    不锈钢卷闸门为何还会生锈呢?

    很多人可能都会有这样一个疑问,为什么不锈钢卷闸门还会生锈呢?针对这个问题,济南卷帘门厂家为大家做一下解答!
    Many people may have such a question, why does stainless steel coil gate still rust? In view of this problem, Jinan Rolling Curtain Door Factory will give you some answers!
    不锈钢卷闸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。
    The stainless steel rolling gate is mainly formed by a thin, fine, stable and strong chromium-rich oxide film on its surface, that is, protective film. It can prevent the oxygen atoms from infiltrating and oxidizing, thus gaining the function of anti-rust. Once the film is continuously destroyed, oxygen atoms in air or liquid will continuously infiltrate or iron atoms in metal will continuously segregate, forming loose iron oxide, and metal surface will be continuously 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:
    This kind of surface protective film is destroyed in many ways. There are several common ways in daily life:
    1、不锈钢卷闸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. The surface of stainless steel coiled gate is deposited with dust containing other metal elements or adhesives of different metal particles. In humid air, the adhesives and condensate water between stainless steel and stainless steel connect them into a micro-battery, which leads to electrochemical reaction, and the protective film is destroyed. It is called electrochemical corrosion.

    2、不锈钢卷闸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 gate is adhered with organic juice, such as melon and vegetable, noodle soup, phlegm and so on. Under the condition of water and oxygen, organic acid is formed, while organic acid will corrode the metal surface for a long time.
    3、清洗不锈钢卷闸门,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 coiled gates and brushing them with hard materials such as iron wire will seriously damage the protective film, so that the metal surface is easily oxidized and corroded.
