    鹽霧試驗

     

    [項目介紹]  

    鹽霧試驗是一種利用鹽霧試驗設備所創造的人工模擬鹽霧環境條件來確認產品或金屬材料耐腐蝕性能的環境試驗。試驗的嚴苛程度取決于曝露持續時間。

    實驗室模擬鹽霧可以分為三類:中性鹽霧試驗、醋酸鹽霧試驗、銅鹽加速醋酸鹽霧試驗。    

     (1)中性鹽霧試驗(NSS試驗)是出現最早目前應用領域最廣的一種加速腐蝕試驗方法。它采用5%的氯化鈉鹽水溶液,溶液PH值調在中性范圍(6.57.2)作為噴霧用的溶液。試驗溫度均取35℃,要求鹽霧的沉降率在12ml/80cm/h

     (2) 醋酸鹽霧試驗(ASS試驗)是在中性鹽霧試驗的基礎上發展起來的。它是在5%氯化鈉溶液中加入一些冰醋酸,使溶液的PH值降為3左右,溶液變成酸性,最后形成的鹽霧也由中性鹽霧變成酸性。它的腐蝕速度要比NSS試驗快3倍左右。

     (3) 銅鹽加速醋酸鹽霧試驗(CASS試驗)是國外新近發展起來的一種快速鹽霧腐蝕試驗,試驗溫度為50℃,鹽溶液中加入少量銅鹽-氯化銅,強烈誘發腐蝕。它的腐蝕速度大約是NSS試驗的8倍。
