Layer Structure of Color Coated Aluminum Sheet
- Aluminum Sheet Substrate: It is the core base material with various aluminum alloy options. Good ductility and corrosion resistance fit diverse usage environments.
- Front-side Chemical Conversion Layer: Surface passivation improves adhesion between substrate and coatings to prevent paint blistering and peeling.
- Primer: This bonding layer connects the top coat and conversion layer, avoiding coating cracking or peeling during bending processing.
- Top Coat: The outer decorative and weather-resistant layer protects the substrate from UV rays, acid rain and abrasion.
- Back-side Chemical Conversion Layer: Passivation treatment on the back ensures stable adhesion of the back protective coating.
- Back Coated Layer: It protects the substrate against oxidation, moisture corrosion and scratches during stacking, transport and storage.
Color Coated Aluminum Sheet Production Process
- Raw Material Inspection: Check the specification, thickness and surface quality of aluminum coils.
- Surface Pretreatment: Degrease, clean and conduct chemical passivation to improve coating adhesion.
- Primer Coating & Curing: Apply primer evenly by roller coating, then bake to dry.
- Top Coating & High-temperature Baking: Roll coat the top finish paint and cure at a set high temperature.
- Cooling Treatment: Cool the coated aluminum coil to room temperature.
- Surface Quality Inspection: Check for color deviation, scratches, bubbles and coating defects.
- Finishing Processing: Rewind into coils or level and shear into aluminum sheets.
- Final Inspection & Packaging: Carry out overall inspection, pack finished products and store in warehouse.
