The Principle of Sandpaper and Abrasive Cloth

The main principle of sandpaper and abrasive cloth is to sand a surface through the friction of abrasive grains. The back of sandpaper and abrasive cloth is covered with adhesive, which holds the abrasive grains in place. Carpenters can attach the sandpaper or abrasive cloth to the workpiece by hand and achieve the sanding effect by manually rubbing the surface.
