Abrasive non-woven discs are made from a web of synthetic or natural fibers. These fibers are bonded together with adhesives and impregnated with abrasive particles. The result is a flexible and durable material that can be used for various grinding and polishing applications.
-
Fibers: Commonly used fibers include polyester and nylon. Polyester fibers offer good strength and durability, while nylon fibers provide excellent flexibility and resistance to abrasion.
-
Abrasive Particles: Abrasive grains such as aluminum oxide and silicon carbide are the most frequently used. Aluminum oxide is known for its high hardness and durability, making it suitable for grinding and polishing hard materials. Silicon carbide is extremely sharp and can cut through materials quickly, making it ideal for applications where fast material removal is required.
-
Adhesives: Adhesives play a crucial role in holding the fibers and abrasive particles together. They ensure that the abrasive non-woven disc maintains its shape and integrity during use. Common adhesives include epoxy resins and phenolic resins, which offer strong bonding strength and resistance to heat and chemicals.
-
Good Flexibility: Abrasive non-woven discs are highly flexible, allowing them to conform to the shape of the workpiece. This makes them suitable for grinding and polishing curved or irregular surfaces.
-
Efficient Grinding Performance: With the abrasive particles evenly distributed throughout the material, abrasive non-woven discs can provide efficient and consistent grinding and polishing results. They can remove material quickly and leave a smooth finish on the surface.
-
Long Service Life: The combination of high-quality fibers, abrasive particles, and adhesives gives abrasive non-woven discs a long service life. They can withstand high temperatures and pressures without losing their abrasive properties.
-
Applicable in Both Wet and Dry Environments: Many abrasive non-woven discs are designed to be used in both wet and dry conditions. This provides users with more flexibility in their grinding and polishing operations.
-
Metal Processing: In the metalworking industry, abrasive non-woven discs are widely used for grinding and polishing metal surfaces. They can be used to remove rust, scale, and burrs from metal parts, as well as to achieve a smooth and shiny finish.
-
Wood Processing: For woodworking applications, abrasive non-woven discs are used for sanding and smoothing wood surfaces. They can remove rough spots and imperfections, preparing the wood for painting or finishing.
-
Automotive Maintenance: In the automotive industry, abrasive non-woven discs are used for paint removal, surface preparation, and polishing. They can be used to repair scratches and dents on car bodies, as well as to restore the shine of the paintwork.
-
Stone Processing: Abrasive non-woven discs are also used in the stone processing industry for grinding and polishing stone surfaces. They can be used to create a smooth and polished finish on marble, granite, and other types of stone.
-
Usage Methods: First, select the appropriate abrasive non-woven disc according to the material and processing requirements. Then, install the disc on the corresponding grinding or polishing equipment. When using, keep the disc perpendicular to the workpiece surface and apply appropriate pressure. Move the disc evenly across the surface to achieve the desired grinding or polishing effect.
-
Precautions: Wear appropriate personal protective equipment, such as safety glasses and gloves, when using abrasive non-woven discs. Avoid using the disc at excessive speeds, as this may cause the disc to break or wear out quickly. Store the discs in a dry and cool place to prevent moisture and heat from affecting their performance.
