Use two sets of tips and bells: one for operation, the other for checking, cleaning, and repairing. 提高喷枪和旋杯维护级别。使用两套设备，一套在作业时，另一套用来检查，清洗和修护。 Keep booths clean (clean every night if possible, weekly if not). 保持车间清洁（最好每晚清洗，不行的话，每周清洗）,Prevention of Dirt Problems - Plant Strategy 预防颗粒缺陷 车间策略,Keep environmental dirt out of the plant 防止作业区周边环境带来的颗粒 Control process to prevent generation of dirt 施工流程管控，防止颗粒产生 Collect and remove dirt that does appear 收集及去除已存在的颗粒 Protect bodies from dirt fallout 防止颗粒沉降在工件上 Clean units that do get dirty 清洁已污染的地方 Carry out frequent audits to evaluate dirt situation and determine progress in improving it. 经常审核评估颗粒情况，确定改进方法,Other Defects That Look Like Dirt 其他疑似颗粒的缺陷,Defects That Look Like Dirt 疑似颗粒,Spray Application and “Dirt” 喷涂作业中的“颗粒”,Paint droplets (drops, spits, overspray) 涂料液滴 （滴，溅，过喷） Solvent pops and air bubbles 溶剂气泡和空气气泡 Gassing from plastic parts 塑料件本身的气泡 Substrate defects 其他底材缺陷,A lot of dirt is not dirt at
