In daily life, stainless steel screws are common fasteners. During 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:

1. Adhesive juice on the surface of stainless steel screws (such as melons, vegetables, noodle soup, sputum, etc.), in the presence of water and oxygen, constitutes acid, and the acid will corrode the metal surface for a long time.

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 is adhered to contain acid, alkali, and salt substances (such as alkaline water and lime water splashing on the decoration wall), causing local corrosion.
