As an Aluminum Rack System Factory, let me share with you. Aluminum pipes
sometimes turn black when left in the warehouse. In terms of degreasing
treatment before oxidation of aluminum tubes, most factories still use weak
alkali chemical degreasing or caustic soda degreasing and whitening to improve
operating conditions. The effect of surface treatment before oxidation of
aluminum tubes on the quality of aluminum products' material composition and
purity has long been known to scientific and technological workers. The aluminum
tube sometimes turns black if it is kept in the warehouse for time, which means
that the aluminum tube has started to oxidize. After the aluminum tube is
oxidized, the oxide can be wiped off and placed in the sun for a few days to
solve the oxidation problem. Aluminum tubes can produce and process aluminum
hard anodized with a length of 3m, and can be used for oxidation processing of
mechanical parts, textiles, electronics, auto parts, communications, cooking
utensils, speaker audio, printing peripheral parts, LEDs, solar panel bracket
aluminum tubes, etc.
Aluminum Pipe
The wall thickness of industrial aluminum profiles will not be too thin. Unlike architectural aluminum profiles, industrial aluminum profiles only play a decorative role, and the wall thickness will be very thin. Industrial aluminum profiles generally play a supporting role and require a certain load-bearing capacity, so the wall thickness should not be too thin.
There are two types of industrial aluminum profiles: the national standard and the European standard. The difference between the European standard aluminum profile and the national standard aluminum profile is also in the notch. The European standard is a trapezoidal slot with a large upper and a smaller one. The national standard slot is a rectangular slot, and the upper and lower are the same. The connectors used in the national standard and the European standard are different. I personally think that the European standard industrial aluminum profile is better. The European standard has more specifications than the national standard. There are also some customized non-standard industrial aluminum profiles, which can be used with European standard connectors or national standard connectors.
Anodizing of industrial aluminum profiles is a process of electrolytic oxidation in which an oxide film is formed on the anodes of aluminum profiles. The purpose is to increase the hardness of aluminum profiles, expand the use range of aluminum profiles, and increase the service life of aluminum profiles. In the process of anodizing, you can choose the color you want to make, such as black, silver, red, purple and so on. These needs are made according to the needs of users. It can be seen from this point that the anodizing of industrial aluminum profiles is actually decorative.
The original color oxidation of industrial aluminum profile is actually the same color as the previous one, no difference. Just like what color the aluminum ingot is, what color is the oxide film formed. Unlike anodizing, there are so many color choices. Compared with the advantages of anodic oxidation, such as protection, decoration, insulation, etc., natural oxidation may appear to be slightly insufficient.
