机箱外壳的日常维护对减少和避免电机在运行中发生故障是相当重要的，其中比较重要的方面便是保养清洁。那么机箱外壳怎么进行清洁才合适呢？

　　The daily maintenance of the case shell is very important to reduce and avoid the failure of the motor in operation, and the most important aspect is maintenance and cleaning. So how to clean the case shell is appropriate?

　　用碱洗液清洗

　　在机箱外壳制作成型后并没有真正的完工，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？机箱外壳表面沾附很多油污，要售出的机箱外壳，我们就须对其进行清洁工作，我们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Na2C03Na3P04Na2Si03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。

　　Clean with alkali lotion

　　After the case shell is made and molded, it is not really completed, and it needs to be alkali washed. Surely many people will have questions, why should it be alkali washed? The surface of the case shell is stained with a lot of oil. To sell the perfect case shell, we have to clean it. One of our processes is to clean it. The alkaline lotion I mentioned earlier is composed of Na2C03Na3P04Na2Si03 and additives. After washing with alkali lotion, you also need to scrub with water to erase the residue of alkali lotion.

　　使用去氧化膜

　　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，在对机箱外壳表面涂装时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。

　　Use a deoxidizing film

　　The surface of the case shell through the naturally formed oxide film is generally uneven and discontinuous film, in the case shell surface coating must be one step in advance of it is thoroughly removed, for die casting can use nitric acid to the surface of the oxide film treatment. After removing the oxide film, we also need water for further treatment.

　　进行化学转化

　　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，须用清水清洗，然后用热风干燥，以增强膜层的硬度。

　　Chemical conversion

　　After the first steps, we need to chemically transform it, we need to form a dense, uniform, continuous film on the surface, and this step is the same as phosphating it, but they use different solutions. The electronic shell conversion film of the chassis machine is based on chromic acid/hydrochloric acid, phosphoric acid/hydrochloric acid and fluorine hydrochloric acid. The quality of the conversion film is usually 215g/㎡. After the formation of the conversion film, it must be cleaned with water, and then dry with hot air to enhance the hardness of the film layer.

　　总之，一个的机箱外壳产品须要有美观性，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！更多内容就来网站www.metferro.com咨询吧！

　　In short, a perfect case shell products need to have beauty, appearance is also the first impression to customers, this is very important. Imagine, you are a customer to buy the chassis found its surface dirty, certainly will not have a good impression, so, the details are an essential part of the achievement of career!
