Anodic oxidation process for colour coated aluminium coil has many benefits:
1. Improve corrosion resistance: anodic oxidation will generate a layer of dense oxide film on the surface of aluminium coil, this layer of oxide film can effectively block the external environment of oxygen, moisture, corrosive substances, etc. and the aluminium coil substrate contact, which greatly improves the corrosion resistance of the colour coated aluminium coil, so that in the harsh use of the environment (such as moisture, acid rain, etc.) is not easy to be corroded, prolonging the service life.
2. Enhancement of wear resistance: after anodic oxidation treatment, the hardness of the surface of the colour coated aluminium coil increases significantly and becomes more wear-resistant. In daily use, processing and installation process, it is not easy to be scratched and worn, and can maintain good appearance and dimensional accuracy, suitable for occasions with high requirements on surface wear resistance, such as architectural curtain walls and interior decoration.
3. Enhance the adsorption and colouring ability: the oxide film formed by anodic oxidation has a porous structure, which makes the aluminium coil have a strong adsorption ability to various pigments and dyes. When colour coating is carried out, the paint can better adhere to the surface of the aluminium coil, and the colour is more uniform, bright, long-lasting and not easy to fade. It can achieve rich and diversified colour effects to meet the individual needs of different customers for colour and decorative effects.
4. Improvement of insulating properties: the oxide film after anodic oxidation is a good insulating material, which can improve the insulating properties of colour coated aluminium coils. In some of the electrical insulation requirements of the occasion, such as electronic equipment shells, electrical panels and other aspects of the application, can play a good role in insulation protection, reduce the risk of electric shock.
