What are the characteristics and functions of brown corundum abrasive?

Brown corundum is a commonly used abrasive for sand blasting. Do you know the characteristics of brown corundum abrasive used for sand blasting? Next, the manufacturer of b rown corundum abrasive will give you a detailed introduction!
1. High efficiency: generally speaking, the efficiency of brown corundum is related to its particle size. When the particles are small, the particles will move faster in the air flow, and have sharp edges and corners, which will quickly hit the surface of the operating object, so as to achieve the purpose of sand blasting or grinding.
Low loss: Brown corundum is characterized by low loss, which refers to a product that consumes less when processing an item. That is, to reduce abrasive loss, brown corundum particles have a relatively smaller impact on the surface of the object than garnet sand particles, so their loss is relatively low.
3. Less dust: sand blasting abrasives will produce dust in the sand blasting stage. The specific gravity of brown corundum is higher than that of other abrasives, and the dust generated during use is less. It can not only improve the working efficiency of operators, but also improve their health indicators by reducing the amount of dust inhaled by operators.
4. High quality of surface treatment: during sand blasting, brown corundum abrasive can quickly enter the concave and convex parts of the surface through the operation of the sand blasting machine, thus removing the pollutants, rust removal, soluble salts and other pollutants on the surface of the workpiece. The surface of the workpiece after brown corundum treatment is very clean, and there is no inlay at the concave and convex parts and joints.
5. Recycling: This is a very important feature of brown corundum. Generally speaking, the number of repetitions can reach about ten. Even if the recycling is ineffective, it can be recycled to the construction industry after adding cement, which means that environmental protection can reduce the production costs of users.
Brown corundum abrasive uses bauxite as raw material, and then adds a certain proportion of other raw materials. It is made at a high temperature of more than 2000 degrees in the electric arc. It is crushed and shaped by an autogenous mill, iron is removed by magnetic separation, and screened into various sizes. Brown corundum abrasive has dense texture, high hardness and spherical particles.
Brown corundum can be divided into segment sand, granular sand and micro-powder according to its particle size. Brown corundum grain size sand is produced by manually selected brown corundum blocks processed by roller, ball milling, Bamak, and other equipment. The particle size is f8-f325. Mainly used for polishing, grinding, industrial grinding, etc. It can also be processed by washing, picking and other methods according to customers' requirements to meet customers' different needs.
Role of brown corundum abrasive:
1. In order to reduce the carbon content of brown corundum, low-carbon brown corundum is reprocessed by special process in front of the furnace, so that it will not be crushed and broken during use, and has high toughness. It is a good raw material for abrasive tools industry and refractory industry.
2. Because brown corundum has high temperature resistance, corrosion resistance, high strength and other properties, the sliding nozzle is used to smelt rare special alloys, ceramics and blast furnace lining (wall, pipe); Physical and chemical utensils, spark plugs, heat-resistant and anti-oxidation coatings.
3. It can be used to manufacture corundum thermal insulation materials such as corundum lightweight bricks, corundum hollow balls, fiber products, etc., and is widely used in various high-temperature furnace walls and furnace tops with high temperature resistance and thermal insulation.
4. Brown corundum abrasive has the characteristics of high hardness, good wear resistance and high strength, and is used as a component of various reaction vessels and pipelines and chemical pumps in the chemical industry; Make mechanical parts and various moulds.
