Table 1. Physical properties and printing indicator of PCL solvent ink at a temperature of 25 °C, 30 °C and 35 °C.
Temperature (°C) | Nozzle Diameter (μm) | Density (g/cm3) | Viscosity (mPa.s) | Surface Tension (mN/m) | Z |
---|---|---|---|---|---|
25 | 21 | 1.03 | 3.29 | 33.9 | 8.21 |
30 | 21 | 1.03 | 3.07 | 33.6 | 8.98 |
35 | 21 | 1.03 | 2.75 | 32.9 | 9.88 |
Viscosity and surface tension data are expressed as the mean, n = 3–4.
