The painting process and key points of container house manufacturers
1、 Preparation work
Before starting the painting work, a series of preparatory work is required. Firstly, the container needs to be moved to the painting area, and then the surface of the container needs to be cleaned and degreased to ensure cleanliness. Next, drying treatment is required to ensure that the surface is completely dry and free from any moisture or humidity.
2、 Surface treatment
The important step is surface treatment, which is the key to ensuring the smoothness of the container surface and the adhesion of the paint. Surface treatment mainly involves removing surface rust and corrosive substances to achieve a smooth effect. Common methods include wire brush removal, chemical corrosion, etc. After surface treatment, sandblasting is also required to ensure a smooth and even surface.
3、 Primer spraying
The spraying of primer is a crucial process. Before spraying the primer, it is necessary to dilute and stir it first. The viscosity of primer spraying should be within a reasonable range, and samples and adjustments should be made before spraying to ensure uniform spraying. After the primer solidifies, it needs to be polished to ensure a smooth and even surface.
4、 Topcoat spraying
Topcoat spraying is the final step, which needs to be carried out after the primer spraying is completed. The spraying of topcoat also requires dilution and maintaining a certain viscosity. During the spraying process, it is necessary to pay attention to whether the spraying thickness is consistent to avoid peeling and cracking. After the spraying is completed, it needs to be dried, polished, and cleaned.
Only perfect electrostatic powder coating combined with baking paint technology can ensure the service life of container houses and avoid aging of container houses
