How To Choose The Right Sandpaper For Your Using?

Abrasive sand paper is an indispensable thing. Sandpaper is widely used. Various mold models such as mobile phones, automobiles, and wood products are indispensable. Secondly, sandpaper also plays an important role in the coating construction process. Sandpaper is generally divided into:

  • dry sandpaper
  • water sandpaper
  • sponge sandpaper

What they all have in common is the use of a bond to bond the different abrasive and sandpaper substrates together.
Sponge Sandpaper

Sponge sandpaper Sponge sandpaper is the main tool in the sanding process, suitable for sanding smooth parts, all kinds of materials can be used. The sponge abrasive sand paper sanding process has the characteristics of high production efficiency, good surface quality and low production cost, so it is widely used in furniture production. The final surface quality of furniture products is closely related to the sanding process.
Dry Sandpaper

Dry sanding paper uses synthetic resin as a binder to bond silicon carbide abrasives on the latex, and is coated with an antistatic coating to make high-end products. It has the advantages of anti-blocking, anti-static, good softness and high wear resistance. . Available in a variety of fines, suitable for sanding metal surfaces, wood surfaces, putties and coatings. Dry sanding paper is generally made of special kraft paper and latex paper, and natural and synthetic resins are used as binders. .

Dry sandpaper is also called dry sandpaper. The gap between the sand grains of dry sandpaper is large, and the grinding debris is also large. During the use process, the debris will fall off due to the large gap, so it does not need to be used together with water. The sand is generally made of high-quality silicon carbide, and the paper base is generally made of latex paper, so it has better flexibility, better heat dissipation during use, and is not easy to cause clogging. Dry sandpaper is widely used in wood processing, stone processing, precision mold grinding, synthetic material processing and other industries and types of work, and is widely used in furniture, decoration and other industries.
The application of dry sandpaper in the construction process of wood wax oil. In the process of wood wax oil construction, we often mention the sandpaper of different meshes used when grinding wood, and the dry sandpaper mentioned here is not water sandpaper. The auxiliary tools provided by Sangge in the construction of wood wax oil are water-resistant sandpaper. The primer and compound glue are animal glue, and the abrasive is brown corundum. It is suitable for wood surface processing and wall decoration. Specifications: about 215*280mm.
Water Sandpaper

Water sandpaper is also called water sandpaper, water-resistant sandpaper, that is, sandpaper that can be sanded with water. The grit material of water sandpaper is generally silicon carbide, and the paper base is usually kraft paper. There are also relatively high-end ones, and many of the paper bases are latex paper. The characteristics of latex paper are good flexibility and stronger surface adhesion of sand particles, so the sand paper is more durable, the particles are more uniform, and the polishing effect is better.

The gap between the sand grains of the water sandpaper is smaller than that of the dry sandpaper, and the debris of the ground items is also smaller. When used with water, the debris will flow out with the water, thereby maintaining the sharpness of the surface of the sandpaper. If the water sandpaper is used for dry grinding, the product debris will adhere to the gaps between the sand grains, so that the surface of the sandpaper loses its sharpness and has no grinding force. So that it can not achieve the effect of its use. Water sandpaper is widely used in stone grinding, hardware processing, mold processing, wall putty grinding, automobile surface grinding, rust removal, paint removal and other industries.

The above is the classification and usage scenarios of sandpaper. After reading it, you should be able to choose the right sandpaper for yourself.
