What should do if blackening occurs during the oxidation process of aluminum profiles
Aluminum profile anodizing machine function:Aluminum profile anodizing machine plant is mainly used to treat the surface of aluminum profiles through oxidation process, generating aluminum oxide protective layer to enhance their corrosion resistance, wear resistance, insulation and decorative properties.
1,Generating aluminum protective layer: By electrolytic process, a uniform and dense aluminum film is formed on the surface of aluminum profiles, significantly enhancing corrosion resistance and preventing substrate oxidation.
2,Improve wear resistance: The oxide film has high hardness and can effectively resist scratches and wear, extending its service life.
3,Enhance insulation: The oxide film is non-conductive and suitable for scenarios such as electronic devices that require insulation.
4,Improving Decoration: Achieving a colorful appearance through coloring techniques to enhance the aesthetic appeal of the product.
5,Optimize spray painting effect: enhance surface adsorption capacity, making the paint film more uniform and durable
Design features about anodizing machine Plant:
1, full automatic oxidation machine
2,semi automatic oxidation machine
3,manual oxidation machine
What should do if blackening occurs during the oxidation process of aluminum profiles?
The blackening phenomenon occurs during the oxidation process of aluminum profiles. The main reason is that after the surface oxide film is damaged, aluminum reacts with oxygen, moisture, and other substances in the air to form black oxides (such as zinc hydroxide). Here are the specific processing methods:
Temporary handling plan for oxidation process after blacken:
Physical removal: Use sandpaper or steel wire balls to gently wipe the surface black spots, which can temporarily remove the oxide layer.
Chemical cleaning:
Soak specialized aluminum cleaning agent, react at room temperature and clean to remove oxides.
After boiling lemon water, wipe it and use acidic substances to decompose the oxide layer.
Long term protective measures for blacken oxidation process
Surface treatment:
1,Immediately perform anodizing treatment after grinding to form a dense protective film.
2,Apply rust proof oil or protective layer to isolate air contact.
Process optimization:
1,Reduce the proportion of recycled aluminum and minimize the amount of oxide film carried in.
2,Adjust the melting temperature and protective atmosphere to reduce the breakage of the oxide film.
Precautions:
1,Ordinary cleaning agents have limited effectiveness and are prone to recurrence. It is recommended to prioritize using professional cleaning agents.
2,High temperature or mechanical polishing may exacerbate oxidation, and caution should be exercised during operation
What is the difference between manual oxidation machine and semi automatic oxidation machine:
1, manual anodizing machine plant means the crane machine is simple hoist machine,remote control by hand
2, semi autoamtic anodizing machine plant means the crane machine is operate by manual, need labor press the button ,then the crane machine start work.
3,automatic oxidation machine means full controlled by PLC, only need labor to monitor the screen
