Although stainless steel is called stainless steel, it is definitely not rust-free. When using stainless steel fasteners, we must know how to avoid product rust. In the process of use, rust is a common phenomenon, and it is also an annoying thing for us. This will not only affect the aesthetics, but also affect the performance of stainless steel screws.
Therefore, we must pay attention to the key points in the use of stainless steel screws. The following are four points summarized by the editor for your reference:
1. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide), it will form sulfuric acid, nitric acid, and acetic acid liquid spots when encountering condensed water, causing chemical corrosion. 2. The surface of the stainless steel screw adheres to the organic juice (such as melon, vegetable, noodle soup, sputum, etc.), which forms organic acid in the presence of water and oxygen, and the organic acid will corrode the metal surface for a long time.
3. The attachment of dust or foreign metal particles, in the humid air, the attachment and the condensed water of the stainless steel screw, connect the two to form a micro battery, which triggers an electrochemical reaction, and the protective film is destroyed, which is called electricity. Chemical corrosion.
4. The surface of stainless steel adheres to containing acid, alkali, and salt substances (such as alkaline water and lime water splashing on the decoration wall), causing local corrosion.
