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.

清洗机常见的几种生锈的原因：

Several common causes of rust in cleaning machine:

1、不锈钢表面存积着含有其他金属元素的粉尘或异类金属颗粒的附着物，在潮湿的空气中，附着物与不锈钢间的冷凝水，将二者连成一个微电池，引发了电化学反应，保护膜受到破坏，称之谓电化学腐蚀。

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、不锈钢表面粘附有机物汁液(如瓜菜、面汤、痰等)，在有水氧情况下，构成有机酸，长时间则有机酸对金属表面的腐蚀。

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、不锈钢表面粘附含有酸、碱、盐类物质(如装修墙壁的碱水、石灰水喷溅)，引起局部腐蚀。

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、在有污染的空气中(如含有大量硫化物、氧化碳、氧化氮的大气)，遇冷凝水，形成硫酸、硝酸、醋酸液点，引起化学腐蚀。

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.

超声波清洗机的清洗槽生锈怎么解决：

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

1、必须经常对装饰不锈钢表面进行清洁擦洗，去除附着物，消除引发修饰的外界因素。

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

2、使用强酸碱清洗液体的要使用316材质不锈钢，316材质能抵抗海水腐蚀。

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

3、市场上有些超声波清洗设备使用的不锈钢管化学成分不能符合相应国家标准，达不到304材质要求，也会引起生锈。

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.
