Introduction
Interpretation of the Technical Specifications for Anodic Oxidation and Anodic Oxidation Electrophoretic Coating of Aluminum Alloy Building Profiles
Background of Standard Formulation
With the growing demand for aluminum alloy materials in my country's construction industry, anodizing and electrophoretic coating are key processes for improving the corrosion resistance and decorative properties of aluminum alloys, and their technical specifications are particularly important. GB/T 23612-2017 replaces the old standard GB/T 23612-2009, mainly optimizing and supplementing the process flow, equipment requirements and environmental protection measures.
Technical Evolution Analysis
- Added requirements for recycling of washing tanks to improve water resource utilization.
- Optimized the protection system of anodizing power supply to ensure safe operation of equipment.
- Introduced nickel-free and fluorine-free cold sealing process to reduce the emission of harmful substances.
| Process | Key parameters | Temperature range | Bath composition |
|---|---|---|---|
| Degreasing | Processing time: determined according to surface requirements | Room temperature | As required by the degreasing agent supplier |
| Anodizing | Voltage: 10 V~20 V Current density: 100 A/m²~200 A/m² | 20℃±2℃ | 130 g/L~200 g/L sulfuric acid |
| Electrolytic coloring | Bath composition: 150 g/L±5g/L nickel sulfate, 40 g/L±5 g/L boric acid | 25 ℃±3℃ | pH value 3.8~4.2 |
Implementation suggestions
- Enterprises should conduct regular inspection and maintenance of production equipment according to standard requirements.
- During the anodizing and electrophoretic painting process, strictly control the composition and temperature of the bath to ensure product quality.
- It is recommended to use a nickel-free and fluorine-free sealing process to meet environmental protection requirements and improve product performance.
