Types of Abrasive Materials
Abrasives can be used in a variety of ways by many different kinds of companies. Especially when you have products that need to be progressed to a completed state by buffing, sanding, grinding, or polishing. As long as the abrasive is harder than the material you're trying to finish, it will be an effective way to hone it and prepare it for use.
Types of abrasive materials
Abrasives consist of minerals that can be either naturally occurring or synthetic, such as calcite, emery, pumice, sandstone, garnet, borazon, ceramic, steel abrasive, and silicon carbide. When used for industrial applications such as mining, construction, railroad, and wholesale/retail operations, usage falls into several different categories, depending on the type and shape of material to be finished:
Bonded – These types of abrasives are generally contained within some kind of matrix, such as clay, resin, or rubber, and then shaped into wheels or blocks. The sides often have two different grit densities. A grinding wheel is a good example of a bonded abrasive, operating at very high speed to finish any material pressed against it. Bonded abrasives most commonly consist of aluminum oxide, silicon carbide, tungsten carbide, or garnet.
Coated – Sandpaper is the most common type of coated abrasive. Coated abrasives, such as sandpaper, are made by affixing an abrasive to a backing material, such as paper or metal. Resin or another adhesive bonds the abrasive mineral to the paper, creating the gritty sandpaper surface. Sandpaper comes in many shapes and sizes and can be used with various sanding tools. Miscellaneous abrasive applications, such as sandblasting, which use materials like metal pellets, sand, or glass beads. Cleaning products that everyone is familiar with often contain a mild abrasive and are used to clean floors, pots, pans, and other surfaces.
