There are many kinds of abrasives? why we should choose brown corundum(brown aluminum oxide ) as a sandblasting material ? The main reasons for choosing brown corundum sandblasting are as follows:
1. Excellent performance : Brown corundum has high hardness and toughness, which can effectively remove the dirt, rust and coating on the surface of the workpiece during the sandblasting process, while maintaining low sand consumption. Its sharp corners and edges enable brown corundum to produce a strong cutting force when it hits the surface of the object, thereby improving the sandblasting effect.
2. Environmental safety : Brown corundum is a non-polluting, non-toxic mineral, does not contain harmful substances such as free silicon that can cause silicosis, nor does it contain toxic heavy metals or radioactive pollutants. Therefore, the use of brown corundum sandblasting operations can ensure the health and safety of operators.
3. Recyclable : Brown corundum abrasive can be reused many times after sandblasting, reducing costs and reducing resource consumption. This is especially important in industrial areas that require a lot of sandblasting.
4. Strong adaptability : Brown corundum is suitable for various types of sandblasting machines and nozzles, which can meet different process requirements. At the same time, its unique particle size design ensures that the particles reach a large force area when they impact the surface of the object, thus reducing the loss of abrasive.
which grit Can be used for sandblasting of the brown aluminum oxide ?
The particle size of brown corundum that can be used for sandblasting mainly includes pure sand, such as 8#, 10#, 16#, 36#, 46#, 60#, 80#, 100# and so on. Different particle sizes of brown corundum are suitable for different sandblasting needs:
| 8# | Suitable for fine sandblasting, such as precision parts cleaning and deburring |
| 10# | is used for sandblasting operations with high surface quality requirements, such as auto parts |
| 16# | Suitable for general sandblasting treatment, such as rust removal and decontamination of metal surface |
| 36# | can be used for large area sandblasting treatment, such as the treatment of steel structure surface |
| 46# | is suitable for occasions where the sandblasting effect has certain requirements, such as shipbuilding |
| 60#, 80#, 100# | These larger grain size brown corundum is suitable for abrasive surface sandblasting treatment, such as Bridges, building steel structures,
Please note that the above particle size number and its use are only for general guidance, and the actual selection needs to be considered according to the specific material of the workpiece, the surface state and the required sandblasting effect. At the same time, in order to ensure the sandblasting effect and quality, it is also necessary to adjust the particle size and use mode of brown corundum according to the performance of the sandblasting machine, the size of the nozzle and the sandblasting pressure.
