  • An assessment on the production of abrasive sandpaper

    Not always a highly versatile tool, coated abrasives were originally restricted to finishing applications such as polishing or preparing surfaces for painting or plating. through improvements in the strength of backings and the properties of abrasive minerals, coated abrasives now can be used for heavy-duty applications. today, industrial uses for coated abrasives range from hand polishing with sheets of coated abrasive to grinding steel with large machines that use 300-horse-power electric motors to drive belts several feet wide.

    Backings come in four basic materials, each with unique attributes. paper is the lightest of the backing materials and also the weakest. although its lack of material strength limits paperx0027s usefulness for hand applications, its flexibility makes it ideal for applications in which the coated abrasive must fit closely to the contour of a work piece. graded on a scale that increases with the physical weight of a ream, paper backings come in weights rated a to f. unless specially treated, paper cannot be used with water or other fluids.
