Color Difference Of Abrasive Paper And Abrasive Belt

The common sand surfaces are white sand, red sand, and black sand. The white sand on the market is mostly used for polishing aluminum products, while the red sand is mostly used for woodworking products. The black sand is the same as the white sand, generally brown corundum, but its dyeing is different. From the perspective of wear resistance, pickaxe corundum is stronger than brown corundum and silicon carbide. The blue sand surface is calcined to make its wear resistance and high-temperature resistance stronger than ordinary sandpaper. Not only that, but also, a certain amount of pickax corundum is added to make the product wear-resistant and increase its cutting force.

Abrasive sandpaper is not necessarily expensive. Different sandpaper materials should be matched with sandpaper, such as wood products. Almost any sandpaper can be used for sanding. Generally speaking, the price of red sandpaper is low, and red sand is used. If iron parts need to be polished, although red sand and black sand can also be used to polish the effect, the consumption of sandpaper is too fast, and the cost increases. If calcined blue sand paper or products with the cost of pickaxe corundum are used, not only is the grinding effect better than red sand and black sand, but also the grinding times are longer, thus reducing the production cost.

Sandpaper with blue film sanding disc surface: After calcination, the sand surface has higher wear resistance and higher temperature resistance than ordinary sand surface sandpaper. The surface is coated to make it have a certain water resistance, which increases the scope of application. In addition, the sand grain cost of the sand surface is added with the pick corundum component, and the cutting force abrasion resistance is stronger than other sand surfaces.
