機箱機柜外殼上色是保障設備外觀與使用壽命的重要環節，需遵循規范流程以確保涂層均勻、附著牢固。以下為具體步驟解析：
Coloring the chassis and cabinet shell is an important step in ensuring the appearance and service life of equipment, and it is necessary to follow standardized procedures to ensure uniform coating and firm adhesion. Here are the specific steps for analysis:
前期表面處理是基礎。先以高壓氣槍浮塵，再用中性清潔劑擦拭，清理焊接處與縫隙的油污、銹跡及碎屑，清水沖洗后晾干。對有毛刺、劃痕的表面，用砂紙從粗到細打磨平整，增強涂層附著力。金屬外殼需經酸洗或噴砂除銹，之后涂底漆防二次生銹。
Pre surface treatment is the foundation. First, use a high-pressure air gun to remove floating dust, then wipe with a neutral cleaning agent, focusing on cleaning the oil stains, rust, and debris at the welding joints and gaps. Rinse with clean water and air dry. For surfaces with burrs and scratches, use sandpaper to polish from coarse to fine until smooth, enhancing the adhesion of the coating. The metal casing needs to be pickled or sandblasted to remove rust, and then coated with primer to prevent secondary rusting.
涂裝前需做好準備。依據使用環境選合適涂料，如防銹漆、靜電粉末涂料等，確認顏色與配比后，按比例調配并攪拌均勻，避免沉淀。準備噴槍、刮刀等工具，確保清潔完好。對接口、銘牌等無需上色部位，用膠帶或遮蔽紙遮蓋。
Preparation is required before painting. Select suitable coatings based on the usage environment, such as rust proof paint, electrostatic powder coating, etc. After confirming the color and ratio, mix and stir evenly according to the ratio to avoid sedimentation. Prepare spray guns, scrapers, and other tools to ensure cleanliness and integrity. Cover non colored parts such as interfaces and nameplates with tape or masking paper.
正式上色時，若用噴涂，調整噴槍壓力與噴嘴，保持 20-30 厘米距離，勻速噴涂使涂層均勻，避免流掛、漏噴，按先橫后縱順序分多次進行，待前層干燥再噴下一層。刷涂則用軟毛刷沿同一方向操作，注意邊角、凹槽的覆蓋。
When officially coloring, if spraying is used, adjust the pressure of the spray gun and nozzle, maintain a distance of 20-30 centimeters, and spray at a constant speed to make the coating uniform, avoiding sagging and leakage. Repeat the process in a horizontal to vertical sequence, and wait for the previous layer to dry before spraying the next layer. When brushing, use a soft bristled brush to operate in the same direction, paying attention to the coverage of corners and grooves.
上色后進入干燥固化階段。將工件放在通風處，依涂料類型控制溫濕度。自然干燥需保證環境潔凈，烘烤干燥嚴格按說明控制烤箱溫度，避免高溫導致涂料變色開裂，過程中防止碰撞震動。
After coloring, it enters the drying and curing stage. Place the workpiece in a ventilated area and control the temperature and humidity according to the type of coating. Natural drying requires a clean environment, and baking and drying should strictly control the oven temperature according to the instructions to avoid discoloration and cracking of the coating caused by high temperatures. During the process, collision and vibration should be prevented.
進行后期檢查與修整。涂層干透后移除遮蔽物，檢查是否有氣泡、針孔、色差等問題。小面積瑕疵可打磨后補涂，大面積問題需涂層重涂。完成后擦拭表面，確保上色效果達標。
Finally, conduct post inspection and repair. After the coating is dry, remove the cover and check for any bubbles, pinholes, color differences, and other issues. Small area defects can be polished and repainted, while large area problems require removal and repainting of the coating. After completion, wipe the surface to ensure that the coloring effect meets the standard.
整個流程需嚴控各環節質量，以保證外殼既美觀，又能抵御環境侵蝕，延長設備使用壽命。
The entire process needs to strictly control the quality of each link to ensure that the shell is both aesthetically pleasing and resistant to environmental erosion, thereby extending the service life of the equipment.
