1、用碱洗液清洗

1. Clean with alkaline solution

在机箱机柜制作成型后并没有完全的完工，需要对它进行碱洗，肯定很多人会有疑问，为什么要对它进行碱洗？机箱机柜表面沾附很多油污，要售出高质量的机箱机柜，我们就必须对其进行清洁工作，我们其中一道工序就是对它进行清洗。我前面所提到的碱洗液是采用Na2C03  Na3P04  Na2Si03和添加剂组成。用碱洗液洗完还需用清水进行擦洗，目的是擦除碱洗液残留物。

The cabinet is not completely finished after it is made. It needs to be washed with alkali. Many people will have doubts about why it needs to be washed with alkali? There are a lot of oil stains on the surface of chassis and cabinet. To sell high-quality chassis and cabinet, we must clean them. One of our processes is to clean them. The alkali lotion I mentioned earlier is composed of na2c03, na3p04, na2si03 and additives. After washing with alkaline detergent, clean water is needed to wipe the residue of alkaline detergent.

2、使用去氧化膜

2. Use to remove oxide film

机箱外壳表面通过自然形成的氧化膜一般都不均匀且是非连续薄膜，在对机箱机柜表面涂装时必须提前一步对它进行彻 底的处理，对于压铸件来说可使用硝酸来对表面进行氧化膜处理。去除氧化膜后我们还需用清水进行进一步处理。

The naturally formed oxide film on the surface of the cabinet shell is generally non-uniform and discontinuous. When painting the surface of the cabinet, it must be thoroughly removed one step in advance. For die castings, nitric acid can be used to treat the oxide film on the surface. After removing the oxide film, we need water for further treatment.
                

3、进行化学转化

3. Chemical conversion

进行完前面的几步后，我们还要对它进行化学转化处理，我们需要其表面能够形成密而均匀的连续薄膜，这一步的工艺处理等同于对其进行磷化处理，但它们使用的溶液不同。机箱机的电子外壳转化膜以铬酸/盐酸、磷酸/盐酸和氟氢酸为基础，转化膜质量通常为215g/㎡，转化膜形成后，必须用清水清洗，然后用热风干燥，以增强膜层的硬度。

After the previous steps, we need to carry out chemical conversion treatment on it. We need to form a dense and uniform continuous film on its surface. The process treatment in this step is equivalent to phosphating treatment, but they use different solutions. The conversion film of the electronic case of the case machine is based on chromic acid / hydrochloric acid, phosphoric acid / hydrochloric acid and hydrofluoric acid. The quality of the conversion film is usually 215g / m2. After the conversion film is formed, it must be cleaned with clean water and then dried with hot air to enhance the hardness of the film.

总之，一个完好的机箱机柜产品必须要有美观性，外观也是给客户的印象，这一点很重要。试想，你是客户去购置机箱发现其表面脏兮兮的，肯定不会有好印象，所以，细节是成就事业必不可少的部分！

In a word, a good cabinet product must be beautiful, and the appearance also gives the impression of customers, which is very important. Just imagine, if you are a customer to buy a chassis and find its surface dirty, you will not have a good impression. Therefore, details are an essential part of achieving your career!
