Chemical conversion film treatment is in the surface treatment for aluminum and aluminum alloy corrosion resistance of the most widely used technology, the development of more than half a century of chemical conversion coating technology becoming mature, and constantly to derive other new processing methods.There is no doubt that chemical oxidation will play an important role in the future.However, due to the increasingly serious environmental pollution, the cleaning and pollution of the surface treatment process have higher requirements.This can be perfected in the following directions.
1. Low-temperature development of metal surface pretreatment to develop energy-saving surface treatment technology.
2. Low chromium and chrome-free treatment.
3. No washing process: eliminate the washing process of the whole process. Besides, the water resources can be saved in addition to the environmental pollution problem.Japan reported: chromate surface treatment agent, is Cr3, +, Cr6, + and a mixture of water soluble organic resin, used in aluminum plate, the coating film forming method is adopted, not washed, even including chromium ion will not pollute the environment;Natural drying, convenient for sealing system processing;Membrane corrosion resistance and coating adhesion are the same as the surface treatment of the past, even better.
4. The pretreatment process and the film processing technology adopt the mutual closure cycle, and all the chemical agents in the system are recycled, and the original liquid is not replaced, and the consumed drugs are added regularly.Water wash treatment or non-water treatment can be closed.The closed process can greatly improve the on-site operation environment, reduce waste residue and waste liquid discharge, save energy and resources, and the economic and social environmental benefits are obvious.
