當一輛奔馳車輛進入維修車間，技師首先會進行全方位的劃痕評估。借助專業色差儀和漆膜測厚儀，對損傷區域進行精準檢測。對于輕微劃痕，技師會采用局部修復方案，通過干磨機搭配P1200號砂紙進行精細打磨，確保表面平滑度。若劃痕觸及底漆，則需啟動整套噴漆流程，使用紅外線烤燈對損傷部位進行預加熱，提升金屬板件的附著性。

　　When a Mercedes Benz vehicle enters the repair workshop, the technician will first conduct a comprehensive scratch assessment. With the help of professional colorimeters and paint film thickness gauges, precise detection of damaged areas can be carried out. For minor scratches, technicians will adopt a local repair plan, using a dry grinder combined with P1200 grit sandpaper for fine polishing to ensure surface smoothness. If the scratch touches the primer, the entire painting process needs to be initiated, using an infrared baking lamp to preheat the damaged area and improve the adhesion of the metal plate.

　　表面處理環節堪稱工藝核心。技師會使用進口干磨系統，配備集塵裝置，確保作業環境清潔。針對不同材質的保險杠或車身面板，采用差異化的打磨策略。對于鋁合金部件，需使用專用砂紙避免金屬氧化。在底漆施工階段，選用奔馳原廠認證的環氧底漆，通過高壓無氣噴涂設備，實現0.05毫米的漆膜厚度控制，確保防腐性能與層間附著力。

　　The surface treatment process can be regarded as the core of the technology. Technicians will use imported dry grinding systems equipped with dust collection devices to ensure a clean working environment. Adopt differentiated polishing strategies for bumpers or body panels made of different materials. For aluminum alloy components, specialized sandpaper should be used to prevent metal oxidation. During the primer construction stage, Mercedes Benz certified epoxy primer is selected, and a high-pressure airless spraying equipment is used to achieve a film thickness control of 0.05 millimeters, ensuring anti-corrosion performance and interlayer adhesion.

　　面漆噴涂工藝體現著技術精髓。維修車間配備恒溫恒濕噴漆房，溫度控制在22℃±2℃，濕度維持55%±5%。技師根據車輛VIN碼調取原廠色號數據，使用進口光譜儀進行三次色差校準。噴涂過程采用三遍噴涂法：首遍霧噴控制流平，二遍勻噴建立漆膜，三遍清漆提升光澤度。每層噴涂間隔嚴格控制在10分鐘，確保溶劑充分揮發。

　　The topcoat spraying process embodies the essence of technology. The maintenance workshop is equipped with a constant temperature and humidity spray painting room, with a temperature controlled at 22 ℃± 2 ℃ and a humidity maintained at 55% ± 5%. The technician retrieves the original color code data based on the vehicle VIN code and performs three color difference calibrations using an imported spectrometer. The spraying process adopts a three-layer spraying method: the first layer of mist spraying controls leveling, the second layer of uniform spraying establishes a paint film, and the third layer of clear varnish enhances glossiness. The spraying interval for each layer is strictly controlled at 10 minutes to ensure that the solvent evaporates fully.

　　烘烤固化環節采用紅外線與熱風對流復合工藝。首段60℃保持15分鐘激活固化劑，二段80℃持續20分鐘完成交聯反應，最終通過自然冷卻避免漆膜應力。拋光處理則使用進口拋光機，搭配3D立體拋光墊，從粗蠟到細蠟進行三階段處理，最終實現鏡面效果。

　　The baking and curing process adopts a composite technology of infrared and hot air convection. The curing agent is activated in the first stage at 60 ℃ for 15 minutes, and the crosslinking reaction is completed in the second stage at 80 ℃ for 20 minutes. Finally, the coating stress is avoided by natural cooling. The polishing process uses an imported polishing machine, paired with a 3D three-dimensional polishing pad, and undergoes three-stage processing from coarse wax to fine wax, ultimately achieving a mirror effect.

　　質量控制貫穿整個工藝流程。技師會使用漆膜儀進行多點檢測，確保漆面厚度符合原廠120-150微米標準。在色差檢驗環節，采用D65標準光源對色箱，從15°、45°、75°三個角度進行比對。最終驗收包含漆面硬度測試、耐候性模擬等七項檢測，確保修復部位與原廠漆面達到95%以上的匹配度。

　　Quality control runs through the entire process flow. Technicians will use a paint film gauge for multi-point testing to ensure that the paint thickness meets the original factory standard of 120-150 microns. In the color difference inspection stage, D65 standard light source is used to compare the color box from three angles of 15 °, 45 °, and 75 °. The final acceptance includes seven tests, including paint hardness testing and weather resistance simulation, to ensure that the repaired area matches the original paint surface by more than 95%.

　　這項工藝的精妙之處，在于將現代科技與傳統匠藝深度融合。從精準的漆面數據管理，到智能化的環境控制系統，再到嚴苛的質檢流程，每個細節都彰顯著對品質的執著追求。在濟南的汽車維修行業，這種對工藝的極致把控，正不斷刷新著豪華車維修服務的標準。

　　The subtlety of this craftsmanship lies in the deep integration of modern technology and traditional craftsmanship. From precise paint data management, to intelligent environmental control systems, to rigorous quality inspection processes, every detail demonstrates a persistent pursuit of quality. In the automotive repair industry in Jinan, this extreme control over craftsmanship is constantly refreshing the standards of luxury car repair services.
