Characteristics And Functions Of Abrasive Material Sponge Sandpaper

Abrasive materials The types of abrasives, belt bases, binders, and processes of sandpaper are constantly improving. For some grinding processes such as water grinding sandpaper, dry sandpaper, sponge sandpaper, etc., it has the advantages of high production efficiency, good appearance quality of processed devices, and low production cost. Therefore, it has been widely used in furniture production. The final product quality of household products and grinding Craftsmanship have an inseparable relationship. Sponge sandpaper is the main tool in the sanding process.

Sponge sandpaper is a belt-shaped tool that is bonded to flexible materials such as paper and cloth with abrasive materials for grinding and polishing. The paper tape base is relatively hard and can grind out a high-gloss surface. Paper tape base sponge sandpaper is used in fine grinding and super fine grinding. The cloth tape base is stronger than the paper tape base, is less sensitive to temperature and humidity than the paper tape base, and will not lose stability due to increased temperature and humidity. Cloth sponge sandpaper is more durable than paper sponge sandpaper and Much taller. Abrasives commonly used in furniture production are alumina, silicon carbide, zirconia aluminum, garnet, and glass sand is used as the abrasive for manual sandpaper. These abrasives have their own characteristics.

Abrasive material Sponge sandpaper is generally used for coarse grinding, large plasticity, and large grinding area. In order to avoid embedded chips and soft workpieces, choose coarse-grained sandpaper; for fine grinding, hard workpieces, etc. choose fine-grained. The abrasive is bonded to the base by a binder. The binder 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 resin has good water resistance. Water-resistant sponge sandpaper uses water-resistant synthetic resin as the primer and compound glue, and undergoes strict waterproof treatment. According to the role of the tape base, abrasive, and binder, combined with the processing object and process technology requirements, the appropriate tape base, abrasive grains, and binder can be selected to meet the requirements of sanding processing.
