Difference Between Water Sandpaper And Dry Sandpaper

1. The gap between the sand grains of the water scrub paper is small, and the grinding powder is also small. When used with water, the crumbs will flow out with the water, so use it with water. If the water sandpaper is used for dry grinding, the fines will remain in the gaps between the sand grains, which will dull the surface of the sandpaper and fail to 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 does not need to be used with water because the fines will fall off during the grinding process due to the large gap.

3. The water sandpaper grinds more slowly, but the grinding is smoother (the finer the water sandpaper, the slower and smoother the grinding). Dry sandpaper grinds faster but produces a coarser finish (coarser dry sandpaper grinds faster and coarser).

4. Dry sandpaper is used to polish metal products. Water sandpaper is used to sand higher-grade paints.

5. The water sandpaper is finer, and the back is paper. Dry sandpaper is coarser, and the reverse side 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.

7. Dry sandpaper is generally made of special kraft paper and latex paper, and natural and synthetic resins are used as binders. It is made by the advanced high-static sand-planting process. This product has the characteristics of high grinding efficiency and is not easy to stick. grind. Widely used in furniture, decoration, and other industries, especially for rough grinding.
