What advantages does the oxidation treatment of the aluminum cover surface bring to Aluminum Emulsion Jar?

The oxidation treatment of the aluminum cover surface of the Aluminum Emulsion Jar significantly enhances its heat resistance by forming a dense aluminum oxide film. The aluminum oxide film has a high melting point and thermal stability, and can effectively resist thermal stress in high temperature environments. During high-temperature storage, transportation or use, this film prevents the aluminum cover from softening, deforming or even melting due to heat, thereby ensuring that the sealing and structural integrity of the emulsion tank are not affected. This feature is particularly important for emulsion products that need to be stored or transported under specific high temperature conditions, which can ensure the quality stability of the product in high temperature environments.

The chemical stability of the aluminum oxide film gives the aluminum cover excellent corrosion resistance. The film can isolate the aluminum substrate from direct contact with the external corrosive medium, thereby preventing the aluminum cover from electrochemical corrosion or chemical corrosion. This feature significantly extends the service life of the aluminum cover and avoids problems such as sealing failure, appearance damage or emulsion contamination caused by corrosion. For emulsion products that need to be stored for a long time, oxidation treatment can effectively maintain the sealing and product quality of the emulsion tank.

The dense structure of the aluminum oxide film is the key to reducing product oxidation. The film can effectively block the penetration of oxidants such as oxygen and moisture into the emulsion, thereby delaying the oxidation and deterioration process of the emulsion. For emulsion products containing easily oxidized ingredients, oxidation treatment can significantly maintain the stability, color, aroma and efficacy of the product and extend the shelf life of the product.

The aluminum oxide film formed by oxidation treatment has a much higher hardness than the aluminum substrate and has good wear resistance. In daily use, this film can resist scratches, wear and impact, maintaining the integrity and beauty of the appearance of the aluminum cover. At the same time, the improvement of wear resistance also avoids the risk of sealing failure or product contamination caused by surface damage. For emulsion cans that need to be opened and closed frequently, oxidation treatment can significantly improve their durability and reliability.

Oxidation treatment provides a rich selection of colors and glosses for aluminum covers, thereby optimizing the appearance and decorativeness of the product. By controlling the process parameters, aluminum oxide films of different colors and glosses can be obtained to meet the aesthetic needs of different customers. This diverse appearance selection not only enhances the visual appeal of the product, but also enhances the market competitiveness of the product. At the same time, oxidation treatment can also achieve different surface effects such as matte and gloss, further enriching the appearance of the product.

No heavy metals or harmful chemicals are used in the oxidation process, and the aluminum oxide film itself is non-toxic and harmless. This feature makes the oxidized aluminum cover in line with the concept of green environmental protection. The aluminum cover can be recycled and reused, reducing environmental pollution and waste of resources. At the same time, the corrosion resistance of the aluminum oxide film also reduces the risk of emulsion leakage caused by damage to the aluminum cover, further protecting the environment.
