Why Does Stainless Steel Surface Rust- Parking Lot Management System

Stainless steel access gate, stainless steel lifting column, stainless steel rotary gate... Why does the stainless steel surface rust? The glittering surface looks spotless, but it still rusts after a long time. This is because there is metal dust on its surface that we can't see with our naked eyes. Although we can't see it carefully, it actually exists, When these metal attachments encounter humid air, they will cause a series of chemical reactions. Even if there is a protective film on the surface of the rigid body, it is easy to be eroded, resulting in the destruction of the protective film and rust. This phenomenon is called electrochemical corrosion, which will lead to the rust of stainless steel channel gate, stainless steel lifting column and stainless steel rotary gate without maintenance. Many people think that stainless steel products will not rust because it has super corrosion resistance, especially for some types of steel. Even if it is placed in seawater or humid environment, it can maintain long-term stability and will not rust, but it is not completely the case in life, Many stainless steel products will be rusty under complex environment or improper maintenance, which makes people doubt whether its quality is qualified. Stainless steel channel gate, stainless steel lifting column and stainless steel transfer gate will rust without maintenance. Is this the case? Where is the reason? If the stainless steel access gate, stainless steel lifting column and stainless steel turnstile are installed in advance, the stainless steel access gate, stainless steel lifting column and stainless steel turnstile are splashed with alkaline water or lime water, which will also lead to the corrosion of the steel body, as well as nitrogen Sulfur and other unclean gases surround the steel surface for a long time, and spotted corrosion will also appear over time. This corrosion is called chemical corrosion. If these impurities are very strong, what will happen if soup or other seemingly very soft liquids fall on the steel surface without cleaning? The actual situation is that they will also cause corrosion on the steel surface, Therefore, the seemingly strong stainless steel can not withstand the subtle damage, resulting in the rust of stainless steel channel gate, stainless steel lifting column and stainless steel transfer gate without maintenance.
