Description

Technical Field

[0001] The utility model relates to the technical field of sandpaper production equipment, in particular to a spraying tool for producing aluminum oxide sandpaper. Background Art

[0002] Alumina sandpaper is a type of sandpaper with aluminum oxide particles as abrasives, which is usually used for surface grinding and polishing of materials such as metal, wood, and plastic. Alumina particles have the characteristics of high hardness, wear resistance, and good chemical stability, so they are widely used in sandpaper manufacturing. The basic steps for making aluminum oxide sandpaper are as follows: 1) Prepare the substrate: Select a suitable substrate, such as paper, cloth, etc., and cut and process it as needed; 2) Glue coating: Apply an appropriate amount of glue on the substrate to adhere the aluminum oxide particles to the substrate. 3) Sanding: Sprinkle the aluminum oxide particles evenly on the substrate coated with glue to ensure that the particles are evenly distributed. 4) Hot pressing: The sanded substrate is hot pressed to make it tightly bonded to the substrate. 5) Drying: Dry the hot pressed sandpaper to remove excess moisture and glue. 6) Cutting: Cut the dried sandpaper into appropriate sizes and shapes as needed. It should be noted that the process of making aluminum oxide sandpaper requires precise control of various parameters, such as the particle size of aluminum oxide particles, the thickness of the glue coating, the temperature of hot pressing, etc., to ensure the quality and performance of the sandpaper.

[0003] Alumina sandpaper production requires the use of spraying tools for gluing operations, but the traditional spraying tools for aluminum oxide sandpaper production have been found to have shortcomings when used.
