不锈钢花纹板的其表面形成一层非常薄、牢固、稳定的富铬氧化膜（保护膜），防止氧原子的不断渗透和氧化，从而获得防锈能力。一旦膜层因某种原因不断被破坏，空气或液体中的氧原子会不断渗入或金属中的铁原子会不断析出，形成疏松的氧化铁，金属表面就会不断被腐蚀。这种表面膜的损坏形式有很多种，日常生活中常见的有以下几种：
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、不锈钢表面有灰尘或含有其他金属元素的异质金属颗粒沉积。在潮湿的空气中，沉积物和不锈钢之间的冷凝水将两者连接成一个微型电池，从而引发电化学反应。 ，保护膜被破坏，称为电化学腐蚀。
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、有机汁液（如蔬菜、面汤、痰液等）附着在不锈钢板表面。在水和氧气存在的情况下，形成有机酸，有机酸长期腐蚀金属表面。
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不锈钢花纹板多少钱表面附着含酸、碱、盐的物质（如装饰墙溅出的碱水、石灰水），造成局部腐蚀。
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、在受污染的空气中（如含有大量硫化物、碳氧化物、氮氧化物的大气），遇冷凝水会形成硫酸、硝酸、醋酸液点，引起化学腐蚀。
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.
