The use of brown corundum abrasives can be recycled, and whether brown corundum abrasives can be reused and the number of times they are used, mainly by the material being sandblasted, the hardness and grade of brown corundum, and the size of particles and other factors, such as 24 mesh, 36 mesh, 46 purpose primary brown corundum can be reused more than 6-8 times, secondary brown corundum can be reused more than 4-6 times, tertiary brown corundum can be reused more than 3-4 times.
Different grades of brown corundum are reused differently, and the material of the sandblasted workpiece is different, which will also affect its utilization rate. Nowadays, environmental protection problems are becoming increasingly serious, and the utilization rate of non-toxic and harmless brown corundum abrasives has been greatly improved. It can avoid large-scale dust, and also save greater costs for enterprises.
Advantages of sandblasted brown corundum:
1. Because brown corundum has a higher specific gravity, less dust is generated during the spraying process. This ensures operator health and safety and improves operator visibility.
2. Brown corundum can quickly impact the surface of the object with sharp edges and angles under a certain pressure, so it is considered a very fast spraying method.
3. The unique particle size of brown corundum ensures more effective particles hitting the surface of the object, so the use of brown corundum can greatly reduce the loss of abrasives, usually saving 1/3 of conventional abrasives.
4. The surface treatment quality is high, and brown corundum can penetrate the caves and pits on the surface during the spraying process to reach the exposed surface of the metal, thereby removing pollutants such as rust and water-soluble salts.
5. No pollution, unlike traditional abrasive materials, brown brown corundum is a non-polluting and non-toxic mineral, which does not contain harmful substances such as free silicon that can cause silicosis, nor does it contain toxic heavy metals or radioactive pollutants.
6. Recyclable, brown corundum is suitable for many fields. Under normal conditions, it can be reused 5 to 10 times. If the cutting ability is not lost afterwards, the number of cycles will be higher.
