    引發(fā)不銹鋼花紋板表面膜損壞導致生銹的原因是什么?

    作者:山東超光耀金屬材料有限公司 來(lái)源:http://www.ltcsh.com 日期:2022/5/31 11:59:31

    不銹鋼花紋板的其表面形成一層非常薄、牢固、穩定的富鉻氧化膜(保護膜),防止氧原子的不斷滲透和氧化,從而獲得防銹能力。一旦膜層因某種原因不斷被破壞,空氣或液體中的氧原子會(huì )不斷滲入或金屬中的鐵原子會(huì )不斷析出,形成疏松的氧化鐵,金屬表面就會(huì )不斷被腐蝕。這種表面膜的損壞形式有很多種,日常生活中常見(jiàn)的有以下幾種:

    A very thin, firm and stable chromium rich oxide film (protective film) is formed on the surface of the stainless steel checkered plate to prevent the continuous penetration and oxidation of oxygen atoms, so as to obtain the anti rust ability. Once the film layer is continuously damaged for some reason, the oxygen atoms in the air or liquid will continue to penetrate or the iron atoms in the metal will continue to precipitate, forming loose iron oxide, and the metal surface will continue to be corroded. There are many forms of damage to this facial mask, and the following are common in daily life:

    1、不銹鋼表面有灰塵或含有其他金屬元素的異質(zhì)金屬顆粒沉積。在潮濕的空氣中,沉積物和不銹鋼之間的冷凝水將兩者連接成一個(gè)微型電池,從而引發(fā)電化學(xué)反應。 ,保護膜被破壞,稱(chēng)為電化學(xué)腐蝕。

    1. Dust or heterogeneous metal particles containing other metal elements are deposited on the surface of stainless steel. In humid air, condensate between sediment and stainless steel connects them into a miniature battery, which leads to a chemical reaction, The damage of protective film is called electrochemical corrosion.

    2、有機汁液(如蔬菜、面湯、痰液等)附著(zhù)在不銹鋼板表面。在水和氧氣存在的情況下,形成有機酸,有機酸長(cháng)期腐蝕金屬表面。

    2. Organic juice (such as vegetables, noodle soup, sputum, etc.) is attached to the surface of stainless steel plate. In the presence of water and oxygen, organic acids are formed, which corrode the metal surface for a long time.

    3、304不銹鋼花紋板多少錢(qián)表面附著(zhù)含酸、堿、鹽的物質(zhì)(如裝飾墻濺出的堿水、石灰水),造成局部腐蝕。

    3. The surface of 304 stainless steel checkered plate is attached with substances containing acid, alkali and salt (such as alkali water and lime water splashed from the decorative wall), causing local corrosion.

    4、在受污染的空氣中(如含有大量硫化物、碳氧化物、氮氧化物的大氣),遇冷凝水會(huì )形成硫酸、硝酸、醋酸液點(diǎn),引起化學(xué)腐蝕。

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