Performance testing
The surface resistance (according to standard: ANSI/ESD541-2008) and surface roughness of the ceramic hand models prepared in the above examples were measured to measure the antistatic ability and self-cleaning ability of the ceramic hand models, and the results are shown in tables 1 and 2.
TABLE 1
| Example number | 1 | 2 | 3 | 4 | 5 | 6 |
| Surface resistance | 3.6×10 6 | 4.4×10 6 | 4.9×10 6 | 6.1×10 6 | 5.8×10 6 | 8.8×10 7 |
| Roughness/mum | 0.27 | 0.33 | 0.31 | 0.23 | 0.26 | 0.54 |
TABLE 2
| Example number | 7 | 8 | 9 | 10 | 11 |
| Surface resistance | 1.4×10 8 | 6.6×10 7 | 2.4×10 8 | 3.7×10 8 | 6.9×10 6 |
| Roughness/mum | 0.72 | 0.58 | 0.69 | 0.63 | 0.47 |
