According to the shape, the sandpaper can be divided into sandpaper and abrasive belt. The sandpaper is like the paper we use. It can be directly torn by hand. The reverse side of the belt is generally cloth. It is suitable for use with the grinding machine and is more durable.
According to different abrasive materials can be divided into dry sandpaper, water sandpaper, sponge sandpaper.
Dry abrasive paper is also called dry sanding paper. It is a synthetic resin as a binder. The silicon carbide particle abrasive is pasted on the latex paper. The gap between the sand particles is large, and the ground debris will fall off automatically, which is not easy to be polished. The phenomenon of clogging affects the grinding, and is suitable for grinding metal surfaces, wood surfaces, putty and coatings. Dry sandpaper is generally made of special kraft paper or latex paper.
Water sandpaper is also called water-sand paper, water-resistant sandpaper, abrasive material is silicon carbide, paper base is generally kraft paper, water sandpaper texture is smaller than the gap between fine sand particles, grinding debris particles are also small, together with water The use of debris will be washed out, so as not to affect the sharpness of the sand. Water sandpaper is suitable for polishing finer textures, and is suitable for post-processing, used in stone grinding, hardware processing, abrasive processing, automotive polishing and other industries.
Sponge sandpaper, also known as sponge sand, is a sponge-based substrate. It is filled with abrasive sand on the sponge. It is characterized by softness and elasticity, strong water absorption and reusability. It is widely used in solid wood processing and metal stainless steel processing. Grinding and polishing of surfaces such as mechanical manufacturing.
