FAQ

What are the characteristics of different types of fin stock materials?

How is fin stock material produced?

1. Cleaning Process: After rolling and annealing the aluminum foil, a comprehensive cleaning process is carried out to remove all impurities and oil, ensuring that the aluminum foil substrate remains clean and uncontaminated. This step is crucial for providing a good surface condition for the subsequent coating application.

2. Pre-treatment Process: The surface of the cleaned aluminum foil undergoes a pre-treatment process to ensure that the coating adheres evenly to the substrate. This step improves the bonding strength between the aluminum foil and the coating, reducing the risk of coating peeling.

3. Coating Application: Special processes are used to apply hydrophilic or hydrophobic coatings evenly onto the surface of the aluminum foil. These coatings enhance the product's performance in heat exchangers. The uniformity of the coating directly impacts the performance of the fin stock, so this process is strictly controlled to ensure even coverage and the appropriate thickness of the coating.

4. Drying and Curing: After coating, the aluminum foil undergoes drying and curing to ensure strong adhesion and durability of the coating. The drying process is typically carried out under controlled temperature and humidity conditions to achieve the best coating effect, while curing enhances the mechanical properties of the coating, ensuring the fin stock material operates efficiently over the long term.

5. Quality Inspection: Finally, rigorous quality inspections are conducted, including tests for coating adhesion, corrosion resistance, and thickness. These checks include wiping tests, salt spray tests, etc., to verify the integrity and performance of the coating, ensuring that every batch of fin stock material meets high-quality standards.
