The general sandpaper label is 30, and the fine is 30 mesh. No. 60, the fineness is 60 mesh. The label is No. 400, and the fineness is 400 mesh.

The sandpaper manufacturer added that the difference between fine sandpaper and coarse sandpaper There are the following two points :
1. The friction force is different. The friction force of the sandpaper depends on the number of holes in the screen. The number of holes in the coarse sandpaper is small, and the friction force is large; the friction force of the fine sandpaper is relatively small.
