- Conclusions:
- According to ISO 2926:2005, the mass fraction of particle sizes of CR SB87 were determined to be 0.24% in more than 500 μm particle size, 2.21% between 355 and 500 μm particle size, 9.39% between 250 and 355 μm particle size, 25.02% between 212 and 250 μm particle size, 4.79% between 180 and 212 μm particle size, 29.95% between 100 and 180 μm particle size, 18.70% between 53 and 100 μm particle size and 9.18% in less than 53 μm particle size.
The mass median diameter is 100 ~180 μm. - Executive summary:
This test using the procedures outlined in the ZCTC Study Plan for PCF2017-004 and ISO 2926:2005. With a sieve shaker, a certain mass of the sample is sieved through a series of sieves with various aperture size. Each mass of the separate fractions retained in the sieve is weighed and the mass distribution of the particle sizes could be calculated. The relative differences between the sum of all masses and the mass of the sample taken were both less than 1.5%. Therefore, all results were available.The mass fraction of particle sizes of CR SB87 were determined to be 0.24% in more than 500 μm particle size, 2.21% between 355 and 500 μm particle size, 9.39% between 250 and 355 μm particle size, 25.02% between 212 and 250 μm particle size, 4.79% between 180 and 212 μm particle size, 29.95% between 100 and 180 μm particle size, 18.70% between 53 and 100 μm particle size and 9.18% in less than 53 μm particle size.
