很多人認為不銹鋼卷簾門不會出現生銹的現象，實際上這是對不銹鋼缺乏了解的一種片面的錯誤看法。不銹鋼卷簾門在一定的條件下也會生銹的。濟南卷簾門廠小編來為您講解下吧。

Many people think that stainless steel roller shutter doors will not rust. In fact, this is a one-sided wrong view of the lack of understanding of stainless steel. Stainless steel roller shutter doors will rust under certain conditions. Let me explain it to you.

不銹鋼卷簾門具有抵抗大氣氧化的能力---即不銹性，同時也具有在含酸、堿、鹽的介質中乃腐蝕的能力---即耐蝕性。但其抗腐蝕能力的大小是隨其鋼質本身化學組成、加互狀態、使用條件及環境介質類型而改變的。

The stainless steel rolling shutter door has the ability to resist atmospheric oxidation, that is, rust resistance, and the ability to be corroded in the medium containing acid, alkali and salt, that is, corrosion resistance. However, the corrosion resistance of the steel varies with the chemical composition of the steel itself, the interaction state, the service conditions and the type of environmental media.

如304鋼管，在干燥清潔的大氣中，有優良的抗銹蝕能力，但將它移到海濱地區，在含有大量鹽份的海霧中，很快就會生銹了；而316鋼管則表現良好。因此，不是任何一種不銹鋼，在任何環境下都能耐腐蝕,不生銹的。

For example, 304 steel pipe has excellent corrosion resistance in a dry and clean atmosphere, but if it is moved to the coastal area, it will soon rust in the sea fog containing a lot of salt; And 316 steel pipe performs well. Therefore, not any kind of stainless steel can resist corrosion and rust in any environment.

不銹鋼卷簾門是靠其表面形成的一層薄而堅固細密的穩定的富鉻氧化膜（防護膜），防止氧原子的繼續滲入、繼續氧化，而獲得抗銹蝕的能力。一旦有某種原因，這種薄膜遭到了不斷地破壞，空氣或液體中氧原子就會不斷滲入或金屬中鐵原子不斷地析離出來，形成疏松的氧化鐵，金屬表面也就受到不斷地銹蝕。

The stainless steel roller shutter door is a thin, solid, fine and stable chromium rich oxide film (protective film) formed on its surface to prevent the continuous penetration and oxidation of oxygen atoms and obtain the anti-corrosion ability. Once for some reason, this kind of film is continuously damaged, oxygen atoms in air or liquid will continuously penetrate or iron atoms in metal will continuously separate out, forming loose iron oxide, and the metal surface will be constantly rusted.

這種表面膜受到破壞的形式很多，日常生活中多見的有如下幾種：

There are many forms of damage to this surface facial mask, and the following are common in daily life:

1.不銹鋼卷簾門表面存積著含有其他金屬元素的粉塵或異類金屬顆粒的附著物，在潮濕的空氣中，附著物與不銹鋼間的冷凝水，將二者連成一個微電池，引發了電化學反應，保護膜受到破壞，稱之謂電化學腐蝕。

1. There are dust containing other metal elements or adherents of different metal particles on the surface of the stainless steel roller shutter door. In the humid air, the condensate between the adherents and stainless steel will connect them into a micro cell, triggering an electrochemical reaction and damaging the protective film, which is called electrochemical corrosion.

2.不銹鋼卷簾門表面粘附有機物汁液（如瓜菜、面湯、痰等），在有水氧情況下，構成有機酸，長時間則有機酸對金屬表面的腐蝕。

2. Organic juices (such as melons and vegetables, noodle soup, sputum, etc.) adhere to the surface of the stainless steel roller shutter door, which constitute organic acids in the presence of water and oxygen, and will corrode the metal surface for a long time.

3.不銹鋼表面粘附含有酸、堿、鹽類物質（如裝修墻壁的堿水、石灰水噴濺），引起局部腐蝕。

3. The stainless steel surface adheres to substances containing acid, alkali and salt (such as alkali water and lime water splashing on the decoration wall), causing local corrosion.

4.在有污染的空氣中（如含有大量硫化物、氧化碳、氧化氮的大氣），遇冷凝水，形成硫酸、硝酸、醋酸液點，引起化學腐蝕。

4. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide and nitrogen oxide), when encountering condensed water, sulfuric acid, nitric acid and acetic acid liquid points will be formed, causing chemical corrosion.

以上情況均可造成不銹鋼表面防護膜的破壞引發銹蝕。面對問題，我們建議須經常對裝飾不銹鋼表面進行清潔擦洗，去除附著物，消除引發修飾的外界因素，需要用戶認真選擇有信譽廠家的產品。更多相關內容就來我們網站http://www.shaulmediation.com咨詢吧！

The above conditions can cause the damage of the protective film on the surface of stainless steel and lead to corrosion. In the face of problems, we suggest that the decorative stainless steel surface should be cleaned and scrubbed frequently to remove attachments and external factors that cause decoration. Users should carefully choose products from reputable manufacturers. For more information, please visit our website http://www.shaulmediation.com Consult!
