The density of white corundum is divided into bulk density and particle density. Many users do not know the difference between the two, so the following will introduce the two to facilitate users to distinguish.
1. The bulk density is: 1.53-1.99g/cm3. The bulk density of the abrasive is related to the particle size, particle size composition, variety, particle shape and other factors of the abrasive. Generally speaking, the bulk density of coarse-grained abrasives is higher than that of fine-grained abrasives. The bulk density of particle size abrasives is greater than the density of a single particle size.
2. The particle density is: 3.95-4.0g/cm3. The true density of the abrasive refers to the mass of the abrasive contained in the unit volume (excluding the volume of the open pores).
The above is the introduction of the bulk density and particle density of white corundum. According to the introduction, it is more convenient for users to distinguish better, so as to help users use it.
