鹽霧腐蝕試驗箱必須滿足以下幾點?

發布日期:2022-04-26 點擊率:46

鹽霧腐蝕試驗箱由噴霧嘴、鹽水桶、試驗片支架、噴霧液收集容器、試驗室、鹽水補給桶、飽和桶、壓縮空氣之供給設備與排氣裝置等組成,設備的制造必須滿足以下幾點方可使用。

1、試驗箱所有管路應采用鈍性材料,不能對試驗有影響或本身被腐蝕。


2、噴霧嘴不可直接將試驗液噴向試樣,試驗箱頂部聚集的溶液不得滴落在試驗樣品上。


3、噴霧后的鹽水不能反復使用。


4、壓縮空氣不能含有油脂及灰塵,鹽霧腐蝕試驗箱須帶油污過濾器。


5、壓縮空氣噴霧前要預熱,以獲取均一溫度的噴霧。

6、收集溶液采用漏斗,漏斗要求80cm2。


7、試驗樣品的擺放需滿足15度至30度傾斜,樣品之間不可相互重疊。
