塑料電鍍常見故障分析

塑料表面有皺紋、有接縫、鼓泡 注塑模具不光潔;注塑條件不當;塑料含水份
粗化后表面親水性差 塑料表面被脫膜劑和礦物油污染;粗化不足,如溫度低,時間短;粗化時沒有翻動工件;塑料牌號不對、回料太多
粗化后塑料表面有黃色疏松層 粗化過度,例如溫度高時間長;粗化中硫酸濃度過高,退鍍時過腐蝕或多次退鍍
化學鍍時局部有鍍層或沉積很慢 粗化液清洗不徹底;解膠溶液太稀或溫度低;化學鍍中主鹽和還原劑含量低或穩定劑含量高
某固定部位無鍍層 該部位有應力;粗化不足或無翻動;該部位清洗時不宜清詵徹底
鑲層起泡或結臺力差,露塑 粗化不足或粗化后清洗不佳;塑料本身有應力或回料太多,牌號不對;工件表面臟污未除凈;零件翻動不夠,凸部清洗過度;有氣體附在工件表面
表面粗糙或有細麻砂 模具光潔度不夠;粗化過度;化學鍍液中懸浮物過多;
產品變形 操作溫度過高;塑料太薄;掛具觸點彈性太大;烘溫過高
化學鍍后表面有粉狀物 化學鍍反應過快;絡合劑、穩定劑不足
