How to Determine the Quality of Solar Aluminum Profiles:
1. Inspection of Markings: Check whether the solar aluminum profiles and their packaging are clearly marked with the product standard code and production license number. Proper labeling is an indicator of quality and compliance.
2. Surface Quality: The surface of the solar aluminum profile should be clean, smooth, and free from cracks, peeling, corrosion, or bubbles. It should also not show signs of corrosion spots, electric burns, black spots, or oxide film peeling. These defects can affect both the appearance and performance of the material.
3. Oxide Film Thickness: The oxide layer on solar aluminum profiles is created through anodizing, which provides protection and enhances aesthetics. This thickness can be measured using an eddy current thickness gauge, ensuring it meets the required standards for durability and longevity.
4. Sealing Quality: A common on-site test involves the acid leaching method. If the sealing is poor, visible traces will remain after the test. The more noticeable the marks, the lower the quality of the sealing, which can lead to reduced corrosion resistance over time.
5. Corrosion Resistance: The drop alkali test is a simple visual method to assess the corrosion resistance of the oxide film. By observing the droplets until bubbling occurs and the film is penetrated, you can determine its strength. However, this test is more accurate when conducted in a controlled laboratory environment, especially during summer when conditions are more favorable.
