众所周知，不锈钢岗亭是岗亭中的一种，因为这种岗亭使用的制作材料是不锈钢钢材，所以称之为不锈钢岗亭;又因其的硬度非常强，所以在制作过程中需要对不锈钢进行多种加工。如拉深工艺、胀形工艺等。在制成成型之后，往往会对其喷漆，那么喷漆的目的是什么呢?

　　第一：因为不锈钢岗亭本身的颜色是比较单调的，很难满足用户追求美感的需求，所以采用油漆喷涂工艺来给岗亭上色，从而就会有各种各样的不同颜色的岗亭了，也可以根据客户喜欢的颜色来喷涂。

　　第二：给不锈钢岗亭上色，不但是让其拥有更多的颜色，更加美观，同时也是对岗亭进行一次镀膜，在钢结构的表面形成一层保护膜，通过调整保护膜的厚度，使不锈钢岗亭产生各种颜色，并且可以改变不锈钢岗亭的纹路、图案等等。

　　第三：如果喷漆工艺做得好，能够减少不锈钢岗亭的腐烂性，不锈钢岗亭的耐腐蚀性取决于铬，但是因为铬是钢的组成部分之一，所有金属都和大气中的氧气进行反应，在表面形成氧化膜。但在普通碳钢上形成的氧化铁会继续进行氧化，使锈蚀不断扩大，最终形成孔洞。因此可以利用油漆来进行电镀来保证碳钢表面。

As we all know, the stainless steel sentry box is one of the sentry boxes, because this kind of sentry box is made of stainless steel, so it is called the stainless steel sentry box. Because of its very strong hardness, stainless steel needs to be processed in various ways in the manufacturing process. Such as drawing process, bulging process, etc. After it is made into shape, it is often painted, so what is the purpose of painting?

First: because the color of the stainless steel sentry box itself is relatively monotonous, it is difficult to meet the needs of users in pursuit of aesthetic feeling, so paint spraying process is adopted to color the sentry box, thus there will be a variety of sentry boxes with different colors, which can also be sprayed according to the colors that customers like.

Second: Color the stainless steel sentry box, not only to make it have more colors and more beautiful, but also to coat the sentry box once to form a protective film on the surface of the steel structure. By adjusting the thickness of the protective film, the stainless steel sentry box can produce various colors and can change the lines, patterns and so on of the stainless steel sentry box.

Third: If the painting process is done well, the rottenness of the stainless steel box can be reduced. The corrosion resistance of the stainless steel box depends on chromium. However, because chromium is one of the components of steel, all metals react with oxygen in the atmosphere to form an oxide film on the surface. However, iron oxide formed on ordinary carbon steel will continue to be oxidized, causing corrosion to continue to expand and eventually form holes. Therefore, paint can be used for electroplating to ensure the surface of carbon steel.
