First of all, we need to understand that stainless steel forms a very thin, solid, fine and stable protective film on the surface to prevent the infiltration and oxidation of oxygen atoms and achieve the role of anti-corrosion. When the protective film is damaged by external reasons, air, liquid and oxygen atoms will continue to penetrate and iron atoms in the metal will continue to separate, To produce iron oxide, then rust is only a matter of time.

清洗機常見的幾種生銹的原因：

Several common causes of rust in cleaning machine:

1、不銹鋼表面存積著含有其他金屬元素的粉塵或異類金屬顆粒的附著物，在潮濕的空氣中，附著物與不銹鋼間的冷凝水，將二者連成一個微電池，引發了電化學反應，保護膜受到破壞，稱之謂電化學腐蝕。

1. There are dust containing other metal elements or attachments of dissimilar metal particles on the surface of stainless steel. In humid air, the condensate between the attachments and stainless steel connects them into a micro battery, which leads to electrochemical reaction and damage to the protective film, which is called electrochemical corrosion.

2、不銹鋼表面粘附有機物汁液(如瓜菜、面湯、痰等)，在有水氧情況下，構成有機酸，長時間則有機酸對金屬表面的腐蝕。

2. The surface of stainless steel adheres to organic juice (such as melons and vegetables, noodle soup, phlegm, etc.), which constitutes organic acid in the case of water and oxygen. For a long time, the corrosion of organic acid on the metal surface will be reduced.

3、不銹鋼表面粘附含有酸、堿、鹽類物質(如裝修墻壁的堿水、石灰水噴濺)，引起局部腐蝕。

3. The adhesion of stainless steel surface contains acid, alkali and salt substances (such as alkali water and lime water splashing on the decoration wall), causing local corrosion.

4、在有污染的空氣中(如含有大量硫化物、氧化碳、氧化氮的大氣)，遇冷凝水，形成硫酸、硝酸、醋酸液點，引起化學腐蝕。

4. In polluted air (such as atmosphere containing a large amount of sulfide, carbon oxide and nitrogen oxide), sulfuric acid, nitric acid and acetic acid liquid points will be formed in the presence of condensate, causing chemical corrosion.

超聲波清洗機的清洗槽生銹怎么解決：

How to solve the rust in the cleaning tank of ultrasonic cleaning machine:

1、必須經常對裝飾不銹鋼表面進行清潔擦洗，去除附著物，消除引發修飾的外界因素。

1. The decorative stainless steel surface must be cleaned and scrubbed frequently to remove attachments and eliminate external factors causing modification.

2、使用強酸堿清洗液體的要使用316材質不銹鋼，316材質能抵抗海水腐蝕。

2. 316 stainless steel shall be used for strong acid-base cleaning liquid, which can resist seawater corrosion.

3、市場上有些超聲波清洗設備使用的不銹鋼管化學成分不能符合相應國家標準，達不到304材質要求，也會引起生銹。

3. The chemical composition of stainless steel pipes used in some ultrasonic cleaning equipment on the market can not meet the corresponding national standards, which can not meet the 304 material requirements, and will also cause rust.
