Abrasive Sand Multifunctional Surface Treatment Material

A more accurate definition differentiates China's abrasives into rough and precision graded. For the purpose of this writing, rough abrasive sand will be used, which means abrasive particles with a particular mesh size restriction, that have not been sorted by other dimensions are called precision graded abrasive sand. In the semiconductor industry, precision graded abrasive sand is used for polishing silicon wafers and due to the strict requirements to have a smoother and more uniform surface for higher optical components it is reasoned by the smooth and even polishing they require. Precision grading guarantees that every grain has the same impact of abrasion which yields lesser changeability when it comes to most abrasive executions.
