Exploring Dalian Coating Technology: An Artistic Journey from Substrate Processing to Topcoat Presentation

Dalian painting technology is like a carefully arranged artistic journey, starting from substrate processing and gradually laying out better coating paintings.

Substrate processing is the cornerstone of this journey. Different processing methods are required for substrates made of different materials, such as metal, wood, or plastic. Metal substrates may undergo processes such as rust removal and phosphating to eliminate surface rust and form a phosphating film, enhancing coating adhesion; Wood needs to be polished flat, with burrs and defects removed. Sometimes, it also needs to be treated with insect and anti-corrosion measures. This step is like leveling the ground for subsequent artistic creation, ensuring that every color can firmly take root.

The application of primer is a crucial stroke in the journey. Primer is like an understated base layer, providing basic protection and adhesion support for the entire coating system. It can fill the tiny pores of the substrate, blocking the penetration of water vapor and corrosive substances. When preparing the primer, it is necessary to accurately control its viscosity and composition ratio to ensure that it evenly covers the substrate and builds a stable "foundation" for subsequent coatings. For example, in industrial machinery painting, high-quality primers can effectively extend the service life of equipment and resist the erosion of harsh environments.

The intermediate coating is like a transitional tone and texture in a painting. It further modifies the surface of the substrate, increases the thickness and flatness of the coating, and enhances the overall fullness and three-dimensional sense of the coating. In the automotive painting process, the construction requirements for intermediate coatings are extremely high. Through multiple spraying and fine polishing, the surface of the car body is made as smooth as a mirror, laying a solid foundation for the wonderful presentation of the topcoat.

The presentation of the topcoat is undoubtedly the climax of this artistic journey. Topcoat endows objects with brilliant colors and unique luster, making them stand out. Whether it's the stylish appearance of cars or the elegant color tones of building exteriors, they all rely on topcoats to showcase individuality. Strict control of environmental temperature and humidity, as well as precise control of spray gun distance, angle, and spraying speed, are key factors in ensuring the uniformity, smoothness, and bright color of the topcoat during the spraying process.

From substrate treatment to topcoat presentation, Dalian coating technology has completed a magnificent transformation from protection to beautification with its rigorous process steps and fine operational requirements, turning ordinary objects into exquisite works that combine practical value and artistic charm.
