Chrome-free passivation treatment technology for aluminum alloy products
According to the relevant person in charge of Huachang, the chromium-free passivation treatment technology developed by them is to replace the commonly used chromate treatment technology, which can effectively solve the problem of water pollution in the production of aluminum alloy products. This project received the attention of the environmental protection departments of Guangdong Province and Foshan City. In the “2008 Guangdong and Hong Kong key breakthrough projects in key areas (Foshan Special Projects)†tender, the company won the “key energy-saving and emission reduction technology†target and plans to complete the entire set of technologies within three years. Research and development. After more than six months of experimentation, a number of indicators have achieved the desired results. "In addition to the waste water test, its performance is still a certain distance from the national standards. Other indexes such as impact resistance and bending resistance have already met the requirements of national standards. It is expected that this project can be completed in advance."
It is understood that the surface treatment currently used in the aluminum extrusion industry is usually treated with a chemical conversion process. The chromium compounds contained in this process formulation are toxic chemicals that are emitted when improperly handled and will not only cause environmental pollution, but also It will endanger human health. The rare earth conversion film has the characteristics of non-toxicity, no pollution, and good anti-corrosion effect. This new technology has been highly valued by the industry in recent years and is expected to become one of the main chromate conversion substitution technologies.
