Type A: only a slight of paint striping at the inside of the hook.B类：指工件外表面均合格，只是局部死角内部难以喷涂到，局部少漆的零件Type B: Workpiece whose surface is qualified, with partial dead corners hard to paint and partial paint removal.C类：指工件外表面局部地区（面积≤50cm2）有少漆、挂漆、颗粒、杂质、气泡、针孔、划伤、电花、鱼眼等喷涂缺陷的零件Type C: There are following deficencies with partial outside surface of workpiece(area≤50cm):paint removal, paint hanging, particular, impurities, bubble, pinhole, gash, flower power, fisheye, etc.D类：指膜厚整体超高或偏低，外观大面积缺陷或缺陷在A级面上的零件以及在功能上有严重缺陷的零件（备注：功能缺陷是指附着力、色差、光泽等严重不达标）。

Type D: The overall thickness is too high or low. There is large-area visual deficency or the deficency comes to level A. There are serious functional deficencies. (functional deficencies: serious problems with adhension, chromatism, gloss)5.3 修补/Repair5.3.1 A类零件修补方法/Repair method of type A parts用毛笔蘸同颜色的自干漆将挂钩内侧少漆处来回涂抹，直至看不到基材或底涂为止，涂抹之处需平坦，无堆积和流挂Use a brush to paint the inside of hook repeatly with the same colored self-drying paint until the base material or primer is all covered. The painting area needs to be smooth. No overlap or run-down.5.3.2 B类零件修补方法/Repair method of type B parts操作要领/Operation gist:拆屏蔽屏蔽除尘喷涂烘干Shield Dust removal Painting Stoving Shield removal5.3.2.1 屏蔽/Shield将零件同一平面上不需要修补的区域用报纸和低温胶带屏蔽起来。

Shield the area of the same level of parts, which does not need repairing, with newspaper or low-temperature plaster.5.3.2.2 除尘/Dust removing用压缩空气将打磨处及周边区域的水痕、脏污、灰尘清理干净Clean the watermark, stain, dust surrounding the polishing spot with compressed air.5.3.2.3 喷涂/ Paint spraying采用纵横交错的喷涂手法，用指定油漆对修补打磨区域进行喷涂，保证总膜厚达到80~180μmWith cross spraypainting, spray the polishing area with the same colored and same series of paint to ensure the thickness of 90~195μm.5.3.2.4 烘干/Baking按照油漆的干燥条件用热风机将喷涂区域烘干，直至用指甲按无痕迹为止。
