House Container accessories are the products of various units and House Containers that constitute the whole House Container. There are many kinds of House Container Accessories. House Containers can be divided into small ones, large ones and super high ones, among which 20GP, 40GP and 40HQ are more common. In recent years, housing container accessories are also developing rapidly. After understanding some simple concepts of housing container accessories, we should also pay attention to some knowledge about the rust prevention of housing containers, which is necessary for us to use housing containers for a longer time. Before talking about the rust prevention of housing containers, let's understand some concepts and data. The metal corrosion process is generally carried out through two ways: chemical corrosion and electrochemical corrosion.

Chemical corrosion: corrosion caused by direct chemical reaction between metal surface and surrounding medium. Such as metal corrosion caused by acid rain and acid mist.

Electrochemical corrosion: corrosion caused by electrode reaction when metal materials (alloy or impure metal) contact with electrolyte solution. Such as slow corrosion of iron products in humid environment. According to statistics, the annual steel loss caused by metal corrosion accounts for about 10%~20% of the steel output of that year. It also means that the corrosion rate of steel (calculated by year) accounts for about 10%~20% of the overall structure.

In view of the different corrosion processes of metals, two common anti-corrosion measures are: one is the isolation of chemical corrosive substances (such as acid rain and acid mist), and the other is the electrochemical protection of target metals (such as placing metals with stronger metallicity close to the metal to be protected, so that metals with stronger metallicity can replace the metal to be protected as the cathode of the primary battery. First, oxidation occurs to protect the target metal). Besides, electrochemical corrosion is the main factor in the corrosion process of housing containers. Because chemical corrosion is well prevented, the anti rust finish * can play a good isolation role. However, in the transportation process of housing containers, it is inevitable that small areas of paint film will be damaged due to scratches and other reasons. The corrosion process at the damaged parts of paint film is dominated by electrochemical corrosion, and the corrosion process dominated by electrochemical corrosion is a gradually accelerated process after the formation of rust spots. At this time, the protection of the top coat to the damaged parts of the box is basically zero, so the prevention of electrochemical corrosion becomes the top priority in the process of anti-corrosion of housing containers. Accessories are the products of each unit constituting the whole house container and the house container. There are many kinds of house container accessories.
