What abrasives is used for sandblasting titanium alloy workpieces? White fused alumina F180#mesh
White fused alumina is a common titanium alloy sandblasting abrasives with the characteristics of high hardness, uniform particle shape, and easy cleaning. It has higher grinding efficiency, which can shorten working time and the amount of abrasive used. In addition, white corundum has certain advantages in the processing of titanium alloy materials, and has better grinding effect on the deeper parts of some titanium alloy materials.
White fused alumina uses high-quality alumina powder as raw material, smelted in an arc furnace at a high temperature of 2200 degrees to fully melt it, and then cooled naturally or cooled by water to fully crystallize the smelted alumina liquid. After the alumina powder is fully smelted, crystallized and cooled, it becomes the original block of white corundum. After the original block of white fused alumina is crushed by a jaw crusher, it is deeply screened in a five-screen vibrating screen in strict accordance with industry standards to obtain white corundum sand of different sizes. The proportion of basic particles and mixed particles in our factory’s particle size sand far exceeds the national standard, the particle size is more concentrated, and the use effect is better.
The Al2O3 content is above 99%, and its hardness is higher than brown fused alumina, but its toughness is not as good as that of brown corundum. The Fe2O3 content of white corundum is very low, which is suitable for sandblasting operations where iron residue is strictly prohibited. At the same time, the material of white corundum is relatively hard, which is suitable for sandblasting with most sandblasting machines. It is also used as grinding and polishing materials, precision casting sand, spraying materials, chemical catalyst carriers, functional ceramics, refractory materials, etc.
