In the production process of aluminum profile frame, in addition to the need to weld its various interface parts, but also need to do a good job of anti-corrosion treatment of the whole material, so as to make the whole frame can be used to effectively prolong the time, delay the subsequent material corrosion, rust bad speed. Then the process of anti-corrosion treatment on the surface of aluminum profiles, what are the specific?
The coating process
This type of process is to select a material with the help of a special process, so that the material on the surface of the aluminum form a protective layer, also known as surface coating or coating. The application of this kind of process can not only protect the aluminum frame well, but also play a role in decorating the aluminum frame.
Chemical conversion anticorrosion treatment
The aluminum profile is placed in the chemical conversion treatment solution, so that it reacts with the substance inside the solution. Compared with the general voltage chemical film conversion process, the application of this method is more direct and simple, and effectively improves the efficiency of the whole anticorrosion treatment process.
Electroplating anticorrosive treatment technology
The surface of aluminum profile frame is electroplated, that is, a layer of metal materials with higher corrosion resistance and hardness is electroplated on its surface to improve the performance of aluminum profile itself. In the actual application, to do electroplating processing aluminum profiles, is used for decoration purposes. It should be noted that when the surface of aluminum profile is anticorrosive with the help of electroplating process, an oxide film will be formed when the aluminum profile is exposed to the air for a short period of time, so it is easy to affect the effect of electroplating. Therefore, it is very important to clean and treat the material before electroplating when the surface of aluminum profile is treated by electroplating process.
The quality of aluminum frame is not only related to the type of aluminum profile selected, but also the connection of each frame part in the whole production process is firm and the overall frame anticorrosion work is in place, which will affect the use of the frame. It can be seen that in the process of aluminum profile frame processing, all the working procedure problems in the processing process should be done in order to better guarantee the quality of the produced frame.
