Introduction of brown corundum segmented sand:

Brown corundum segment sand is a kind of abrasive material, made from brown corundum as the main raw material. Brown corundum segment sand is actually the brown corundum block crushed and sieved into some grain size segment sand, are bauxite, anthracite, iron chips as raw materials using modern technology after high temperature treatment in electric furnace and made. After the subsequent processes can be screened out brown corundum segment sand, brown corundum fine powder, brown corundum micro powder and other different sizes and models of brown corundum series products.

Brown corundum segment sand has many breaks and sharp edges, which can form new angles in the continuous grinding and grading process, making its grinding ability better than other abrasives. It features short grinding time, high efficiency and low price. It is mainly used in shaped and unshaped refractories, coatings, furnace charge, steel sprues, sandblasting, waterjet cutting, grinding, surface treatment, surface rust removal, polishing and so on.

Brown corundum segment sand advantages:

1, recycling: this is a very important point in the characteristics of the very often, in general, the number of repetitions can be up to about ten times, after the use of brown corundum segmented sand waste can be added to the cement, can be recycled into the construction industry, reduce the user’s production costs.

2, less dust: sandblasting abrasives in the sandblasting stage will produce dust, the specific gravity is higher than other abrasives, in the use of the process of dust is also less, not only can improve the operating efficiency of the operator, but also by reducing the amount of dust inhaled by the operator to improve the operator’s health indicators.

3、High quality of surface treatment: When sandblasting, the abrasive can quickly enter the concave and convex part of the surface through the operation of the sandblasting machine to deal with the pollutants on the surface of the workpiece, and in addition to rust, it can also deal with the pollutants such as soluble salts, etc. The surface of the treated workpiece is very clean, and there is no insertion in the concave and convex part and the joints.

4、High efficiency: Generally speaking, the efficiency of brown corundum is related to its particle size, when the particles are small, the particles in the airflow will be faster and have sharp edges and angles, it will quickly hit the surface of the object to be operated, so as to achieve the purpose of sandblasting or grinding.

5, low loss: in the characteristics of low loss is to consume less product when dealing with a certain item, reduce the loss of abrasive, here the amount of impact of the particles on the surface of the object compared with the amount of garnet sand particles on the surface of the impact of the surface, relatively small, so its loss is low.

Brown corundum segmental grit areas of use:

Brown corundum segmented sand has a wide range of areas of use. It can be used for grinding, polishing and dressing processes in metalworking, ceramic processing, glass processing and other fields. In addition, brown corundum abrasive can also be used for surface treatment, such as spraying, sandblasting, etc., to improve the hardness and usability of the material surface.

 

The composition of white corundum is mainly industrial alumina powder, its main chemical composition is aluminium trioxide (Al2O3), with a content of more than 98%.

Support customisation, you can leave your demand on the left side form. We will contact you within 24 hours.

The hardness of white corundum is very high, the Mohs hardness is 9.0

Scratches appear in the polishing process because there are large grains in the abrasive product, resulting in a poor product appearance and poor cleanliness.
