The types of abrasives, bases, binders, and processes used in sandpaper are constantly improving. For some water sandpaper, dry sandpaper, sponge sandpaper and other grinding processes, they have the advantages of high production efficiency, good surface quality of processed devices, and low production costs. Therefore, they are widely used in furniture production. The final product quality of home products is inseparable from the grinding process. Sponge sandpaper is the main tool for polishing technology.

Sponge sandpaper is a strip-shaped tool used for grinding and polishing by bonding abrasive materials onto flexible materials such as paper and cloth. Paper tape base is relatively hard and can be ground to a high gloss surface. Paper tape base sponge sandpaper is used in both precision grinding and ultra precision. Fabric tape base has higher strength than paper tape base, lower sensitivity to temperature and humidity, and will not lose stability due to increased temperature and humidity. The durability of fabric sponge sandpaper is much higher than that of paper sponge sandpaper. The commonly used abrasives in furniture production are alumina, silicon carbide, zirconia aluminum, garnet, while glass sand is used as the abrasive for handmade sandpaper, each with its own characteristics.

Generally speaking, sponge sandpaper is used as a grinding material for rough grinding, high plasticity, large grinding area, and to avoid chip embedding and softer workpieces; Fine grained materials are selected for precision grinding and harder workpieces. Abrasive is bonded to the substrate by a binder. Adhesive should have strength, elasticity, heat resistance, water resistance, etc. At present, the commonly used adhesives are animal glue and synthetic resin. Animal glue is not water-resistant, while synthetic resin has good water resistance. Waterproof sponge sandpaper uses water-resistant synthetic resin as the base adhesive and composite adhesive, and undergoes strict waterproof treatment. Based on the functions of the substrate, abrasive, and binder, and in combination with the processing object and process technology requirements, the appropriate substrate, abrasive particles, and binder can be selected to meet the requirements of sand grinding processing.
