The current aluminum alloy profile appears in life as a common metal material. For example, computers and TV sets are supported by aluminum profiles, as are mobile phone casings, and desk partitions are also framed by aluminum profiles. And these aluminum alloy profiles have one thing in common, that is, the surface looks very smooth, but not too bright, but a low-key matte effect. So, how is the matt effect of the aluminum profile enclosure obtained?
In general, the matte effect of the aluminum profile enclosure surface is divided into physical and chemical processes.
1. The chemical process is generally divided into alkaline sand and acid sand.
The aluminum profile enclosure is generally carried out during the anodizing process of the aluminum profile. The alkaline sand process is to put the aluminum profile into a relatively high concentration alkaline solution to corrode the surface of the profile, thereby forming a matte effect. The principle of acid sand is similar. It all corrodes part of the surface of the aluminum profile. The surface effect of the aluminum profile treated by this chemical process will be more natural, but it will cause a certain amount of loss to the aluminum profile and is not environmentally friendly. In addition, the inner cavity of the aluminum profile treated by the chemical process will also have a matte effect, while the inner cavity of the sandblasted aluminum profile is still bright. Therefore, the matte treatment process of aluminum profiles should be selected according to product requirements.
2. The physical process is generally sandblasting, and emery is used.
The aluminum profile enclosure passes the aluminum alloy material through the sandblasting machine, so that the fine and dense sand makes even small pits on the surface of the aluminum profile, which are almost invisible to the naked eye. The aluminum profile presented in front of our eyes is still smooth. In terms of visual effect, the light becomes matte. The particle size of emery is not used, and the effect of spraying on the profile is also divided into thickness. After sandblasting, the aluminum profile is subjected to anodizing treatment to form a dense transparent oxide film on the surface to increase corrosion resistance.
