How To Make The Right Choice Of Sponge Sandpaper?

Sponge sandpaper is a ribbon that is bonded to a flexible material such as paper or cloth by means of a grinding and polishing abrasive.

Sponge sandpaper is composed of base material, abrasive and binder. The basic materials of sponge sandpaper for furniture production are cloth and paper. The paper tape base uses specially treated high-strength paper as sponge sandpaper. Paper-based sponge sandpaper is 1/3-2/3 lower than fabric-based sponge sandpaper. The paper base is relatively hard and can be ground to a high gloss finish. Paper-based sponge sandpaper for fine and superfine grinding. The cloth tape base has a higher strength than the paper tape base and is less sensitive to temperature and humidity than the paper tape base. It does not lose stability due to increased temperature and humidity. The durability of cloth sponge sandpaper is better than that of sponge sponge paper. much higher. Abrasives commonly used in furniture production are alumina, silicon carbide, zirconia aluminum, garnet and hand sandpaper. Glass sand is used as an abrasive. These abrasives have their own characteristics.

Coarse grinding, large plasticity, large grinding surface, coarse particle size, avoid chipping, soft workpiece, etc. Fine grinding is used for fine grinding and hard workpieces. The abrasive is bonded to the tape substrate by an adhesive. The adhesive should have strength, elasticity, heat resistance, water resistance, etc. Commonly used adhesives are animal glues and synthetic resins. Animal glue is not water resistant, and synthetic resin has good water resistance. Waterproof sponge sandpaper uses water-resistant synthetic resin as the base rubber and compound glue, and carries out strict waterproof treatment. According to the effect of the tape base, abrasive and binder, the appropriate tape base, abrasive particles and binder can be selected in combination with processing goals and process technical requirements.
