機箱外殼的日常維護對減少和避免電機在運行中發生故障是相當重要的，其中比較重要的方面便是保養清潔。那么機箱外殼怎么進行清潔才合適呢？

　　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?

　　用堿洗液清洗

　　在機箱外殼制作成型后并沒有真正的完工，需要對它進行堿洗，肯定很多人會有疑問，為什么要對它進行堿洗？機箱外殼表面沾附很多油污，要售出的機箱外殼，我們就須對其進行清潔工作，我們一道工序就是對它進行清洗。我前面所提到的堿洗液是采用Na2C03Na3P04Na2Si03和添加劑組成。用堿洗液洗完還需用清水進行擦洗，目的是擦除堿洗液殘留物。

　　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

　　機箱外殼表面通過自然形成的氧化膜一般都不均勻且是非連續薄膜，在對機箱外殼表面涂裝時須提前一步對它進行徹底的處理，對于壓鑄件來說可使用硝酸來對表面進行氧化膜處理。去除氧化膜后我們還需用清水進行進一步處理。

　　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.

　　進行化學轉化

　　進行完前面的幾步后，我們還要對它進行化學轉化處理，我們需要其表面能夠形成密而均勻的連續薄膜，這一步的工藝處理等同于對其進行磷化處理，但它們使用的溶液不同。機箱機的電子外殼轉化膜以鉻酸/鹽酸、磷酸/鹽酸和氟氫酸為基礎，轉化膜質量通常為215g/㎡，轉化膜形成后，須用清水清洗，然后用熱風干燥，以增強膜層的硬度。

　　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.

　　總之，一個的機箱外殼產品須要有美觀性，外觀也是給客戶的印象，這一點很重要。試想，你是客戶去購置機箱發現其表面臟兮兮的，肯定不會有好印象，所以，細節是成就事業必不可少的部分！更多內容就來網站www.metferro.com咨詢吧！

　　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!
