The common differences in color between sandpaper and sand belts 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 composition of black sand is the same as that of white sand, usually brown corundum, with different dyeing. From the perspective of wear resistance, pickaxe corundum is stronger than brown corundum and silicon carbide. The blue sand surface of Juhua Material (Manager Li 15377713863) has been calcined, making its wear resistance and high temperature resistance stronger than ordinary sandpaper. In addition, their product has also added a certain amount of pickaxe corundum, making its wear resistance and cutting force better
How to choose sandpaper, it may not necessarily be expensive or good. Different sanding materials should correspond to sandpaper, such as sanding wood products. Almost any sandpaper can be sanded. Generally speaking, the price of red sandpaper is relatively low, so red sandpaper should be used. If you want to polish iron parts, although using red sand and black sand sandpaper can also achieve results, the consumption of sandpaper is too fast and the cost increases. If you use calcined blue sandpaper or products containing the cost of pickaxe corundum, not only will the polishing effect be better than red sand and black sand, but the polishing frequency will be more, thereby reducing production costs

In terms of professional level of polishing, Juhua has been engaged in surface treatment for over 20 years and has abundant experience. Juhua materials are not only professional but also affordable. Juhua always adheres to the concept of "assisting manufacturing in China".

Blue sand surface sandpaper: After calcination, the sand surface has a higher wear resistance and high temperature resistance than ordinary sand surface sandpaper. The surface is coated to give it a certain degree of water resistance, increasing its applicability. Moreover, the cost of sand particles on the sand surface includes the addition of pickaxe corundum, which makes the cutting force and wear resistance stronger than other sand surface sandpaper
