(1)飲水機殼體的涂裝前處理工藝
熱水洗(30s,50~65 ℃ ) → 預脫脂(60s,50~65 ℃)→脫脂(150s,50~65 ℃) →水洗1(直排)→水洗1[30s,室溫(RT)]→水洗2(30s,RT)→新鮮水直噴→表調(30s,RT)→磷化(150s,50~60 ℃)→水洗3(30s,RT)→水洗4(30s,RT)→新鮮純水直噴。
(2)空調器殼體涂裝前處理工藝
熱水洗(40s,50~65 ℃) →預脫脂(80s,50~65℃ ) →脫脂(120s,50~65℃ ) →水洗1(45s,RT)→水洗2(50s,RT)→新鮮水直噴→表調(45s,RT)→磷化(150s,38~45 ℃) →水洗3(45s,RT)→水洗4(50 s,RT)→純水洗(50s,RT)→新鮮純水直噴。
(3)一種特殊的涂裝前處理工藝
脫脂磷化(90s,120~140 ℃ )→水洗1(60s,120~140 ℃ )→純水噴(5s,RT)→水洗2(60s,RT)→純水噴(5s,RT)。
