Causes 成因
- Poor cleaning of substrate prior to painting 喷涂前底材清洁不充分
- Lint containing overalls or clothes
工作服或衣物含有绒毛
- Spray booth dust problem due to dirty filters causing incorrect air supply, extraction and pressure
喷漆房因过滤器脏污导致空气供应、抽排和压力不正确而产生灰尘问题
- Intake of contaminated air from outside the spray booth (polishing residues, fine dust etc.)
喷漆房外吸入受污染的空气（抛光残留物、细微灰尘等）
Prevention 措施

在喷涂新漆之前进行彻底清洁
- Use lint-free overalls and cloth
使用无绒工作服和布料
- Ensure regular maintenance and filter changes of the booth

- Ensure polishing/finishing areas are away from the paintshop and separated by filtered and ventilated systems
确保抛光/修补区域远离喷漆车间，并通过过滤和通风系统进行隔离
How to repair 如何修补
- Polishing with a propriety high gloss polish. More extensive defects are to be sanded down for re-painting 使用专用高光抛光剂进行抛光。对于更严重的缺陷，需要打磨后重新喷涂。
