Abstract

The invention discloses a purple bronze aluminum alloy coloring system. The purple bronze aluminum alloy coloring system comprises a sulfuric acid tank used for anodizing an alloy profile, a coloring tank for electrolytically coloring the alloy profile, a hole sealing tank for sealing holes of the alloy profile, a rinsing tank for rinsing residual tank liquor of a hole sealing process, an electrophoresis tank for electrophoresis of the alloy profile and a curing unit for curing the alloy profile, and the sulfuric acid tank, the coloring tank, the hole sealing tank, the rinsing tank, the electrophoresis tank and the curing unit are sequentially connected. By means of the purple bronze aluminum alloy coloring system, the yield of purple bronze electrophoresis alloy profile products can be greatly increased.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to a copper-colored aluminum alloy coloring system. Background technique [0002] With the development of the economy, people pay more and more attention to the diversification and personalization of decorative colors. Because of the advantages of fine and soft tones and bright and transparent bottom after electrophoresis, copper salt colored electrophoretic alloy profiles are used in high-end buildings one after another. Alloy doors and windows replace the original stainless steel doors and copper doors. Copper colored electrophoretic alloy profiles have become a new type of material that is favored in the construction aluminum alloy profile industry, with huge market potential. [0003] However, copper-colored electrophoretic alloy profiles have a special production process, and chromatic aberrations are prone to occur during the production process, which in turn leads to...
