Why Does the Industrial Aluminum Profile Appear Rust? -WJW Aluminum Supplier Aluminum

Compared with the remaining construction materials, the industrial aluminum profiles are relatively rare to show oxidation and rust, but this situation cannot be completely eliminated. The field of industrial aluminum photo application is divided. Industrial aluminum profile refers to all aluminum profiles other than aluminum profiles of building doors and windows, curtain walls, indoor and outdoor decoration and building structure. In the process of using industrial aluminum profiles, which factors will cause it to be corrupted and show rust spots? The following analysis will be made for everyone:

Point corruption, point corruption is also called corruption. It is a very local corruption condition produced on the metal. Point corruption is a strange situation of anode reaction and a self -catalytic process. Aluminum is in the atmosphere, fresh water, and neutral water solution, which will produce point corruption, and the major ones may also cause perforation. However, the corruption hole may still end the development, and the amount of corruption adheres to a limit value. Point corruption is related to medium alloy, such as chloride ions, fluoride ions, etc. There must also be substances that improve cathode reactions, such as dissolved oxygen and copper ions in the aqueous solution. From the perspective of industrial aluminum profile aluminum alloy, it is difficult for aluminum profile high -pure aluminum to produce point corruption individuals, and copper -containing aluminum alloy dots are relatively obvious.

Electric rotting is also the characteristic of aluminum characteristics. The natural potential of aluminum is very negative. When aluminum is in contact with the remaining metals, aluminum is always in anode to accelerate it. The field of industrial aluminum photo application is divided. Industrial aluminum profile refers to all aluminum profiles other than aluminum profiles of building doors and windows, curtain walls, indoor and outdoor decoration and building structure. Electric rot is also known as dual metal corruption. The major level of corruption is determined by the absolute position in the two metal potential sequences. The greater the difference between their potential, the more important the electric puppets are, and the somewhat aluminum alloys cannot avoid the corruption of the electric puppet.

The gap is rotten, and the industrial aluminum aluminum itself or the aluminum is in the name of the other information. There is a gap in the name of the other information. Because of the effect of differential inflatable batteries, the gap is accelerated, and the gap does not affect. The gap rot is not related to the type of alloy. In recent years, the mechanism of corruption of gaps has been deeper. The acidic environment at the top of the gap is the original energy of corruption. Corruption under sediment is a situation of gaps.

Crystal corruption, pure aluminum non -prosperous crystal corruption, and the cause of corruption between crystal intervals are related to inaccurate heat treatment. The alloyed elements or inter -metal intervertebral compounds are accumulated along the crystal boundary. Essence

Silk -shaped corruption, silk corruption is a kind of sub -film rot, developed in the shape of a insect -like development. This membrane may cause the paint film or make the rest of the layer. Individuals are not produced under the anode oxide film. The field of industrial aluminum photo application is divided. Industrial aluminum profile refers to all aluminum profiles other than aluminum profiles of building doors and windows, curtain walls, indoor and outdoor decoration and building structure. Silk -shaped corruption was invented under the layer of the aircraft, and this year, it has been reported to be under the construction of an aluminum -type spraying film in the construction of the industry. Silk -shaped corruption and alloy composition, pre -processing before the coating of aluminum -shaped coating has humidity, temperature, chloride, etc. related to environmental factors.

The above is an important factor that leads to rust spots in the industry's aluminum profiles. I look forward to benefiting you!
