Now aluminum plate is very common in our daily life, and there are many types of aluminum plate, aluminum plate in the production process will appear some black spots, then will lead to the surface of the aluminum plate how to appear black spots?

1. There are different kinds of aluminum plates now, but the materials of these aluminum plates, when processing, if the parts do not appear black spots, this is not the fault caused by the defect of the raw material, which leads to the fault of the black spots in the processing of aluminum plates is the influence of sulfur element on the silver plating layer.

2. In the spray painting process of aluminum plate, it was found that the whole batch of records of repair appeared in the spray painting process, the reason is that the gap is not blocked, and the surface can not be removed, in order to prevent the occurrence of such failures, the gap is sealed, the parts are not packaged and sealed in time, and the silver plating layer is yellow for a long time in the electroplating factory room.

3. After silver plating, the faulty parts are promptly packaged and stored in dry utensils, which is not affected by the air atmosphere of the workshop. In the case of production conditions, similar parts processed at the same time do not fail, so the factors that change the production conditions of electroplating are excluded.

Aluminum plate common problems and solutions

Aluminum plate is widely used in all walks of life, it is a very popular building decoration material, in the use of aluminum plate, will certainly encounter some problems, the following is to talk about the common problems and solutions of aluminum plate.

1, aluminum-plastic board discoloration, decolorization: choose the correct aluminum-plastic board, various types of aluminum-plastic board have their own service life, qualified aluminum-plastic board in its service life is not discoloration, fade. If there is discoloration, fading, it may be due to improper selection of plates. Choose the right cleaning agent, the use of corrosive cleaning agent when cleaning aluminum plastic board will also cause the color of aluminum plastic board discoloration, fade.

2, the opening and falling off of aluminum-plastic board: choose the right adhesive, the opening and falling off of aluminum-plastic board is mainly due to the improper selection of adhesives. When buying aluminum-plastic panels, the seller will recommend that special quick-drying glue. This kind of glue can be used indoors, and when used outdoors in the changeable climate, the phenomenon of plate opening and degumming will appear

3, the deformation of the surface of the aluminum-plastic plate, drum: the use of aluminum profiles as the skeleton, this kind of metal material made of the skeleton, its cost is not much higher than the wooden keel, high-density plate, can indeed ensure the quality of the project.

Why does the extrusion surface of aluminum sheet skin blister? Maintenance method?

When it comes to aluminum plate, we should have seen it more or less everywhere, and it is widely used, such as: furniture and appliances, building materials, elevator walls, aerospace military, mechanical parts and so on. Use a long time have some loss, the following Zhengzhou aluminum plate staff for you to talk about the aluminum plate extrusion surface foaming causes and maintenance methods?

Why is aluminum sheet foaming?

1. Under normal circumstances, if the size of the extrusion cylinder and the extrusion pad do not match, the use of the wrong method, and the use of the process is not cleaned up in time, it will cause the wear of the aluminum plate.

2. The temperature cannot be too high, the so-called thermal expansion and cold contraction, once the extrusion cylinder temperature is too high, exceeds the specified value, and the temperature is unstable, the aluminum sheet will be deformed and expanded, thus peeling and foaming.

3. It may also be that the design is unreasonable and there is gas entering it.

Should first clean the surface of the aluminum plate with clean water, and then wipe the surface with a soft cloth with neutral detergent, and then rinse the surface of the aluminum plate with clean water until all washed.
