Sponge sandpaper is a relatively fine material. The belt base of sponge sandpaper, the type of abrasive, the production process of sponge sandpaper, and the binder of abrasive are constantly improving. The grinding process of sponge sandpaper has the advantages of high production efficiency, making the appearance of the processed device good, and low production costs. Therefore, it has been widely used in furniture production. The final quality of furniture products has an inseparable relationship with the grinding process. Sponge sandpaper is the main tool of the sanding process. Sponge sandpaper is a band-shaped tool that is bonded to flexible materials such as paper and cloth by abrasives for grinding and polishing. The paper tape base is relatively hard and can grind a high-gloss surface. Paper tape base sponge sandpaper is used in both fine grinding and super fine grinding. The cloth tape base has higher strength than the paper tape base, and is less sensitive to temperature and humidity than the paper tape base. It will not lose stability due to increased temperature and humidity. The durability of the cloth sponge sandpaper is better than that of the siblings. Much taller. The abrasives commonly used in furniture production are alumina, silicon carbide, zirconium aluminum oxide, garnet, and handmade sandpaper, and glass sand is used as abrasives. These abrasives have their own characteristics. In general, coarse grinding, large plasticity, large grinding area, coarse particle size are used to avoid chipping, and the workpiece is soft, etc. Fine particle size is used for fine grinding and hard workpiece. The abrasive is bonded to the tape base by a binder. The adhesive should have strength, elasticity, heat resistance, water resistance, etc. At present, the commonly used binders are animal glue and synthetic resin. Animal glue is not water resistant, and synthetic resins have good water resistance. Water-resistant sponge sandpaper uses water-resistant synthetic resin as the primer and compound, and is strictly waterproofed. According to the role of the belt base, abrasives, and binders, combined with the object of processing and technological requirements, the appropriate belt base, abrasive particles and binders can be selected to meet the requirements of sanding processing.
