In daily life, stainless steel screws are common fasteners. During use, rust is a common phenomenon and 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 main points of use in the process of using stainless steel screws: 1. The surface of stainless steel screws adheres to organic juice (such as melon, vegetable, noodle soup, sputum, etc.), which will form organic acid under the condition of water and oxygen. Time is the corrosion of organic acids on the metal surface.
2. 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, triggering an electrochemical reaction and destroying the protective film, which is called electricity Chemical corrosion.
3. 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 in contact with condensed water, causing chemical corrosion.
4. The surface of stainless steel adheres to acid, alkali, and salt substances (such as alkaline water and lime water splashing on the decoration wall), causing local corrosion.
