The difference between brown corundum and other abrasives

Features of brown corundum: Due to the performance advantages of minerals, such as high hardness, good toughness, high specific gravity, and no harmful substances, brown corundum is a natural and environmentally friendly grinding material, which plays an important role in the international blasting and cleaning industry. character of. Used as blasting media accounts for 45% of all industrial usage. It can be seen that brown fused alumina is becoming more and more recognized in the blast cleaning industry.
Among various spray abrasives, the advantages of brown corundum mainly include the following points:
1. Less dust: Brown corundum is used for surface blasting treatment. Because of its relatively high specific gravity, less dust is generated during the blasting process. This ensures operator health and safety and improves operator visibility.
2. Under a certain pressure, brown corundum can quickly hit the surface of objects with sharp edges and corners in large quantities, so it is regarded as a very fast grinding method.
3. Low loss: The unique particle size of brown corundum ensures that more effective particles hit the surface of the object (such as 30-60 mesh sand, which can produce 11 million particles per kilogram to hit the surface of the object, while conventional slag, such as 20 mesh, can only Generate 1 million particles hit the surface of the object), so the use of garnet sand can greatly reduce the loss of abrasives - usually save 1/3 of conventional abrasives.
4. High-quality surface treatment: Brown corundum can penetrate deep into the caves and pits on the surface and reach the surface of the metal during the grinding process, so it can effectively remove all rust, water-soluble salts and other pollutants.
5. Environmental protection: Brown corundum, which is different from the conventional blasting material, is a kind of pure mineral. It does not contain free silicon harmful substances that cause silicosis, and does not contain toxic heavy metals or radioactive pollutants.
6. Recyclable: Brown fused alumina is very suitable for many fields. Normally, it can be reused 5-10 times. If it has not lost its cutting ability after 10 times, the number of cycles can be more. Brown fused alumina can also be recycled and used in the construction industry as a cement additive after it has no cutting ability.
To sum up, brown fused alumina is an ideal environmental-friendly blasting material, and it is worth trying to use by domestic enterprises. It is currently widely used in sandblasting, rust removal, optics, electronics, building materials, machining, meters, instruments, printing, grinding, stone, rubber, water jet and cutting industries. Especially in the last 10 years, the use of brown corundum as a pressure filter for water plants to replace quartz sand or gravel is a new application material in the field of non-abrasive applications.
