不锈钢卷帘门为何还会生锈呢?

来源:http://www.jnhsjlm.com 日期:2020-07-15 发布人:guanli
  为什么不锈钢卷帘门还会生锈呢?不锈钢卷帘门主要是靠其表面形成的一层薄而细密、稳定、坚固的富铬氧化膜,也就是防护膜。它可以防止氧原子的渗入、氧化,从而获得抗锈的功能。一旦这种薄膜遭到了不断地破坏,空气或着液体中氧原子就会不断渗入或金属中铁原子不断地析离出来,形成疏松的氧化铁,金属的表面也就受到不断地锈蚀。
  Why does stainless steel rolling shutter door still rust? Stainless steel rolling shutter door mainly relies on its surface to form a thin and fine, stable, strong chromium rich oxide film, that is, protective film. It can prevent the penetration and oxidation of oxygen atoms, so as to obtain the anti rust function. Once the film is constantly damaged, oxygen atoms in air or liquid will continue to penetrate or metal iron atoms will continue to separate out, forming loose iron oxide, and the metal surface will be constantly corroded.
  这种表面防护膜受到破坏的形式很多,日常生活中常见的有以下几种:
  There are many forms of damage to the surface protective film, which are common in daily life as follows:
  1、不锈钢卷帘门表面存积着含有其他金属元素的粉尘或异类金属颗粒的附着物,在潮湿的空气中,附着物与不锈钢间的冷凝水,将二者连成一个 微电池,引发了电化学反应,保护膜受到破坏,称之谓电化学腐蚀。
  1. There are dust containing other metal elements or attachments of different metal particles on the surface of stainless steel rolling shutter door. In humid air, the condensation water between the attachment and stainless steel connects them into a micro cell, which causes electrochemical reaction and damages the protective film, which is called electrochemical corrosion.

  2、不锈钢卷帘门表面粘附有机物汁液,例如瓜菜、面汤、痰等,在有水氧的情况下,构成有机酸,长时间则有机酸会腐蚀金属表面。
  2. The surface of stainless steel rolling shutter door adheres organic juice, such as melon and vegetable, noodle soup, phlegm, etc. in the case of water and oxygen, organic acid forms organic acid, which will corrode the metal surface for a long time.
  3、清洗不锈钢卷帘门,用铁丝之类比较硬的东西进行刷洗,会严重破坏防护膜,以致于金属表面容易氧化侵蚀。
  3. Cleaning stainless steel rolling shutter door with iron wire and other hard things will seriously damage the protective film, so that the metal surface is easy to be oxidized and eroded.
  所以所,不是不锈钢的卷帘门就不会生锈的!所以大家平日有空可以用毛巾抹布擦洗卷帘门,这样卷帘门就不会那么容易老化。
  Therefore, if it is not stainless steel, the rolling shutter door will not rust! So we can use towel cloth to clean the rolling shutter door when we have time, so that the rolling shutter door will not be so easy to aging.
