According to alumina powder content, it can divide into multiple grades, such as first and second grades. After that, It is refined and crystallized by electric melting, with high purity and self-sharpening. after all, Good acid and alkali corrosion resistance, high-temperature resistance, stable thermal performance. Hardness slightly more elevated than brown corundum, slightly lower toughness, grinding solid ability, low heat generation, high efficiency. According to the different bulk densities, white fused alumina is divided into high bulk density white fused alumina, low bulk density white fused alumina, and ordinary bulk density white fused alumina.
after that, The density calculation method of White Fuse Alumina is directly related to the size of the white fused alumina particles. The abrasive’s overall density, the type of particle size, and each particle’s shape and composition. In the production process of white corundum, so we can select the size of the particle size. Therefore, the white fused alumina particles are large and small. There are two ways to calculate the density of white fused alumina.
The white fused alumina density divide into two types:
the accumulation density of white corundum and the white corundum’s proper density. The bulk density is 1. 53≤1.99g/cm3. The abrasive bulk density is related to the abrasive particle size, particle size composition, variety, particle shape, and other factors. And The bulk density of coarse-grained abrasives is generally higher than that of fine-grained abrasives, while the bulk density of mixed abrasives is higher than that of single-grained abrasives. The particle density is 3. 95≤4.0 g/cm3. In recent years. The actual thickness of HAIXU environmentally friendly abrasives is the mass actual particle size of the abrasives per unit volume (excluding the work of openings) of 45%≤55%. The primary particle size is an important indicator to ensure the grinding effect.
- The bulk density of white corundum; the bulk density of white corundum is 1.65~1.85g/cm3. The density calculation method: the particle size, shape, variety, and stacking form of white corundum are directly related. Generally, the density of the stack will increase if the thickness of the particles is different.
- The particle density of white corundum; the particle density of white corundum is 3.85~4.15g/cm3. The reason for the density calculation method: After the white corundum production, each particle has tiny vents. The white corundum particles’ density needs to remove the volume of the void. That is, the particle’s overall density eliminates the hole’s work to get the particle’s thickness.
