abráziív

Abráziív is a term used to describe a substance or process that causes abrasion. Abrasion itself refers to the mechanical wearing away or scraping of a surface through friction. Abráziív substances are typically hard and granular, allowing them to effectively remove material from a substrate. Examples of abráziív materials include sand, grit, and various mineral compounds. The effectiveness of an abráziív depends on factors such as particle size, hardness, and shape.

The process of abrasion, and therefore the use of abráziív materials, is employed in a wide range of applications. In industry, sandblasting, a common abrasive process, uses high-pressure air or water to propel abráziív particles at a surface. This is used for cleaning, surface preparation, and shaping. Grinding and polishing also rely on abráziív action to smooth and refine surfaces. In everyday life, abrasive pads are used for cleaning dishes and surfaces, and sandpaper, made with abráziív particles adhered to a backing, is used for woodworking and finishing. The controlled removal of material through abrasion is a fundamental technique in many manufacturing and maintenance activities.
