Production process of color-coated coils

The production process of color-coated coils has a great impact on their quality. Consumers can check the production process of color-coated coils through the following aspects:

1. Coating technology: High-quality color-coated coils should adopt high-quality coating technology, such as double coating and double baking, high molecular ester and other advanced technologies.

2. Drying temperature: The drying temperature should be controlled within the appropriate range. Too high or too low drying temperature will affect the quality of the coating.

3. Pickling process: Advanced pickling process should be used in the production process of color-coated coils to remove oxides and impurities on the surface of the substrate.

4. Surface treatment: The surface treatment of color-coated coils should adopt degreasing, rust removal and other processes to ensure strong coating adhesion.
