Particle sizes for the recorded sample and sampling time.
Sample assessment
Glass fibre requires a distinction between measured particle distribution and actual fibre length. The micron-scale endpoint does not establish a nanofibre morphology. The laboratory test record documents this preparation only; applying the method to another batch requires a matched trial.
Recorded objective
Prepare powder in the micrometre or nanometre range.
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 | 250 mL alumina jar; 15–3 mm zirconia balls; 10 g glass fibre; alcohol wet milling; speed setting 480. |
| 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
After 2 hours of wet planetary milling, the sample measured D50 = 3.28 µm and D90 = 8.67 µm. The record supplies no initial distribution, fibre-length analysis, recovered mass or measured temperature.
Measured after 2 hours for the 10 g glass-fibre wet preparation.
Interpretation
The measured distribution supports the micrometre option in the stated objective. It does not establish a nanometre result or directly describe fibre length and aspect ratio. A distribution measured on a fibrous material requires the measurement and dispersion method to be retained for comparison.
Practical precautions
Contain fibres during handling and confirm the solvent-compatible operating arrangement. Add microscopy or a fibre-length method if morphology is the acceptance criterion, and check media wear before using the powder for composition-sensitive work.
TENCAN alternatives to evaluate
For follow-up comparison, consider the TENCAN Laboratory Full-Directional Planetary Ball Mill. For glass fibre, a matched QXQM trial can test whether changing orientation affects glass-fibre length and size distribution with separate measurement methods. 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.
