Anodized aluminum sheet cut to size can be seen everywhere in our lives, buildings, home improvement, electronic appliances and other fields are actually applied. And the anodized aluminum sheet is one of the outstanding representatives, and the anodized aluminum sheet is deeply loved by the masses because of some of its unique properties. The scope of application is also extremely broad.
What are the process steps in the treatment process of anodized aluminum sheet cut to size?
Mechanical polishing - degreasing - washing - chemical polishing - washing - anodizing - washing - closing - mechanical bright.
Chemical Polishing Products: Alkaline Polishing Liquid for Aluminum
Anodizing Products: Aluminum Anodizing Liquid
Finished Products: Aluminum Coil Coloring Anodizing and Dyeing Process.
Matters needing attention when anodized aluminum sheet cut to size anodizing:
1, After the aluminum coil is washed and oiled, it should be oxidized immediately and should not be left for too long. When aluminum parts are made of oxide film, they should be fully immersed in the electrolyte, and the tank voltage should be stable and consistent from beginning to end. The same batch of products must be completely consistent, which should be followed even when dyeing.
2, During the anodizing process, aluminum, copper, iron, etc. in the electrolyte are continuously added, which affects the luster of anodized aluminum sheet metal. When the aluminum content is greater than 24 g/L, the copper content is greater than 0.02 g/L, and the iron content is greater than 2.5 g/L, the electrolyte should be replaced.
3, When purchasing raw materials and dyes, you should choose products with high purity, because the general impurities are slightly more or when mixed with Yuanming powder and dextrin, the dyeing effect is not good.
4, In many dyeing cases, the dye solution is initially thick and then fades, and the dyed color will show different shades. Therefore, attention should be paid to mixing a slightly thicker dye solution in time to keep the consistency of the dye solution concentration as much as possible.
5, When dyeing multiple colors, the light color should be dyed first and then the dark color should be dyed in order of yellow, red, blue, brown and black. Before dyeing the second color, the spray paint should be dry, so that the paint is close to the anodized aluminum sheet cut to size surface, otherwise the dye will be immersed, and the hair boundary will be unclear.
