1：Inspection Date：2021.03.03
2：Sample Specification：Sandpaper P180 & Sandpaper P400
3：Testing Enterprise：DOMILL Abrasive
4：Testing Standard：GB/T 9258-2000
5：Samples Features：Both P180 and P400 were produced by using the high temperature calcined BFA
6：Physical Properties：
| Spec. | Sieve 1 | Sieve 2 | Sieve 3 | Sieve 4 | Sieve 5 | Undersize |
| P150 | 0 | 1.8 | 29.5 | 75.5 | 98.4 | 1.6 |
| GB/T | 0 | ≤3 | 20-32 | 66-84 | ≥96 | ≤4 |
| Settling Pipe | DS0 | DS3 | DS50 | DS95 |
| 400# | 86.68 | 69.21 | 48.2 | 37.48 |
| P400 GB/T | ≤81 | ≤53.9 | 33.5-36.5 | ≥25.3 |
| P320 GB/T | ≤94 | ≤66.8 | 44.7-47.7 | ≥34.2 |
7: Conclusion: The particle size composition of P180 is close to that of GB/T P150, and the particle shape is more regular, close to BMK. The particle size composition of P400 is close to that of GB/T P320, and the particle shape is general, close to ball mill.
