不銹鋼網真的不生銹嗎?生銹的不銹鋼網是假的嗎?為什么不銹鋼絲網會生銹?下面，小編將一一揭曉。不銹鋼是鋼鐵工業的一項重大發明，不銹鋼產品也已經普及到每個家庭，其耐腐蝕性已經贏得了廣大消費者的青睞，尤其是80、90后的人們，更是深受喜愛。然而，更近一些人反映，一些不銹鋼制品不銹鋼絲網生銹，質疑這是假冒偽劣產品。

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.

雖然有一小部分產品是劣質的，但是大部分是合格的，只是人們對不銹鋼缺乏了解。不銹鋼是一種以鐵為主要材料的合金。鉻元素在不銹鋼表面形成一層極薄、強度高、密度大、穩定的富鉻氧化膜(保護膜)。這種薄膜成功地阻止了氧分子的滲透，從而使不銹鋼具有了抗腐蝕的能力。

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，如果薄膜不斷損壞，空氣或液體中的氧氣會不斷滲透，或者金屬中的鐵原子會不斷暴露，形成松散的氧化鐵，金屬表面會不斷被侵蝕。膜損傷不銹鋼金屬網的表面形式有很多,日常生活中常見的有幾種:不銹鋼金屬網沉積表面上含有其他金屬元素的附件,的金屬顆粒灰塵或潮濕的空氣,附件和不銹鋼網,兩個之間的冷凝水在一起作為一個微型電池,引發了電化學反應。

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.

保護膜的破壞稱為電化學腐蝕。不銹鋼網表面附著有機汁液(如蔬菜、面湯、痰液等)，在水中和氧氣、有機酸、有機酸的存在下，對金屬表面進行長時間的腐蝕。不銹鋼網表面附著含有酸、堿、鹽等物質(如裝飾墻的堿水、石灰水等)，造成局部腐蝕。

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.

在被污染的空氣中(如含有大量的硫化物、碳、氮氧化物的大氣中)，遇凝結水時，會形成硫酸、硝酸、醋酸等液態點，造成化學腐蝕。以上這些情況都有可能造成不銹鋼絲網生銹，所以不銹鋼絲網不完全不生銹，為了保持其表面的性光亮，必須對其表面進行清洗、鈍化等處理。

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.
