The difference between water sandpaper and dry sandpaper
1. The gap between the sand grains of the water sandpaper is small, and the ground powder is also small; when used with water, the powder will flow out with the water, so it should be used with water; if you use water sandpaper for dry grinding The fines will remain in the gaps between the sand grains, which will dull the surface of the sandpaper and not achieve its original effect.

2. The gap between the sand grains of the dry sandpaper is large, and the grinding powder is also large; it will fall off due to the large gap during the grinding process, so it does not need to be used with water.

3. The water sandpaper grinds slowly, but the grinding is smoother (the finer the water sandpaper, the slower and smoother the grinding); the dry sandpaper is quicker, but the grinding is coarser (the coarser the dry sandpaper, the more polished it is. faster and thicker).

4. Dry sandpaper is used to polish metal products; water sandpaper is used to polish higher-grade paints.

5. The water sandpaper is finer, and the back is paper; the dry sandpaper is thicker, and the back is cloth.

6. Water sandpaper plays a great role in model making. It can eliminate the nozzle of the part, grind the gap of the part, and make the gap smooth and so on. In some cases, finer sandpaper can be used to polish parts with oxide layers to remove the oxide layers of metal parts, which can restore the metal parts to their original metallic luster.
