degreasing → Alkaline etching → Neutralization → Anodic oxidation → Electrolytic coloring → Sealing → Electrophoretic coating → Curing → Unloading packaging → Warehousing2. Mounted hanging:2.1 preparations before mounted hanging. Check the conductive parts like conductive beams and bars. They should be regularly polished, cleaned or repaired. Get ready conductivity of aluminum and aluminum wire. Check the pneumatic tools and related equipment. 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. 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. 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: 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. 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. When hanging, it is not allowed to hang all the materials in the lower or upper rack. The hanged materials should recline more than 14 degrees in order to facilitate air exhausting in electrophoresis or coloring, and reduce the air bubbles. When hanging, considering the facing of the decorative surface and groove to prevent the color shading, bubbles, pitting appearing in the decorative surface. Like some flexible and easily deformed materials, put one more rack or aluminum wire in the middle to prevent friction between the materials or touching tank plate, and that may abrade or burn the surface. When selecting vice-bar rack, the plug rod is preferred. When using aluminum banding, they must be evenly spaced, and the outcrops should be less than 25mm. Materials with great disparity of cross-section size and shape are prohibited to hang in the same row. When hanging and handling equipment, you must wear clean gloves, gently and well protecting the surface. When hanging or handling equipment, workers should strengthen self-examination and cross-examination, the failure materials are non-mounted, and take appropriate measures to deal with the surface stained with oil or aluminum burrs After eliminating unqualified ones, you must make them up in time by order.2.2.12 In hanging area, materials should not be stored for too long time, to prevent corrosion of the surface. Filling the hanging record and oxidation process card. Accurately calculating and fill in oxidation of each linked area, checking models, count and color by orders at any time. Do a good job in shift procedures and keep the work area clean.3. Preparation before oxidized production units:3.1 Checking the level of the liquid in the process tank. According to test report card, to adjust the concentration of the bath solution and ensure that bath solution is always in line with technical requirements. Workers should frequently sweep the dirt from the bath solution.3.2 Checking the vehicle, freezer, rectifiers, circulating acid pump, water pump, transfer cars, furnace and other equipment, any exception should be immediately solved.3.3 Check PH (or conductivity) and cleanliness in the pure water washing tank and running water washing tank. If it does not meet the technical requirements, workers should change it and hydrating overflow.3.4 Open the alkaline etching, hot pure water tank, sealing the steam or cooling water tank; open the oxidation tank, coloring tank and cooling system of electrophoresis tank to ensure the uniformity of bath solution and temperature complying with requirements.3.5 Check the Roots blowers, exhaust blowers and exhaust fans. Before the production, they should be opened.3.6 Carefully check the oxidation process card, specifically confirm the production requirements, and prepare the color palette.4. General requirements for oxidation sets operation:4.1 It is not allowed to hang t more than two hangings every time. And keeping a certain distance between the two hangings to prevent collision between the materials.4.2 When materials hung into and hung out of the bath solution, they must be inclined to 30°.4.3 Materials falling into the tank must be removed promptly and hung up in rafts, the damage ones must be promptly notified to group-to-order equipment to make th。
