Brown aluminum oxide is mainly used in sandblasting rust removal, polishing and grinding, coated abrades, wear-resistant floor, water knife cutting, functional fillers, refractory materials, castable and other aspects, according to different uses, how to choose brown corundum particle size and grade? Let's take a look at it.
Brown aluminum oxide particle size, grade selection:
1. As a refractory castable, such as steel mills, ironworks brown corundum as a filler smelting furnace or as a coating for smelting furnacesour particle size requirements can be less accurate to pure sand, just select the segment sand, the common particle size of the segment sand is: 0-1mm, 1-3mm, 3-5mm, 5-8mm, according to the different selection of different segment sand.
2. As a coated abrasive tool, that is, to make emery cloth sandpaper belt, according to different process requirements, the commonly used brown corundum fine powder particle size is: 80 mesh, 100 mesh, 120 mesh, 180 mesh, 200 mesh;
3. When used for polishing and grinding, such as polishing of mechanical appearance, glass appearance, beautification of handicraft disposal, commonly used brown aluminum oxide powder particle size is mostly: 220 mesh, 240 mesh, 325 mesh, 500 mesh, 800 mesh;
4. As a wear-resistant floor, such as school playgrounds, parking lots, park squares and other needs, the third grade brown corundum with lower alumina content can be selected.
According to the different particle size of brown fused alumina, the price of different grades will be very different, in the future, when choosing brown corundum, we must choose the appropriate particle size and the appropriate grade, otherwise the use of large materials or small materials is a kind of cost, in order to save costs, we must choose the appropriate brown corundum used by my enterprise
