About sandpaper

Commonly known as sand leather. A material for grinding. Sandpaper is an indispensable thing. Sandpaper is widely used. Various mold models such as mobile phones, automobiles, and wood products require sandpaper. Secondly, sandpaper also plays an important role in the coating construction process. According to the purpose, there are mainly the following categories

Sponge sandpaper

Suitable for grinding smooth parts, all kinds of materials are available. The sponge sandpaper sanding process has the characteristics of high production efficiency, good surface quality, and low production cost. Therefore, it is widely used in furniture production. The final surface quality of furniture products is closely related to the sanding process. Sponge sandpaper is the main tool of the sanding process.

Dry Abrasive Paper

Dry abrasive paper uses synthetic resin as a binder to bond silicon carbide abrasive to latex, and is coated with an antistatic coating to make a high-end product. It has the advantages of anti-clogging, anti-static, good flexibility, and high wear resistance. . A variety of finenesses are available, suitable for polishing metal surfaces, putty and coating. Dry sanding paper is generally made of special kraft paper and latex paper, natural and synthetic resins are used as binders, and manufactured through advanced high-static sand planting technology. This product has high grinding efficiency and is not easy to stick to debris. It is suitable for dry grinding. . It is widely used in furniture, decoration and other industries, especially rough grinding.

Water matte paper

Also known as water-resistant sandpaper or water-resistant sandpaper, it is named because it can be immersed in water or sanded in water during use. An abrasive made of corundum or silicon carbide abrasives firmly adhered to the substrate. Its shape has two types: sheet and roll. According to the abrasive points, it can be divided into: brown corundum sandpaper; white corundum sandpaper; Silicon Carbide Sandpaper; zirconium corundum sandpaper. According to the binder, it can be divided into: ordinary binder sandpaper; resin binder sandpaper.

The texture of water matte paper is relatively fine. Water matte paper is suitable for polishing some finer textures and is suitable for post-processing; water matte paper has smaller gaps between the sand grains and produces smaller pieces. When used with water The dust will flow out with water, so use it together with water. If you use water sandpaper dry grinding, the dust will stay in the gap between the sand grains, so that the surface of the sandpaper will be lightened and it will not achieve its original effect. Sandpaper is not so troublesome. The gap between the sand grains is larger and the crushed powder is also larger. During the grinding process, the crushed powder will fall off due to the large gap, so it does not need to be used with water. Its characteristics are: because the water-resistant sandpaper uses varnish as the binder, the drying time is longer, and the drying method is generally suspended drying; the water-resistant sandpaper generally has a finer particle size, and the fine particle size is connected with the grain of the metallographic sandpaper. Water-resistant sandpaper is generally sanded under hydrated conditions, so there is less dust and good working conditions.

Dust-free net sandpaper

The use of dust-free mesh sand for polishing can minimize the harm caused by harmful particles due to airflow. Compared with traditional sanding materials, there is no clogging. This feature greatly prolongs the service life of the product; minimal agglomeration and efficient dust collection fundamentally solve the generation of agglomeration; extremely high efficiency, greatly reducing sand The frequency of disc replacement improves work efficiency.
