What is the oxidation process for surface treatment of empty aluminum lipstick tubes?

The oxidation process of surface treatment of empty aluminum lipstick tubes is mainly a process that forms a dense oxide film on the surface of the aluminum tube through chemical or electrochemical methods. This process can significantly improve the corrosion resistance and decorative properties of aluminum tubes, and is a very important part of the surface treatment of aluminum products.
The aluminum tube oxidation process is mainly based on the chemical reaction of aluminum and oxygen. During the oxidation process, the surface of the aluminum tube reacts chemically with oxygen in the air (or oxygen in the oxidation tank) to form a dense aluminum oxide film. This film can effectively protect the aluminum pipe from corrosion by the external environment, such as moisture, acid and alkali and other corrosive substances, thus improving its corrosion resistance and service life.
First, the aluminum tube is cleaned and degreased to remove oil, impurities and scale on the surface. This step is key to ensuring the quality of the subsequent oxidation process, because any contaminants remaining on the surface of the aluminum tube may affect the formation and quality of the oxide film. Put the pretreated aluminum tube into an oxidation tank, and control parameters such as bath liquid composition (such as sulfuric acid, oxalic acid, etc.), temperature and time to form a uniform oxide film on the surface of the aluminum tube. This step is the core of the oxidation process and requires precise control of various parameters to obtain ideal oxide film thickness and performance.
In order to improve the corrosion resistance and decorative properties of the oxide film, sealing treatment is usually required. The sealing agent can chemically react with the micropores in the oxide film to make the film layer denser, thereby improving its corrosion resistance and decorative effect. According to needs, the oxidized aluminum tube can be colored, spray-painted and other post-processing to achieve better decorative effects. For example, the oxide film can be made into various colors through the dyeing process to meet the individual needs of customers.
The oxide film has excellent corrosion resistance and can protect the aluminum pipe from erosion by the external environment. Through post-processing processes such as dyeing, the oxide film can show rich colors and improve the aesthetics of the product. The oxide film has a certain hardness and can increase the wear resistance and service life of the aluminum tube. Compared with other surface treatment processes, the oxidation process is relatively environmentally friendly and causes less environmental pollution.
The aluminum tube oxidation process is widely used in various fields, including cosmetic packaging (such as lipstick tubes), auto parts, electronic product casings, etc. Not all types of aluminum are suitable for oxidation treatment, so the appropriate aluminum needs to be selected based on the specific needs of the product. Various parameters of the oxidation process need to be precisely controlled to obtain ideal oxide film thickness and performance. Post-processing, such as coloring, spray painting, etc., is performed according to the specific needs of the product to improve the aesthetics and performance of the product.
The oxidation process of empty aluminum lipstick tubes is an important surface treatment technology that can significantly improve the corrosion resistance and decorative properties of the product. In practical applications, it is necessary to select appropriate aluminum materials and process parameters according to the specific needs of the product, and perform necessary post-processing to meet the individual needs of customers.
