關于旋轉蒸發器的堿清洗方法是什么?

http://www.sewingmachine-review.com/Admin發布于 關鍵詞:

今天一個老顧客購買R201D旋轉蒸發器,其實驗室一直用的都是這一款旋蒸,當他發來老圖片的時候,我發現,旋轉屏和蒸發瓶已經污垢很重了,所以今天來介紹一下旋轉蒸發器的堿清洗。

1.旋轉蒸發器的堿清洗又簡稱為堿洗,堿清洗是以強堿性或堿性的化學藥劑作為清洗劑去疏松、乳化和分散金屬設備內沉積物的一類方法。

2.常用的堿清洗藥劑:氫氧化鈉、碳酸鈉、磷酸氫二鈉和硅酸鈉。

3.堿清洗時要同時添加表面活性劑去潤濕油脂、塵埃和生物物質,以提高清洗效果。 

4.堿清洗常用于以下幾方面:除去系統或設備中的油脂和安裝時遺留的碎屑;與酸洗交替使用,以除去諸如硅酸鹽等酸清洗難子除去的沉積物;堿清洗也用于酸清洗之后,以中和水中或設備中殘留的酸,降低其腐蝕性。如果冷卻水系統中有鋁或鍍鋅鋼件,則堿清洗時應特別慎重,因為這些兩性金屬既能溶于酸,也能溶于堿中。

以上就是旋轉蒸發器關于堿清洗的一些常識和注意事項,請大家作為參考,有更多的意見和建議歡迎多多咨詢和交流VX:gykryq668.
