Treatment process before spraying curved aluminum veneer

Treatment process before spraying curved aluminum veneer

1. Overview

Spraying curved aluminum veneer is a beautiful and practical building decoration material. Before spraying, aluminum veneer needs to undergo a series of rigorous treatment processes to ensure its surface quality, corrosion resistance and long-term stability. This article will detail the processing process before spraying the curved aluminum veneer.

Preparation of 2. materials

First of all, high-quality aluminum veneer material is selected to ensure that it has good physical properties and corrosion resistance. At the same time, prepare the required spraying equipment, paint, auxiliary materials, etc.

3. surface treatment

1. Cleaning: Clean the surface of the aluminum veneer to remove oil, dust and other impurities to ensure that the surface is clean and free of impurities.
2. Grinding: Grind the surface of the aluminum veneer to remove defects such as scratches and bumps to make the surface smoother.
3. Chemical treatment: through chemical methods, such as acid washing or alkali washing, further remove the impurities on the surface of the aluminum veneer and improve the adhesion of the coating.

4. design spraying scheme

According to the actual demand, design the spraying scheme, including the color, thickness and spraying mode of the paint. Ensure that the sprayed aluminum veneer achieves the desired effect.

5. pretreatment check

Before spraying, check the surface treatment of aluminum veneer to ensure that the surface is clean, free of impurities and defects. If problems are found, deal with them in time to ensure the spraying quality.

6. formal spraying

According to the design of the spraying scheme, the formal spraying. Ensure that the coating is uniform and consistent in thickness to avoid flowing and leakage.

7. quality inspection
