Quick determination technique of aluminum oxide film defect at aluminum anode
1, the appearance of aluminum oxide film frost: this kind of appearance is generally caused by the oxidation liquid temperature is too high, in more than 25 degrees, it is very easy to appear powder frost, so the most suitable temperature is 10-20 degrees. In addition, the current is too high will also cause powderization.
What defects are prone to aluminum profile surface treatment?
There are three common surface treatment methods for aluminum profiles: anodizing, electrophoretic coating and powder spraying, of which anodizing is mainly used for the surface treatment of industrial profiles, and electrophoretic coating and powder spraying are mainly used for the surface treatment of building profiles and decorative profiles. These three surface treatment methods have their own advantages, but the main role is to prevent the surface corrosion of the profile and increase the beauty. So are there any disadvantages to these surface treatments? In fact, no matter what kind of treatment will have its defects, how to prevent these defects is a problem we need to discuss.
Solutions to the oxidation of industrial aluminum profiles
Industrial aluminum profiles are commonly used materials in many industries. But in the process, it's not so easy. Usually, due to various factors, the shape of aluminum alloy is not perfect. Among them, aluminum alloy profiles are easy to oxidize, which is a headache.
Aluminum anodizing Using aluminum anode anticorrosion precautions?
In today's production and living fields, a large number of steel products cause huge economic losses every year because of corrosion, and in the increasingly in-depth situation of industrial production, this harm is also further increasing.
The anodic oxidation dyeing process of aluminum parts is introduced
Dyeing monochrome method: at 4 o 'clock, the aluminum products that have been anodized and washed with water are immediately immersed in the coloring solution. 40-60℃. Soaking time: light 30 seconds to 3 minutes; Dark, black for 3-10 minutes. After dyeing, remove and wash with water.
There are these changes in the mass size of aluminum alloy before and after oxidation!?
Many people have a question: "Why do pores get bigger after oxidation?" This should be explained from the principle of oxidation, oxidation is different from spraying or electroplating, anodizing is carried out on the surface of aluminum alloy, it is a process of reaction from the surface to generate an oxide film.
What are the polishing methods commonly used for aluminum alloy die casting?
The Double Ninth Festival, also known as the Double Ninth Festival, is a traditional Chinese festival that falls on the ninth day of the ninth lunar month. This festival falls in October or November of the Gregorian calendar. It is a festival for respecting the elderly, admiring autumn, and carrying out various cultural activities. In recent years, as businesses have become more aware of the importance of social responsibility, the significance of the Double Ninth Festival has expanded beyond personal and family celebrations. One trend worth noting is the distribution of benefits to villagers during festivals.
The three most taboo colors for polishing alloy surfaces
The most taboo colors on the surface of the polished alloy are blue, yellow and green. These colors often indicate possible problems or defects in the polishing process.
