The Revolution Temperature Control option can heat samples from room temperature up to 250 degrees Celsius while running flow tests. Samples can be heated moving constantly, moving intermittently or not moving. Tests can be performed before heating and at temperature intervals.
Example Test Data
| Sample | 26C | 110C | 135C |
|---|---|---|---|
| Polymer | Avalanche Angle 51.8 deg | Avalanche Angle 60.1 deg | Avalanche Angle 68.2 deg |
| Density 0.436 g/cm3 | Density 0.379 g/cm3 | Density 0.372 g/cm3 | |
| Polymer Annealed | Avalanche Angle 50.5 deg | Avalanche Angle 58.0 deg | Avalanche Angle 63.3 deg |
| Density 0.438 g/cm3 | Density 0.390 g/cm3 | Density 0.383 g/cm3 |
A polymer was tested at 26C, 110C, and 135C to determine flow changes with temperature between annealed and non-annealed. Increases in temperature caused the powders to flow more poorly and this resulted in a lower powder bed density. In this case the annealed material showed more flow temperature resistance than the non-annealed material.
