Paint spraying process for rigid surfaces刚性表面的油漆喷涂工艺

Note:提示：

♦  All paint repairs to rigid surfaces must comply with manufacturer's standards. Confirm the repair area and select the repair scope, such as partial repair, complete repair, or complete vehicle repair; if it is a collision damage, perform corresponding repair after sheet metal repair according to the damage situation, or spray paint after replacing parts.刚性表面的所有油漆修理必须符合厂商标准。确认修补区域并选择修补范围，例如局部修补、整块修补、整车修补；如果是碰撞损坏，根据损坏情况进行钣金修复后相应的修补，或者更换零件后进行喷漆。

1.

The fenders have serious scratches and require partial spraying (paint touch-up).翼子板划痕较严重，采用局部喷涂(补漆)工艺

2.

Use P500# wet (water) sandpaper to sand the damaged paint surface (circular sanding)用P500＃湿(水)砂纸在受损漆面上进行打磨处理(圆打磨)

3.

After sanding, use degreasing agent to degrease and clean打磨完成后用脱脂剂进行除油，清洁

4.

When spraying the primer, try to control the range of the primer. The coating at the edges should be gradual and not stepped.喷涂中涂底漆，尽量控制喷涂底漆的范围，边缘位置涂层要渐进，不要呈阶梯状

5.

Flash dry for 4-5 minutes, then dry for 20-30 minutes闪干4-5min，之后进行干燥，烘干20-30min Paint room temperature 70-80℃ (158-176ºF)烤漆房温度70-80℃(158-176ºF)

6.

After drying, wet sand with P800-1000# sandpaper烘干后，用P800-1000＃砂纸进行湿打磨

7.

Use 2000# fine water sandpaper to polish and expand the polishing range用2000＃细水砂纸进行打磨，并扩大打磨范围

8.

After sanding, use sticky gauze to remove dust before painting.打磨完成后用粘性纱布进行喷漆前的除尘工作

9.

Spray base paint喷涂底色漆 Air pressure 150-200kPa (21.8-29.0psi)空气压力150-200kPa(21.8-29.0psi) Spraying distance 20-30cm (7.87-11.81in)喷涂距离20-30cm(7.87-11.81in)   Caution:注意： ♦  The spray range is slightly wider than the previous layer to make a transition.喷涂范围一层比一层稍宽以做过渡。

10.

After flashing for 2-3 minutes, spray the second coat of primer until the joint position is no longer obvious.闪干2-3min后，喷涂第二道底色漆，直至接口位置已不明显 Air pressure 150-200kPa (21.8-29.0psi)空气压力150-200kPa(21.8-29.0psi) Spraying distance 20-30cm (7.87-11.81in)喷涂距离20-30cm(7.87-11.81in)

11.

Flash dry for 4-5 minutes, then dry for 20-30 minutes闪干4-5min，之后进行干燥20-30min Paint room temperature 70-80℃ (158-176ºF)烤漆房温度70-80℃(158-176ºF)

12.

After drying, use sticky gauze to remove dust before spraying varnish.干燥后用粘性纱布进行喷清漆前的除尘工作

13.

Spray clear paint to completely cover the base paint range喷涂透明漆，喷涂范围完全覆盖底色漆范围 Air pressure 150-200kPa (21.8-29.0psi)空气压力150-200kPa(21.8-29.0psi) Spraying distance 20-30cm (7.87-11.81in)喷涂距离20-30cm(7.87-11.81in)

14.

Flash dry for 2-3 minutes, then spray the second coat of clear paint to completely cover the range of the first coat of clear paint.闪干2-3min，喷涂第二道透明漆，喷涂范围完全覆盖第一层清漆的范围 Air pressure 150-200kPa (21.8-29.0psi)空气压力150-200kPa(21.8-29.0psi) Spraying distance 20-30cm (7.87-11.81in)喷涂距离20-30cm(7.87-11.81in)

15.

After spraying the clear paint, immediately replace it with water or add interface additives or thinners to the original clear paint.完成透明漆喷涂后，立刻换上驳口水或在原有透明漆中加入接口添加剂或稀释剂

16.

Spray 2-3 times of water or diluted transparent paint on the interface.在接口位置喷涂2-3次的驳口水，或经稀释的透明漆

17.

Dry in the paint room for 20-30 minutes在烤漆房烘干20-30min Paint room temperature 70-80℃ (158-176ºF)烤漆房温度70-80℃(158-176ºF)
