Description

Technical Field

[0001] The utility model relates to the technical field of sandpaper, in particular to a super-flexible water-resistant sandpaper. Background Art

[0002] Sandpaper is an abrasive product primarily composed of abrasives and a binder, attached to paper, cloth, or other materials. It is primarily used to polish workpiece surfaces to remove burrs, rust, and other irregularities, or to achieve a desired finish and flatness. The abrasive particles on sandpaper are typically made of hard materials such as corundum, silicon carbide, and quartz sand. These particles are fixed to the base material with a binder, creating a grinding tool with a certain strength and wear resistance.

[0003] Sandpaper is a common abrasive tool, widely used for surface treatment of materials such as wood, metal, and plastic. However, traditional sandpaper has limitations in terms of flexibility and water resistance. In applications requiring complex surfaces or working in humid environments, traditional sandpaper is prone to breaking, resulting in a loss of grinding performance. Utility Model Content
