The Basic Type of Industrial Aluminum Profile Aluminum Alloy-Huachang Aluminum-Aluminum Profiles SUPPLIER

Generally speaking, the basic example of industrial aluminum -type aluminum and aluminum alloy corrosion is: point corrosion, electrostatic corrosion, vulnerability corrosion, crystal corrosion, stress corrosion, peeling and corrosion, stress corrosion, silk corrosion, etc. The general signs of corrosion will occur during the production and use of industrial aluminum profiles. Point corrosion, also known as corrosion, is an extremely local corrosion form. It will produce fine dots on the metal, dots and holes. Damage of spots is a special case of anode response. It is a self -catalytic process. The aluminum, fresh water, and even the urban neutral solution will cause point corrosion, which will also cause perforation, but the external corrosion may eventually stop growing, and the amount of corrosion will remain at the limit value. Point corrosion is related to medium alloy of extreme levels, such as chloride ions, fluoride ions, etc. There must be substances that promote cathode response, such as dissolved oxygen, copper ions, etc. in the aqueous solution. From the perspective of industrial aluminum profile aluminum alloy, high -purity aluminum alloy profiles are usually difficult to generate point corrosion, and copper -containing aluminum alloy is the most important. Electric row corrosion is also a characteristic corrosion form of aluminum. The natural potential of aluminum is very great. When aluminum war with other metals, aluminum is always accelerated and corroded at the anode. Electric row corrosion is also known as dual metal corrosion. The severity of corrosion depends on the relative position of the two metal potential sequences. The greater the difference between their potential, the more serious the electric puppet corrosion is. The existence of the corrosion hole has loopholes in the appearance of industrial aluminum -type aluminum itself or aluminum materials. Due to the role of different inflatable batteries, the corrosion inside the vulnerability accelerates, but there is no effect on the outside of the vulnerability. Leakage and corrosion has nothing to do with the type of alloy, even if it is very resistant to corrosion alloys, it will produce leakage and corrosion. Over the years, the mechanism of dealing with loopholes has been more in -depth research. The acidic conditions on the top of the vulnerability are the driving force of corruption. Corrosion under sediment is a form of leaking corruption. Crystal corrosion, pure aluminum is not developed, crystal corrosion, and the cause of corrosion of the crystal inter -crystal is related to the improper thermal treatment process. The alloy elements or inter -metal inter -chemical compounds are precipitated along the crystal boundary. Causes the corrosion of crystal intervals to accelerate. Rotten rotten. Silk rot is a kind of subordinate rotten, growing under the film in the form of worms. This kind of paint film can be made into paint film and other layers, and it is usually not produced under the anode oxide film. Silk corrosion was first discovered under the aircraft layer. This year, it is reported in Europe that it also occurs under the construction of aluminum -shaped spray films of the construction industry. Filament corrosion and alloy characteristics, Jiangyin aluminum profile manufacturers' pre -processing punishment and condition factors. Condition factors are humidity, temperature, chloride, etc.
