①**白斑/粉化**：溶液过浓或中和不彻底，盐析出→稀释、充分水洗中和②**不均/斑驳**：表面有油或氧化皮→着色前酒精+洗剂彻底去油、酸洗③**流痕**：喷涂过厚或叠加未干→薄喷多层、层间待干④**色浅/不反应**：湿度不足、氨挥发尽或溶液失效→补湿补氨、换新液、检查密封⑤**色偏红无蓝黑**：硫化液已氧化失效→现配现用、避光保存⑥**银发黄**：硫化钠过强→改用肝硫或降浓度⑦**氯盐体系泛白**：未及时封护→水洗后 24 小时内封护。
①**White bloom/chalk**: too strong or poorly neutralized, salts precipitate → dilute, rinse and neutralize fully ②**Uneven/mottled**: oil or scale → degrease with alcohol+detergent, pickle first ③**Runs**: sprayed too heavy or layered wet → thin coats, let each dry ④**Pale/no reaction**: low humidity, spent ammonia, or dead solution → humidify, refill ammonia, mix fresh, check seal ⑤**Only red, no blue-black**: sulfide oxidized → mix fresh, store dark ⑥**Silver yellowing**: Na₂S too strong → use LoS or lower concentration ⑦**White bloom on chloride work**: not sealed in time → rinse and seal within 24 h. ---
