Methods to Distinguish Polishing Material Abrasive Paper

Polishing material abrasive paper as the most common and most widely used abrasives tools, is divided into disc abrasive paper and sponge abrasive paper. We still need to distinguish rough and fine abrasive paper, and its water resistance or dry grinding. They are different in the workpiece production. The stand or fall of abrasive paper of polishing materials directly affects the quality of the products.

Therefore, the selection for appropriate and good polishing material abrasive paper, is very important, and we also must have a detailed understanding about it.

Disk sandpaper of different fields have different classification methods, which can be in accordance with the purpose to distinguish, and also according to the name of commodity, or according to different abrasives to distinguish, and even it can be carried out in accordance with the binder.

Firstly, to distinguish according to the abrasives: polishing materials brown fused alumina abrasive paper; White fused alumina abrasive paper; Silicon carbide abrasive paper; Zirconium corundum abrasive paper, etc.

Secondly, to distinguish according to the utility: dry abrasive paper (wood sandpaper) used for polishing wood, bamboo, metal, or other objects surface; Water proof abrasive paper (waterproof abrasive paper) used for water or oil polished metal or nonmetal workpiece and surface polishing.

Thirdly, to distinguish according to the name of commodity: wood abrasive paper, namely dry sandpaper; Waterproof abrasive paper, namely water-resistant sandpaper; iron sand cloth, a kind of dry abrasive paper, which is coarser and can be polished metal surface as soon as possible.

Finally, to distinguish according to the binder: ordinary binder polishing material abrasive paper; Resin binder abrasive paper. There are coarse and fine abrasive paper.

Precautions for Production processes:

A. The mismatch of base paper and adhesive. In the base paper production process it makes corresponding adjustment process, but the using process is not the same with coated abrasives polishing materials production enterprises, but it is not suitable as a sand binder for low degree of strength material, otherwise it will affect the wear resistance capability. If the improper control happens in abrasive paper production process, there will be brittle, cracked, mortar and paper stripping phenomenon.

B. The granularity of different degree of abrasive paper with different base paper, the selection for coarse mesh focuses on the base paper.

On the surface sliding degrees of base paper, the paper smoothness should be higher due to tiny sand and less glue quantity, so the paper surface can't have loose surface fibers on paper. While the coarse mesh has loose requirements relatively.
