Abrasive media is a blasting material used to clean substrates during the removal process. Using compressed air, abrasive media is propelled towards and collides with a substrate material. When abrasive media like steel shots and aluminum oxide, come into contact with the substrate, they erode away unwanted materials. Blasting with abrasive media is an excellent method for cleaning surfaces that are heavily coated in contaminants, oil, and dirt, or simply have a slightly oxidized surface. Different types of abrasives will be required depending on the surface condition and the material type being blasted. In either case, abrasive media blasting is an excellent method for preparing a substrate.
Abrasive media for shot blasting machine is frequently used to prepare a surface prior to coating because if a coating is applied to a dirty or oxidized surface, the coating may fail prematurely or corrosion may form beneath the coating. Abrasive media blasting can help prevent this by removing contaminants and providing a smooth, clean surface for the coating to adhere to, preventing it from flaking, cracking, blistering, or otherwise falling off the surface of the material.
Abrasive garnet sand is blasted onto the surface of the steel with the use of high-pressure compressed air. This process helps in extending the life of the coating. It is used for oil firms, offshore applications, pipelines, and heavy machinery repair, and as an abrasive. The shot blasting machine uses abrasive Garnet with air pressure to clean or prepare surfaces for painting or other coatings. Sandblasting machines can also be used for the destruction of sand, it is also used to remove contaminated substances from metal products. Mesh sizes of abrasive garnet sand are Garnet 30/60 mesh, 10/30 mesh, 10/20 mesh, 20/40 mesh, 20/60 mesh, 40/60 mesh, and 80 mesh.
Aluminum Oxide is a sharp, long-lasting abrasive media that is highly efficient and highly reusable/recyclable thus cost-effective in nature. Harder than most blast media, Aluminum Oxide Blast Media, the powder will clean and etch quickly on all types of surfaces. The grits of this abrasive media are best for preparing the surface for the polishing and coating of blasting surfaces. It is also used often for surface cleaning because of the rugged nature of this blasting media.
Abrasive Steel Shots are spherical or round particles like a circular ball made of molten steel through an atomization process; these cast steel shots are available in different sizes & hardness. Steel shots are made from steel scrap. It is made in an electric furnace. First, the steel scrap is melted in the furnace then it is atomized/converted into the shot by a water jet.
Copper slag is a by-product of copper reduction by smelting. During dissolving, impurities become slag which floats on the molten metal. Slag that is quenched in water generates angular granules that are disposed of as waste or utilized as discussed below. This material represents a sought-after alternative to sand as a blasting medium in industrial cleanup. Using blasting or high-pressure spraying, companies, and factories can use the copper slag to clean large smelting furnaces or equipment.
Steel grit is fabricated by crushing, resulting in abrasive media and tempering it to the desired hardness. These abrasive Steel Grits are specially used in every type of wheel machine and also for blast rooms wherenozzles are employed in air blasting. Their sharp edges help in cleaning, etching, and smoothening the blasting surface easily.
