Container, as the core tool of international logistics, often faces various complex environmental conditions. This has made its corrosion problem increasingly watched. So, what are the factors of container corrosion?

First of all, we must understand that there are two main types of container corrosion: chemical corrosion and electrochemical corrosion. Chemical corrosion is mainly due to a chemical reaction of the gas or liquid medium and the metal surface, which generates compounds, resulting in corrosion of the metal surface. The electrochemical corrosion is due to the difference in potential on the metal surface, which reacts with another metal in the electrolyte, which causes one of the metals to be corroded.
There are three main factors that affect container corrosion:
The impact of metal materials itself: The corrosion resistance of different metal materials is different. For example, the corrosion resistance of stainless steel is stronger than that of ordinary steel. Therefore, it is the key to choose the material with strong corrosion resistance when making a container.
The impact of ambient temperature and humidity: The environment of high temperature and high humidity will accelerate the corrosion process of metal. In addition, temperature changes will also have the effect of heat and swollen and contracted metal, which will affect the protective layer of the metal surface and accelerate corrosion.
Effects of the composition, concentration and movement speed of the corrosive media: For example, seawater contains a variety of corrosive medias, such as sodium chloride, calcium chloride, etc. These substances accelerate the corrosion of metal. In addition, the flow rate of the medium on the metal surface will also affect the speed of corrosion. The faster the flow velocity, the more severe the corrosion.
In order to reduce the corrosion of the container, we should pay attention to these influencing factors and take corresponding measures. For example, selective materials with strong corrosion resistance, maintenance of regular anti -corrosion coating, and avoid long -term exposure to high temperature and high humidity environments. Only in this way can we ensure the service life and safety of the container.
