From an environmental point of view, different surface treatments will have different levels of impact on the environment. The following is a brief assessment of the environmental performance of various surface treatments:

  • Advanced anodizing: This is a relatively environmentally friendly treatment because it does not require the use of harmful chemicals and does not produce large amounts of waste during the treatment process. Anodizing mainly uses the electrochemical principle to form an oxide film on the surface of the aluminum plate, so it has less impact on the environment.
  • Laser etching: Laser etching is also a relatively environmentally friendly treatment. It uses laser technology to create patterns or textures on the surface of aluminum plates without the use of any chemicals. The laser etching process produces less waste and has less impact on the environment.
  • Chemical coating: Chemical coating may require the use of some chemicals, which may have a certain impact on the environment during the treatment process. In addition, wastewater may be generated during the chemical coating process, which requires proper treatment before it can be discharged.
  • Vacuum coating: Vacuum coating is usually carried out in a vacuum environment and does not use harmful substances, so it is relatively environmentally friendly. However, some energy-intensive equipment may be used during the coating process, which will increase energy consumption to a certain extent.

In summary, from an environmental perspective, advanced anodizing and laser etching may be more environmentally friendly surface treatments because they do not use harmful chemicals and produce less waste. However, the specific environmental protection also needs to consider the actual operation of the process of energy consumption, wastewater treatment and other factors. When selecting the surface treatment method, it is recommended to consider environmental protection, performance requirements and cost budget, and choose the most suitable treatment method.

From the point of view of safety and corrosion resistance, different surface treatments have different advantages. The following is an assessment of the various surface treatments:

  • Advanced anodizing: This is a very corrosion-resistant treatment. By forming a thick and uniform oxide film, advanced anodizing can significantly improve the corrosion resistance of aluminum sheets. In addition, because the formation of the oxide film is naturally generated on the surface of the aluminum plate, it has good adhesion and stability and is relatively safe.
  • Chemical coating: Chemical coating, especially the use of good corrosion resistance such as nickel, chromium, and other metals for coating, can also provide high corrosion resistance. However, the chemicals used in the chemical coating process may present certain safety risks and require proper disposal of wastewater and waste.
  • Vacuum coating: Vacuum coating can form a uniform and dense metal or non-metal film on the surface of the aluminum plate, which can also improve the corrosion resistance of the aluminum plate. Because the coating process is carried out in a vacuum environment, no harmful substances are used, so it is relatively safe.
  • Laser etching: Laser etching is mainly used for the creation of surface patterns or textures, with limited improvement in corrosion resistance. However, as a physical treatment method, it does not involve the use of harmful chemicals, so it is relatively safe.

In summary, from the point of view of safety and corrosion resistance, advanced anodizing and vacuum coating may be a better choice. The oxide film formed by advanced anodizing has good stability and corrosion resistance, and the vacuum coating can form a uniform and dense protective film on the surface of the aluminum plate. However, the specific choice of surface treatment method needs to be determined according to the specific needs of the product and the use environment.

The surface treatment classification of the improved 3105 alloy aluminum sheet plate mainly includes the following:

  • Advanced anodizing: This is an anodizing treatment that uses a special process. Compared with traditional anodizing, advanced anodizing can form a thicker, more uniform, and colorful oxide film on the surface of the improved 3105-grade alloy aluminum sheet, which not only enhances its corrosion resistance but also improves the hardness and wear resistance of the surface, while also increasing its decorative.
  • Laser etching: The use of laser technology to form a specific pattern or texture on the surface of the modified 3105 aluminum alloy plate. This treatment not only increases the beauty of the alloy aluminum sheet 3105 but also gives it a unique texture so that it has a wide range of applications in the field of decoration and signage.
  • Chemical coating: By forming a special layer of chemical coating on the surface of the improved 3105 aluminum alloy plate, such as nickel, chromium, etc., it can enhance its wear resistance, corrosion resistance or electrical conductivity. This treatment allows different coating materials to be selected according to specific needs to improve performance.
  • Vacuum coating: In a vacuum environment, through physical evaporation or sputtering, a layer of metal or non-metal film is formed on the surface of the improved 3105 aluminum alloy plate, such as gold, silver, chromium, etc. This treatment can increase the aluminum plate’s beauty and functionality and improve the surface’s hardness and wear resistance.

These surface treatment options enable the modified 3105 aluminum alloy plate to meet the needs of more specific scenarios and to obtain a wide range of applications in industrial and civil fields. The treatment method choice must be determined according to the use environment and product performance requirements.
