鹽(yan)(yan)霧(wu)試(shi)(shi)(shi)驗(yan)(yan)機可以做(zuo)的試(shi)(shi)(shi)驗(yan)(yan)有四(si)種:中性鹽(yan)(yan)霧(wu)試(shi)(shi)(shi)驗(yan)(yan)(NSS)、銅加速乙l酸(suan)鹽(yan)(yan)霧(wu)試(shi)(shi)(shi)驗(yan)(yan)(CASS)、交變鹽(yan)(yan)霧(wu)試(shi)(shi)(shi)驗(yan)(yan)、醋酸(suan)鹽(yan)(yan)霧(wu)試(shi)(shi)(shi)驗(yan)(yan)(ASS試(shi)(shi)(shi)驗(yan)(yan))。當

然，不(bu)同的試驗不(bu)光是試獫所需溶液不(bu)一樣，就連(lian)箱體的設(she)計(ji)與結(jie)構(gou)可能也有所不(bu)同。

一(yi)、中性(xing)鹽霧試驗(yan)(yan)機(ji)(ji)的溫度(du)(du)要(yao)求在(35+2)C ，濕度(du)(du)大(da)于95%，超快速冷熱沖擊(ji)試驗(yan)(yan)機(ji)(ji)，降霧量為(wei)1 ~ 2mL/80cm*h噴(pen)嘴壓力(li)為(wei)

78.5~ 137.3kPa(0.8~1.4kgf/cm2)。是(shi)在鹽(yan)霧試驗箱(xiang)內(nei)，將(jiang)含(han)有(5:上0.5)%氯化鈉、pH值為6.5~7.2的鹽(yan)水通過噴(pen)霧裝置進行噴(pen)

霧(wu)，讓鹽霧(wu)沉(chen)降到(dao)待測試(shi)驗件上，超快速冷(leng)熱沖擊試(shi)驗機(ji)定制， 經過一定時間觀察其(qi)表面腐蝕(shi)狀態(tai)。

二、 銅加(jia)速(su)乙(yi)l酸鹽霧(wu)試驗(CASS)就是在一般鹽霧(wu)試驗的(de)基礎上(shang)5%氯化(hua)鈉鹽水中加(jia)入2水氯化(hua)銅，使(shi)其濃度為0.26g/L ，再用乙(yi)l酸調

節PH，使鹽(yan)霧收集液的PH值為(wei)3.1-3.3.

三、交變鹽(yan)霧試(shi)驗(yan)是-種綜合鹽(yan)霧試(shi)驗(yan)(采用交變鹽(yan)霧試(shi)驗(yan)箱(xiang)實現。

四、醋(cu)酸(suan)鹽(yan)霧(wu)(wu)試驗(ASS試驗)是在(zai)中性(xing)鹽(yan)霧(wu)(wu)試驗的(de)基礎上發(fa)展(zhan)起來的(de)。它是在(zai)5%氯化鈉溶(rong)液中加(jia)入一些(xie)冰醋(cu)酸(suan)。
