[China Aluminum Industry Net] To effectively address water pollution caused by the production of aluminum alloy products, since 2012, Foshan Huachang Aluminum Profile Factory has been collaborating with South China University of Technology to develop a chromium-free passivation technology for aluminum alloys. After over six months of testing, several key performance indicators have met the expected standards.
According to an official from Huachang, their newly developed chromium-free passivation technology aims to replace the traditional chromate treatment method, which is known to cause significant environmental harm. This project has attracted attention from both the Guangdong Provincial and Foshan City Environmental Protection Departments. The company was selected as one of the "Key Energy-Saving and Emission Reduction Technologies" under the "2008 Guangdong-Hong Kong Key Breakthrough Projects in Key Areas (Foshan Special Projects)" initiative. They plan to complete the full development of this technology within three years. Although some wastewater test results are still not fully aligned with national standards, other properties such as impact resistance and bending strength already meet the required levels. The team is optimistic that the project will be completed ahead of schedule.
It's worth noting that the current surface treatment process in the aluminum extrusion industry typically involves chemical conversion coatings containing chromium compounds. These substances are toxic and can lead to serious environmental contamination and health risks if not properly managed. In contrast, the rare earth-based conversion film used in the new technology is non-toxic, environmentally friendly, and offers excellent corrosion resistance. As a result, this innovative approach has gained increasing recognition within the industry and is seen as a promising alternative to traditional chromate treatments. With growing demand for sustainable manufacturing practices, this technology is expected to play a key role in the future of aluminum surface treatment.
