As an ideal sandblasting medium, brown aluminum oixde is widely used in different sandblasting scenarios. Brown corundum with different particle sizes is suitable for different sandblasting requirements and workpiece surface conditions.
why choose brown corundum as a sandblasting material?
In the sandblasting process, brown aluminum oxide is selected as the main abrasive mainly because of its moderate hardness, strong wear resistance, good chemical stability and other characteristics. Brown corundum sandblasting can not only effectively clean the dirt and oxide layer on the surface of the workpiece, but also increase the surface roughness and improve the binding force between the coating and the substrate.
what are the common application scenarios of different grit ?
1. Coarse particle size (such as F8, F10) ** : suitable for heavy cleaning and rapid removal of surface oxide layer. These larger particle size brown corundum particles have a stronger impact force and can quickly remove dirt, rust and coating on the surface of the workpiece. They are often used in the pre-treatment phase to prepare for subsequent sandblasting or coating operations.
2. ** Medium particle size (such as F12, F16) ** : suitable for general cleaning and surface polishing. These moderately sized brown corundum particles can remove surface dirt without causing excessive damage to the workpiece. They are often used for the surface treatment of metal and non-metallic materials, such as rust removal and oxidation.
3. ** Fine particle size (such as F20 and above) ** : suitable for fine sandblasting and surface polishing. These smaller particle size brown corundum particles have less damage to the surface of the workpiece and can produce a more delicate surface effect. They are often used in demanding surface treatment applications, such as polishing and finish improvement of precision parts, molds, etc.
It should be noted that the selection of the appropriate particle size not only depends on the needs of sandblasting, but also closely related to the workpiece material, coating requirements and other factors. Therefore, in practical applications, it is necessary to make comprehensive consideration and selection according to the specific situation. At the same time, in order to ensure the sandblasting effect and workpiece quality, it is also necessary to strictly control the sandblasting parameters and operation process, and strengthen safety management and staff training.
