預防塵點三步驟

1、底材噴涂前必須使用無塵布清潔。

2、噴漆環境要求密封,而且還必須有抽風系統和流掛系統。

3、清理噴槍,更換油漆.(油漆比例,噴槍霧化等等都需要注意)

如果出現塵點不良品,可參考以下解決方案

(1)、涂裝工藝流程:(不良品→不良打磨)工件表面的清潔→噴涂UV翻新水(膜厚為3-5um)→65°烤箱烘烤5min→翻噴UV光油→IR流平(60±10℃×4~6min)→UV固化(700±100mj/cm2)→檢驗,成品。

(2)、施工粘度:8±1秒(巖田2#杯)    

(3)、施工氣壓:3-4Kg/cm2

UV翻新水并不是把原有UV漆膜除去,而是起承上啟下作用使原UV漆膜鉸鏈上再噴涂的UV,達到附著,使不良品變為良品。主要用于底UV與翻噴UV之間的附著力。
