How to evaluate the quality and durability of aluminum product surface oxidation?
1. Coating thickness measurement
Coating thickness refers to the actual thickness of the oxide layer or coating on the surface of aluminum products. This not only determines the corrosion resistance of aluminum products, but also affects the appearance quality, mechanical properties and chemical stability of the product. A coating that is too thin may not provide sufficient protection, causing aluminum products to corrode rapidly in harsh environments; while a coating that is too thick may increase costs and even affect the performance of the product. Use appropriate instruments to measure the coating thickness to ensure that the coating on the surface of aluminum products meets the corresponding standards.
2. Coating uniformity inspection
Coating uniformity has an important impact on the appearance quality and corrosion resistance of aluminum products. Check whether the coating is evenly distributed on all parts of the surface of the aluminum product, and pay attention to the unevenness of the coating thickness. In hard oxidation treatment, special attention should be paid to whether the oxide film is uniform.
3. Coating tightness inspection
Coating tightness refers to the adhesion ability of the coating to the surface of the aluminum product, which is an important factor affecting the durability of aluminum products. Observe whether the coating has peeling, blistering, etc. Use a smoother hard object to scratch the surface of the industrial aluminum profile. A white mark will appear on the qualified surface, but it can be wiped off by hand.
4. Oxidation degree detection
The oxidation degree refers to the ratio of the thickness of the oxide layer to the thickness of the aluminum substrate, which is an important indicator for evaluating the quality of the oxide layer of aluminum profiles. The national standard GB/T5237.2 stipulates that the thickness of the oxide layer of thick-oxygen aluminum should be greater than or equal to 10μm, and the oxidation degree should not be less than 8μm/m; the thickness of the oxide layer of medium-oxygen aluminum should be greater than or equal to 8μm, and the oxidation degree should not be less than 6μm/m; the thickness of the oxide layer of thin-oxygen aluminum should be greater than or equal to 5μm, and the oxidation degree should not be less than 3μm/m.
5. Corrosion resistance evaluation
Corrosion resistance is one of the important criteria for evaluating the surface oxidation quality of aluminum products. The corrosion resistance of aluminum products can be evaluated by simulating the actual use environment or accelerating corrosion tests.
6. Comprehensive evaluation
In addition to the above specific evaluation indicators, it is also necessary to comprehensively consider the influence of factors such as the chemical composition, surface state, oxidation time and oxidation temperature of aluminum products on the quality of the oxide layer. In the actual production process, the composition, concentration and temperature of the electrolyte should be strictly controlled, and appropriate anodizing methods should be adopted to ensure that a dense oxide layer is formed on the surface of the aluminum product to achieve the best anti-corrosion performance.
In summary, the evaluation of the quality and durability of the surface oxidation of aluminum products requires comprehensive consideration of coating thickness, uniformity, tightness, oxidation degree, corrosion resistance, etc. At the same time, it is also necessary to combine specific production conditions and product requirements, and adopt appropriate quality control and testing methods to ensure that the quality and durability of the surface oxidation of aluminum products meet the standards.
