Surface treatment method of aluminum alloy profile

There are many aluminum alloy products, such as windows and doors, but after a long time of use, there will be scratches. So we have to perform surface treatment on aluminum alloy profile. The most common surface treatment methods for aluminum alloy profile include the following methods, which are worthy of reference.

? The aluminum profile of the frosted fabric

The frosted aluminum profile avoids the shortcomings of bright aluminum alloy profiles that will cause light interference in certain environments and conditions in architectural decoration. Its surface is as delicate and soft as brocade, which is very popular in the market. , But now some frosted materials must overcome the uneven surface sand, and can see the lack of pattern patterns.

? Multi-tone surface treatment aluminum profile

At present, the monotonous color can no longer satisfy the architects and the good matching of exterior wall decorative tiles and red brick latex.

The main function of sandblasting is surface cleaning. Sandblasting before painting can increase the surface roughness and make a certain contribution to the improvement of adhesion, but the contribution is limited and it is not as good as the pretreatment of chemical painting.

? Coloring

There are two main processes for coloring aluminum, one is aluminum oxidation coloring process, and the other is aluminum electrophoresis coloring process. Various colors are formed on the oxide film to meet the requirements of certain use. For example, the parts of optical instruments are often black, and the medals are golden yellow.

? Anodizing method

The anodizing method uses the electrolysis principle of direct current and alternating current to form an oxide film on the surface of the workpiece or product to increase the corrosion resistance and use a beautiful appearance method.

Electroplating treatment method: the workpiece is used as the cathode, the material forming the coating is used as the anode, and both of them are placed in the electroplating solution, and then direct current or alternating current and direct current is applied to ionize the material forming the coating And run from the electroplating solution to the surface of the workpiece, and firmly adhere to it to form a plating layer of different thicknesses.

The immersion treatment method is to first use a degreasing liquid to remove the oil stains on the net castings or products, and then rinse them with warm hot water at 25 to 35 degrees celsius for heat preservation.

The surface spray method is to spray paint on cast aluminum or aluminum alloy components and products in order to improve its corrosion resistance. For castings or products that require good corrosion resistance, aluminum castings or products should be anodized or chemically oxidized before painting. The purpose is to increase its own corrosion resistance, and the other is to use paint to bond the joints more firmly, and then Apply primer and topcoat. The shot peening method is to load the aluminum alloy castings into the drum of the shot blasting machine, and use high-speed running projectiles to spray on the surface of the castings. Since the casting is constantly turning at the same time, all the surfaces used are shot by the projectile and strengthened.

Vacuum spraying is to put the product or profile to be sprayed into the vacuum chamber of the spraying machine as the cathode, and the material forming the sprayed layer as the anode. After the vacuum chamber is closed, the vacuum is evacuated to a certain degree of vacuum. The sputtering material is sputtered and deposited on the product or profile as the cathode in an ion state to form a two-tenths of the sprayed layer, showing a variety of bright luster.
