Methods of measure
Specific Surface Area: use MASTERSIZER analyzer produced by MALLVERN Company to measure it.
Average Particle Size: use MASTERSIZER analyzer to measure average particle size.
Residue on 325 mesh: put 1000g sample in 325 mesh to filtrate with wet method ,and then count the proportion of residue.
Bulk Density, Tapped: put 15g sample in 1000C.C measuring cylinder with scale, and then measure it after falling down 100 times from a height of 5cm.
Whiteness: use KETT brand C-100-3 model whiteness to measure it.
Sediment volume: put 15g sample in 100C.C. measuring cylinder with scale, and shake it after pouring the water reach the 100C.C, measure it about one hour later .
PH: use HI8520 model acidometer produced by Italy HANNA instrument factory to measure it. |
