Description
Abrasive Paper ( Sandpaper) is a kind of abrasive tool. It is used to clean and polish the surface of metal and non-metal materials. According to different grinding material,it includes emery paper, artificial emery paper, glass paper, etc. Dry abrasive paper (wood sandpaper) is used for polishing wood and bamboo surface. Water proof abrasive paper is used for polishing metal or nonmetal tools in the water or oil . Base paper is made from unbleached sulfate wood pulp ,which is strength, folding, wear-resisting and have good resistance to water. Stuck glass sand or other grinding material on base paper, then it will be abrasive paper.

Classification
*By Abrasive Grians Used
Brown Aluminum Oxide sand paper; White Aluminum Oxide sand paper; Silicon Carbide sand paper; Zirconium Aluminum Oxide sand paper, etc.

*By Bonding Materials
Ordinary binder sand paper; Resin binder sand paper.
There are coarse sand paper and fine sand paper.

*By Materials Polished
Wood sandpaper, namely dry sandpaper; Waterproof abrasive paper, namely water-resistant sandpaper; Iron cloth, it is a kind of dry abrasive paper, coarser, can be used to polishing metal surface quickly.

Common Sand Paper
Sanding Sponge
Sanding sponge process with high production efficiency, good quality of processed surface, low production cost, thus widely used in furniture production. The quality of furniture product surface has a close relationship with the final sanding process . Sanding sponge is the main tool for sand grinding process.

Dry Abrasive Paper
Dry abrasive paper puts resin as the binder.It is a high-grade coated abrasive by sticking silicon carbide abrasive on latex and coated with antistatic coating. Dry abrasive paper has many advantages:anti clogging, antistatic, soft, high wear resistance, etc. There are variety of fineness, suitable for grinding the metal surface, putty and coating.It is widely used in furniture, decoration and other industries, especially the coarse grinding.

Water proof abrasive paper
Waterproof abrasive paper, which can be used in the water. It is a grinding tool made by treating waterproof paper as the substrate, paint or resin as binder, then sticking the corundum and silicon carbide abrasive to the substrate.

Non-dust Sandpaper
In the use of non-dust sandpaper, the harm of floating harmful particles can be reduced to a minimum. Compared with traditional polishing materials, non-dust sandpaper has these advantages :
* No jam.
This feature extends the service life of the product greatly;
* Few agglomerate.
Efficient dust collection solves the agglomerate fundamentally;
* High efficiency,
Reducing sand disc replacement frequency greatly and improving the working efficiency.

Sandpaper Model
Commonly used with 400 # 600 # 1000 # 1200 # 1500 # 1200 #.
For example, W10 on behalf of 4 # sandpaper, 800 mesh

Abrasive belt
Abrasive belt is another kind of coated abrasives, called flexible abrasive. When polishing, it is more flexible and safety than abrasive grinding wheel. The advantages are higher precision and lower grinding cost.
