Sandpaper is divided into various types based on the materials used for sanding, including diamond sandpaper, artificial diamond sandpaper, glass sandpaper, dry sandpaper, and other types.



Classification of sandpaper


In practical life, the classification of sandpaper is not consistent, mainly divided into the following


1. Sponge sandpaper


This type of sponge sandpaper is primarily suitable for polishing and lubricating round parts, and various materials can be used.


The sanding process of sponge sandpaper has the characteristics of high production efficiency, good surface quality of processed objects, and low production costs, especially in the furniture industry, which is widely used in production. The final surface quality of furniture products is closely related to the sanding process, and sponge sandpaper is the primary tool for sanding processing.


2. Dry sanded paper


Dry sanding paper is made by using synthetic resin as the binder, then bonding silicon carbide abrasive onto the latex, and then applying anti-static coating. This type of sandpaper has the advantages of anti clogging, anti-static, good softness, and high wear resistance. It has a variety of fineness options and is suitable for polishing metal surfaces, putty, and coatings. Dry sanding paper is generally made of special Kraft paper and latex paper, natural resin and synthetic resin as binders, and advanced high electrostatic sanding techniques. This product is widely used in industries such as furniture and decoration due to its high grinding efficiency and low adhesion to chips.


3. Water resistant sanding paper


The texture is delicate, and water sanded paper is suitable for polishing some delicate things and for post-processing processing.


The gap between sand particles in water sanded paper is small, and the grinding debris is also small. When it is used with water, debris will flow out with the water, so it should be used with water. If water resistant sandpaper is used for dry grinding, debris will stay in the gaps between the sand particles, causing the surface of the sandpaper to become shiny, thus not achieving its original effect. And dry sanding paper is not that troublesome, and the gap between the sand particles is large, resulting in larger debris. During the polishing process, debris entering will also fall off due to the large gap, so it does not need to be used together with water.
