Customized Shipping Container is a commonly used freight tool in the field of cargo transportation. It has the advantages of large capacity, long service life, and transportation safety, and has been widely recognized and popularized. However, with the transportation and storage of Containers, the corrosion problem on the surface of containers has gradually become prominent. Therefore, in order to maintain the quality and service life of the container, anti-rust treatment for sea containers is very important.

1. Selection of anti-rust coating

Anti-rust coatings are the main means of anti-rust measures. Anti-rust coatings for Customized Shipping Containers should generally choose anti-rust coatings such as external anti-corrosion paints, internal sealant coatings, and high-temperature luminous coatings. These anti-rust coatings have different uses and characteristics. In actual production, different coatings should be selected according to different areas of the container.

1. External anti-corrosion paint: As one of the common anti-rust paints, its main components are zinc-containing, aluminum-containing, and fluorine-containing resins. Widely used in climbing protection, hull and deck protection, bow and stern protection, etc. This kind of coating has good adaptability, wall adhesion and weather resistance. At the same time, it can effectively prevent container corrosion in different shipping environments.

2. Base-sealing paint: This kind of paint generally does not need to be used with a primer. Before use, just paint the surface of the container directly. It has the advantages of water resistance, good adhesion and long service life. But its anti-rust effect will be better used with primer.

3. High-temperature luminescent paint: This paint is widely used in container signs, truck and cargo signs and other related positions. It does not change color at high temperature, has good adhesion, and has a pleasing color, and can remind people to pay attention to safety. At the same time, in extreme darkness, the high-temperature luminescent paint has sufficient lighting ability.

2. Anti-rust spraying

In addition to paint treatment, anti-rust spraying is also one of the important anti-rust measures for customized shipping containers. Antirust spraying mainly uses fungicides or other carbonyl dihydroxylamine mixtures. In the past, smearing paint was widely used, but it was gradually replaced by spraying process in the process of popularization. Anti-rust spraying not only has anti-rust effect, but also is harmless to the environment and human body, which is of great help to environmental safety.

3. Container powder coating

Container powder spraying is similar to the previous anti-rust spraying method, but different from the former, it uses liquid paint to deposit and spray powder. The advantage of this method is that all raw materials are pure natural and harmless substances. After spraying, a protective film equivalent to a metal layer is formed to prevent rainwater, dust and other landing objects from entering the surface of the container from the pores.

4. Anti-rust cleaning of containers

Anti-rust cleaning of containers can effectively keep the surface of containers clean. Sterilization cleaning is a very important step before anti-rust coating is applied. The surface of the container should first be cleaned to remove dirt and chemical corrosion from the surface. The corrosion, rust and paint on the surface of the old container should be effectively removed, and the container seal should be cleaned. After cleaning, carry out protective treatment in order to achieve a win-win effect.

In short, there are many anti-rust solutions for Customized Shipping Containers. By choosing different anti-rust measures, the container can be kept in good condition for a long time, the service life of the container can be enhanced, and the production and transportation efficiency can be improved. In actual operation, it can be judged and implemented in light of specific circumstances.
