How to prevent rust from stainless steel screws

In daily life, stainless steel screws are common fasteners. During use, rust is a common phenomenon and it is also a trouble 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 use points in the process of using stainless steel screws: 1. The surface of stainless steel screws adheres to organic juice (such as melon, noodle soup, glutinous rice, etc.), in the case of water and oxygen, constitutes organic acid, long Time is the corrosion of the metal surface by organic acids.

2, the attachment of dust or heterogeneous metal particles, in the humid air, the condensate of the attachment and the stainless steel screw, the two are connected into a micro-battery, causing an electrochemical reaction, the protective film is destroyed, called the electricity Chemical corrosion.

3. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, nitrogen oxide), in the case of condensed water, sulfuric acid, nitric acid, acetic acid liquid point is formed, causing chemical corrosion.

4. The surface of the stainless steel adheres to acid, alkali and salt substances (such as alkali water and lime water splashing on the wall), causing local corrosion.
