What Are the Main Differences Between Dry Sandpaper and Water Sandpaper?

Sand material of wet sandpaper is generally silicon carbide, and paper base of it is usually kraft paper. There are also more high-end, such as imported sandpaper, its paper base is mostly latex paper. The characteristics of latex paper are good flexibility, stronger surface adhesion of sand particles, which makes sand paper more durable, more uniform particles, and better polishing effect.

The clearance between sand grains of waterproof abrasive paper is small, and the debris produced by sandpaper is small. When used with water, the debris will flow out with the water, thus maintaining the sharpness of the sandpaper surface. If water sandpaper is used for dry grinding, the product debris will adhere to the gap between the sand grains, which will make the surface of sandpaper lose sharpness without grinding force. Thus, it can not achieve the effect of its use.

Sandpaper is widely used in hardware processing, stone grinding, die processing, automobile surface grinding, wall atomic ash grinding, paint removal, rust removal and other industries and types.

Dry sandpaper is also called dry sandpaper. Compared with waterproof sandpaper, the gap between sand grains of dry sandpaper is larger, and the debris produced by grinding is larger. Because of the large gap, the debris will fall off by itself in the process of using, so it does not need to be used with water. The sand grains of dry sandpaper are generally high quality silicon carbide, and the paper base is usually made of latex paper, so they have better flexibility, better heat dissipation in the use process and they are not easy to cause blockage.

Dry sandpaper is widely used in wood processing, precision die grinding, stone processing, synthetic material processing and other industries and types, especially in the wood processing and die grinding industry.
