户外机箱机柜出现腐蚀的原因有哪些？

发布时间：2021-02-11 来源：http://www.tongyuhengcheng.com/ 浏览量：

无论机箱机柜在制造时采用的是什么材质，由于天气潮湿，在长时间的使用后都会造成机箱机柜出现锈蚀现象。那么，户外机箱机柜出现腐蚀现象的原因有哪些呢？这就需要我们在日常生活中注意以下所说的一些问题了，下面我们就一起来了解一下。

No matter what material is used in the manufacture of the cabinet, due to the humid weather, the cabinet will rust after a long time of use. So, what are the reasons for the corrosion of outdoor cabinets? This requires us to pay attention to some of the problems mentioned below in our daily life. Let's understand them together.

1.表面污染：附着在户外机箱机柜工件表面的油污、灰尘以及酸、碱、盐等，会在一定的条件下转化为腐蚀介质。然后与不锈钢件中的某些成分发生化学反应，从而产生化学腐蚀而出现生锈的现象。

1. Surface pollution: the oil, dust, acid, alkali, salt, etc. on the surface of outdoor cabinet will be transformed into corrosive medium under certain conditions. Then, it reacts with some components of stainless steel parts to produce chemical corrosion and rust.

2.表面划伤：各种划伤对户外机箱机柜钝化膜的破坏，使不锈钢保护能力降低。因此易与化学介质发生反应，产生化学腐蚀而生锈。

2. Surface scratch: the damage of various scratches to the passive film of outdoor cabinet reduces the protection ability of stainless steel. Therefore, it is easy to react with chemical medium, resulting in chemical corrosion and rust.

3.清洗问题：户外机箱机柜在酸洗钝化后，由于清洗不干净而造成的残液存留，直接会腐蚀影响到不锈钢件。

3. Cleaning problem: after pickling and passivation, the residual liquid caused by unclean cleaning will directly affect the stainless steel parts.
