abrasive paper
sandpaper
According to different abrasive substances, there are emery paper, artificial emery paper, glass sandpaper and so on. Dry abrasive paper (wood sandpaper) used to polish the surface of wood and bamboo. Water resistant sandpaper (water sandpaper) is used to polish the surface of metal or non-metal workpiece in water or oil.
Basic information
Commonly known as sand. A material used for grinding. Used to grind the surface of metal, wood, etc., to make it smooth and smooth, usually glued to the base paper with various abrasive grains. According to different abrasive substances, there are emery paper, artificial emery paper, glass sandpaper and so on. Dry abrasive paper (wood sandpaper) used to polish the surface of wood and bamboo. Water resistant sandpaper (water sandpaper) is used to polish the surface of metal or non-metal workpiece in water or oil. The base paper is made of unbleached sulfate wood pulp. The paper is strong, wear-resistant and folding resistant, and has good water resistance. The abrasive materials such as glass sand are adhered to the base paper with adhesives such as tree gum. [1]
Classification of sandpaper
In practice, the classification of sandpaper is not uniform.
Sponge sandpaper
Suitable for grinding smooth parts, all kinds of materials. Sponge sandpaper sanding process has the characteristics of high production efficiency, good surface quality and low production cost, so it has been widely used in furniture production. The final surface quality of furniture products has a close relationship with the sanding process. Sponge sandpaper is the main tool of sanding process.
Dry abrasive paper
Dry abrasive paper with synthetic resin as binder will be silicon carbide abrasive adhesive on the latex, and coated with antistatic coating made of high-grade products, with anti-blocking, anti-static, good softness, high wear resistance advantages. Available in a variety of fineness, suitable for sanding metal surfaces, putty and coatings. Dry abrasive paper is generally made of special kraft paper and latex paper, natural and synthetic resin as binder, and is manufactured by advanced high electrostatic sand planting process. This product has high grinding efficiency and is not easy to stick chips. It is suitable for dry grinding. Widely used in furniture, decoration and other industries, especially rough grinding.
Water abrasive paper
Also known as water resistant sandpaper or water sandpaper, because when in use can be immersed in water grinding or grinding in water named, water resistant sandpaper is water resistant paper or treated and water resistant paper as matrix, paint or resin as binder, corundum or silicon carbide abrasive firmly glued to the matrix and made of a kind of abrasive tools, the shape of page and roll two kinds. According to the abrasive can be divided into: brown alumina sandpaper; White corundum sandpaper; Silicon carbide sandpaper; Zirconium corundum sandpaper, etc. According to the binder can be divided into: ordinary binder sandpaper; Resin binder sandpaper.

Water abrasive paper texture is fine, water abrasive paper is suitable for grinding some texture more delicate things, and suitable for post-processing; Water abrasive paper the gap between the sand is smaller, the ground is smaller, and water when used together with the ground will be with the water flow out, so to use with water, if the water abrasive paper dry grinding then the ground will stay in the gap of the sand, so that the surface of the sandpaper light can not reach its original effect, and dry sandpaper is not so troublesome, It has a larger gap between the grains of sand and it has a larger amount of debris that will fall off during the grinding process because of the larger gap, so it doesn't need to be used with water.
Its characteristics are:
1. Using linkage line production, high efficiency;
2. Because water resistant sandpaper using varnish as binder, so the drying time is longer, the drying method is generally used hanging drying;
3. In general, the granularity of water resistant sandpaper is fine. The granularity of our water sandpaper is from P80, fine granularity is connected with the grain of metallographic sandpaper.
4. Water resistant sandpaper generally in water conditions for grinding operations, so less dust, good working conditions.
Dust-free mesh sandpaper
In the use of dust-free mesh sand grinding, can reduce the harm caused by harmful particles due to drift to the minimum.
Compared with traditional grinding materials, there is no plugging, which greatly extends the service life of the product; Very little caking, efficient vacuuming fundamentally solved the generation of caking; High efficiency, greatly reduce the replacement frequency of the sand dish, improve the work efficiency.
The type of sandpaper
The common ones are 400# 600# 1000# 1200# 1500# 2000#.
For example, W10 stands for # 04 sandpaper, 800 mesh. The specifications of other types of sandpaper are as follows:
