不锈钢网真的不生锈吗?生锈的不锈钢网是假的吗?为什么不锈钢丝网会生锈?下面，小编将一一揭晓。不锈钢是钢铁工业的一项重大发明，不锈钢产品也已经普及到每个家庭，其耐腐蚀性已经赢得了广大消费者的青睐，尤其是80、90后的人们，更是深受喜爱。然而，更近一些人反映，一些不锈钢制品不锈钢丝网生锈，质疑这是假冒伪劣产品。

Is the stainless steel mesh really rustless? Is the rusty stainless steel mesh fake? Why is the stainless steel mesh rusty? Below, we will find out one by one. Stainless steel is a major invention of the iron and steel industry, and stainless steel products have been widely used in every family. Its corrosion resistance has won the favor of the majority of consumers, especially the 80's and 90's. However, some people recently reported that some stainless steel products stainless steel wire mesh rusty, questioned that this is fake and inferior products.

虽然有一小部分产品是劣质的，但是大部分是合格的，只是人们对不锈钢缺乏了解。不锈钢是一种以铁为主要材料的合金。铬元素在不锈钢表面形成一层极薄、强度高、密度大、稳定的富铬氧化膜(保护膜)。这种薄膜成功地阻止了氧分子的渗透，从而使不锈钢具有了抗腐蚀的能力。

Although a small part of the products are inferior, most of them are qualified, but people lack of understanding of stainless steel. Stainless steel is an alloy with iron as its main material. Chromium element forms a very thin, high strength, high density and stable chromium rich oxide film (protective film) on the surface of stainless steel. This kind of film successfully prevents the permeation of oxygen molecules, so that stainless steel has the ability of anti-corrosion.

但是，如果薄膜不断损坏，空气或液体中的氧气会不断渗透，或者金属中的铁原子会不断暴露，形成松散的氧化铁，金属表面会不断被侵蚀。膜损伤不锈钢金属网的表面形式有很多,日常生活中常见的有几种:不锈钢金属网沉积表面上含有其他金属元素的附件,的金属颗粒灰尘或潮湿的空气,附件和不锈钢网,两个之间的冷凝水在一起作为一个微型电池,引发了电化学反应。

However, if the film is constantly damaged, the oxygen in the air or liquid will continue to penetrate, or the iron atoms in the metal will continue to be exposed, forming loose iron oxide, and the metal surface will continue to be eroded. There are many kinds of surface forms of stainless steel wire mesh damaged by film, and there are several common types in daily life: accessories containing other metal elements on the deposited surface of stainless steel wire mesh, metal particles dust or humid air, accessories and stainless steel wire mesh, and the condensate between the two as a micro battery, triggered the electrochemical reaction.

保护膜的破坏称为电化学腐蚀。不锈钢网表面附着有机汁液(如蔬菜、面汤、痰液等)，在水中和氧气、有机酸、有机酸的存在下，对金属表面进行长时间的腐蚀。不锈钢网表面附着含有酸、碱、盐等物质(如装饰墙的碱水、石灰水等)，造成局部腐蚀。

The destruction of the protective film is called electrochemical corrosion. The surface of stainless steel mesh is attached with organic juice (such as vegetable, noodle soup, sputum, etc.), which corrodes the metal surface for a long time in the presence of water, oxygen, organic acid and organic acid. The surface of stainless steel mesh contains acid, alkali, salt and other substances (such as alkali water, lime water, etc.) which cause local corrosion.

在被污染的空气中(如含有大量的硫化物、碳、氮氧化物的大气中)，遇凝结水时，会形成硫酸、硝酸、醋酸等液态点，造成化学腐蚀。以上这些情况都有可能造成不锈钢丝网生锈，所以不锈钢丝网不完全不生锈，为了保持其表面的性光亮，必须对其表面进行清洗、钝化等处理。

In the polluted air (such as the atmosphere containing a large amount of sulfide, carbon and nitrogen oxides), when meeting with condensed water, liquid points such as sulfuric acid, nitric acid and acetic acid will be formed, causing chemical corrosion. All of the above conditions may cause stainless steel wire mesh rust, so stainless steel wire mesh is not completely rusty. In order to keep its surface permanently bright, it is necessary to clean and passivate its surface.
