Abrasives are worldwide popular for its grinding or sanding operations and polishing application across wide range of industries

 

An Abrasives is any material, usually a naturally occurring mineral, which is used to carefully shape or polish a workpiece so as to result in some portion of the workpiece becoming worn away by abrasion. The abrasion is usually a radial motion, which means that a piece of material is worked on at a high speed. Commonly, they are used in abrasive grinding or sanding operations. They are often made of steel or aluminum alloys, with other materials also sometimes used. In addition to being used in abrasive grinding and sanding, abrasives are sometimes used for polishing as well.

While an Abrasives can be made out of many different materials - including steel wool, an egg carton, and baking soda, to name a few - most of them are generally made out of either silicon carbide or sodium bicarbonate. These materials are mixed together and then formed into either a powder or a paste, depending on what exactly is needed to produce the final product. Typically, an abrasive is mixed with an oxidizer that helps to increase the speed with which the material is able to get things to move along their way, and also the thickness of the material that will be used. The oxidizer, in many cases, will be some kind of acid; for example, urea acid, hydrochloric acid, or sulfuric acid.

The types of materials used in Abrasives fall into two broad categories. One consists of synthetic, which are usually prepared from metallic salts of various compositions. The other consists of natural minerals such as marble, limestone, granite, soapstone, quartz, and many others.

When an abrasive is used in Abrasives grinding or sanding operations, it typically results in a soft, wear-resistant surface. Some types of naturally occurring abrasives, including calcium, magnesium, and silicon carbide. Other commonly used materials in abrasives include manganese oxide, boron carbide, zinc oxide, and magnesium carbonate.
