Sample assessment
The black ink formulation combines dispersion liquid and powder. Intermediate withdrawals change the charge and should remain part of the preparation history. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Process for 2 hours and record the endpoint distribution.
Equipment and selection
The recorded planetary machine is XQM. The corresponding TENCAN family is the Vertical square planetary ball mill. The jar volume identifies the test container and does not establish an exact machine variant or production capacity. Equipment association follows the recorded machine designation.
Test setup
| Recorded planetary machine | XQM |
|---|---|
| Documented setup | 500 mL PTFE jar; 600 g of 3 mm zirconia balls; 120 g dispersion liquid plus 80 g powder; wet milling; speed setting 500. |
| Recorded operating cycle | Run 5 / pause 1; units not stated in mode field |
Speed values are reproduced as recorded settings. A rotational unit and planetary-disc versus jar-speed basis are not stated, so these numbers are not labelled rpm.
Recorded procedure and results
The black formulation was sampled at 30 minutes and 1 hour, with 10 g removed at each of these times. The 2-hour sample measured D50 = 15.13 µm and D90 = 25.98 µm. The test record title refers to two inks, but detailed measurements are supplied only for the black formulation.
Interpretation
The supported article concerns the documented black-ink experiment. Its endpoint is a measured process outcome, without a numerical size acceptance limit. The two 10 g removals changed the charge over time and should be considered when attempting a direct repeat.
Practical precautions
Preserve the powder-to-liquid ratio and record all sample withdrawals. Assess viscosity, dispersion stability and contamination separately before treating the measured distribution as evidence of finished-ink quality.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Laboratory Full-Directional Planetary Ball Mill. For black ink formulation, a matched QXQM trial can test whether changing orientation affects the black-ink distribution with the same sample withdrawals. Keep sample mass, media and sampling times controlled. This is a proposed comparison; the test record does not demonstrate a superior result for that alternative. Confirm jar compatibility and the permitted complete loaded mass before selecting a configuration.
Procedure records XQM; related product is the corresponding tested machine family. Exact variant is not inferred from jar size.
