The application range of white corundum in diamond abrasive is very wide. White corundum sand can be divided into white corundum section sand, white corundum grain size sand, white corundum fine powder, white corundum powder and other specifications. White corundum abrasive has been playing in our lives. It has a considerable effect. Although we don’t directly touch the raw materials of these abrasives, there are traces of it in the daily necessities and tools in life. Then the white corundum sand, grain size sand, fine powder, and micro powder in the emery abrasive Can you really tell the difference?
,
White corundum is made of high-quality alumina powder, which is refined and broken in an electric furnace. Its hardness is slightly higher than that of brown corundum, its toughness is slightly lower, its grinding ability is strong, its calorific value is small, and its efficiency is high. Good sharpness. It can be made into grinding wheel type abrasive tools, suitable for the grinding of high-speed steel, high-carbon steel and other steel material workpieces, and white corundum can also be made into fixed abrasive tools and coated abrasive tools, which can be applied to polishing, precision casting and other industries .

White corundum section sand
The white corundum section sand has high high temperature strength and good fire resistance and corrosion resistance, so it is often used as a refractory material. In addition, the white corundum section sand has strong slag resistance, so it can be used in industrial kilns. Or it can be made into ceramics and other by-products, and the products made by customers report that the effect is quite easy to use. Common white corundum section sand generally refers to white corundum products with particle sizes of 1-0mm, 3-1mm, 5-3mm, 8-5mm, etc.

White corundum grain size sand
White corundum is made from alumina powder with a high content of alumina as raw materials, and because of its more performance, it can be used in many fields, because the purity of white corundum itself is relatively high, and The hardness is also very good, and the wear resistance is also very strong, so the effect of using white corundum grain sand as an abrasive is very good. In fact, it can also be used as a fine-grain abrasive required for stainless steel. Emery abrasives such as black corundum and brown corundum have much better effects. White corundum grain sand can also be called single-size sand, and its grain size range is generally F12-F220, such as F12, F30, F54, F90, F100, F220, etc. White corundum sand is a kind of grain size sand, these two Models of products are mainly used in industries such as abrasives. The white corundum particle size sand also has the characteristics of acid and alkali corrosion resistance and good toughness. With the addition of some binders, it can be used to make white corundum grinding wheels.

White corundum fine powder
The fine white corundum powder is made of fused white corundum through special processing procedures. It has the characteristics of high hardness, slightly lower toughness, strong grinding power, high purity, and good eye sharpness. At the same time, the fine white corundum powder is mostly white. The commonly used particle sizes are 180-0 mesh, 220-0 mesh, and 240-0 mesh. And 325-0 mesh. It can also be called mixed sand. Take the 240-0 mesh mentioned above as an example. It refers to the white corundum abrasive with a mixed particle size of 240 mesh or more in the white corundum powder. It does not refer to all products. Granularity
For 240 mesh.
