Characteristics 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 environmentally friendly grinding material, which plays an important role in the international blasting cleaning industry. character of. Used as blasting media accounted for 45% of all industrial consumption. It can be seen that brown corundum is gaining more and more recognition in the blasting and polishing industry.

Among various jet abrasives, the advantages of brown corundum mainly include the following:

1. Less dust. Brown corundum is used for surface spraying treatment. Because of its high specific gravity, there is less dust generated during the spraying process. This ensures the health and safety of the operator and improves the visibility of the operator.

2. Brown corundum, under a certain pressure, can quickly hit the surface of an object with sharp edges and corners in a large amount, so it is regarded as a very fast blasting method.

3. The unique particle size of low-loss brown corundum ensures that more effective particles hit the surface of the object (such as 30-60 mesh sand, 11 million particles per kilogram can hit the surface of the object, while conventional slag such as 20 mesh can only produce 1 million particles hit the surface of the object), so that the use of garnet sand can greatly reduce the loss of abrasives-usually can save 1/3 of conventional abrasives.

Fourth, the surface treatment quality is high. Brown corundum can penetrate deep into the caves and pits on the surface and reach the surface of the metal during the blasting and grinding process. Therefore, it can remove all rust, water-soluble salts and other pollutants.

5. Environmental protection. Unlike the conventional blasting material, brown corundum is a kind of mineral, which does not contain free silicon harmful substances that cause silicosis, and does not contain toxic heavy metals or radioactive pollutants.

6. Recyclable brown corundum is very suitable for many fields. Under normal circumstances, 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. When there is no cutting ability, brown fused alumina can be recycled and used in the construction industry as a cement additive.

In summary, brown corundum is an ideal environmentally friendly blasting material, and it is worth trying to use by domestic enterprises. At present, it is widely used in sandblasting, rust removal, optics, electronics, building materials, machining, meters, instruments, printing, grinding, stone, rubber, hydraulic jet and cutting industries. Especially in the past 10 years, the use of brown corundum as a pressure filter in water plants instead of quartz sand or gravel is an emerging application material in the field of non-abrasive applications.
