The role of sponge sandpaper
Sponge sandpaper is that finer 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, good appearance quality of the processed device, and low production cost. Therefore, it has been widely used in furniture production. The quality of the final product of the furniture product has an inseparable relationship with the grinding process. 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 by abrasives for grinding and polishing. The paper tape base is relatively hard and can be ground with a high-finish surface. Paper tape-based sponge sandpaper is used in both fine grinding and ultra-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, and will not lose its stability due to increased temperature and humidity. much higher. The commonly used abrasives in furniture production are alumina, silicon carbide, zirconia aluminum, garnet, and glass sand is used as abrasive for hand-made sandpaper. These abrasives have their own characteristics. Generally speaking, coarse grinding, large plasticity, large grinding area, to avoid chip insertion, soft workpiece, etc., use coarse particle size; fine grinding, hard workpiece, etc. use fine particle size. The abrasive is bonded to the tape 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, but synthetic resin has good water resistance. Water-resistant sponge sandpaper adopts water-resistant synthetic resin as primer and compound glue, and carries out strict waterproof treatment. According to the functions of the belt base, abrasives and binders, combined with the processing object and process technical requirements, the appropriate belt base, abrasive grains and binders can be selected to meet the requirements of sanding processing.
