As an important transportation medium, Customized Shipping Containers need to withstand various weather and environmental tests during transportation and storage. In order to protect the appearance of the container during its service life, prolong its service life and improve its ability to resist various external factors, the container needs to be painted. Choosing a suitable painting method is one of the important factors affecting the quality and life of the container.

At present, the main spraying methods on the market are as follows: hand spraying, machine spraying, electrostatic spraying and fully automatic spraying technology, which will be introduced one by one below.

1. Hand spray

Hand spraying is a traditional method of painting for small jobs and simply painted surfaces. The process of hand spraying is relatively simple, just use a hand-held spray gun to spray the surface of the container, which is simple and easy. However, the shortcomings of hand spraying are also obvious. Because the spraying process is affected by the technical level and operating habits of the operators, the spraying effect is not stable, and different painters using the same paint may not be able to guarantee the same coating effect. In addition, manual deployment is required during spraying, and the efficiency is relatively low.

Two, machine spray

Machine spraying is an automatic spraying method, which is an upgraded version of the manual spraying method. It realizes the painting work by means of mechanization, and usually uses an automatic spraying system for construction, which can ensure the uniformity of the spraying effect. The advantages of machine spraying are not only high coating stability, but also high efficiency, which can adapt to large-scale coating production. However, the initial investment of machine spraying is relatively large, and more expensive coating equipment such as spraying equipment and nozzles need to be purchased.

3. Electrostatic spraying

Electrostatic spraying is an operation method that introduces a high-voltage electric field into a paint spraying machine, and at the same time, a spraying method in which the powder pigment is passed through the initial procedure in the high-voltage electric field to realize the spraying process. The environmental requirements for the customization of electrostatic spraying equipment are relatively strict, and the studio after operation needs to be thoroughly cleaned and disinfected to ensure that no respiratory-related diseases occur. The coating effect of electrostatic spraying is relatively uniform and beautiful, and can be well guaranteed in terms of surface quality, adhesion, corrosion resistance and wear resistance. The disadvantage of electrostatic spraying is that the cost of equipment is high, and it is difficult to master electrostatic spraying. Once an operation error occurs, it will lead to obvious defects in the quality of the finished product.

4. Fully automatic spraying technology

The fully automatic spraying technology is the combination of precision control technology and computer network technology to realize the automatic painting process of container spraying. From the beginning of the painting plan to the completion of the whole process of automatic operation, it integrates painting design, quality control, chemical measurement, automatic cleaning, etc. A number of new technologies realize the fast, accurate and error-free coating of Containers through automatic control, which is a relatively advanced coating process at present. Compared with the previous operation mode, the fully automatic spraying process has been innovated. Its coating efficiency is higher, the quality index is higher, the management is more convenient and the requirements for workers are lower. It can not only realize the processing of mainstream colors and fancy patterns, but also can Realize a more personalized coating process.

In short, when choosing a painting method, it is not only necessary to consider factors such as the strength of the company, spraying needs, product quality requirements, and the success of the painting process, but also to choose according to the actual situation of the company. After comprehensive consideration of various factors, a more suitable container painting method can be selected to improve the spraying effect, prolong the service life, maximize the service for container painting, and increase profits for the enterprise.
