5.1 Preparation of test specimens
5.1.1. The test sample placed in an oven at 110 0 C and dried at a temperature of 1 hour, cooled to room temperature before measurement.
5.1.2. The test sample divided into thirds, removing one of which measuring bulk density, and the other two aside.
5.2 Measurement procedures
5.2.1 The best at room temperature (23 ± 2) 0 C; relative humidity is detected at (50 ± 6)% of the environment.
5.2.2. The test sample into the instrument of the funnel, the test specimen under its own stacking interactions in a stable state.
5.2.3. Press the electrical control part of the power switch, power indicator light. Then press electrical control vibration switch, then vibration indicator light, electromagnetic oscillator to work. Powder under the action of electromagnetic vibrations to specific ways and means of measuring flows into the bucket. inflow powder should be smooth, continuous process and there are rules.
5.2.4. When measuring soot accumulation in the center of the barrel, and a barrel higher than the measured upper edge 2cm ~ 3cm When pressed again electrical control vibration switch, the electromagnetic oscillator is stopped. Press again to electrical control power switch, turn off the power.
5.2.5. Remove the shield, should be careful not to remove the rest of the collision.
5.2.6. Will accumulate in the measuring bucket on top of the powder scraped with a straight blade, scraping the barrel when the angle between the blade and the measuring surface about 450 This process should prevent the compaction of powder measuring cylinder to avoid vibrations.
5.2.7. Indexing is not greater than 0.01g Weighing scales measuring quality powder keg and barrel, and then subtracting the measured quality of the barrel, the barrel fine powder derived measurement quality.
5.2.8. Measurement process, powder flows into the measurement time should be controlled in the tub 30 Sec to 90 Between seconds powder inflow time by the amplitude of the electrical part of the adjustment knob to adjust the controls, adjust the funnel to the bottom surface of the guide groove distance between the vibration can also affect the inflow velocity Powder.
5.2.9. Throughout the measuring process, we should always avoid vibration measurements barrel.
5.3. data processing
Bulk density is calculated as follows:
PB = M1 / V
Where: P B - Powder bulk density, unit: g / cm3;
M1 - Quality measuring cylinder powder, unit: g;
V - the volume of the measuring cylinder, unit: cm3.
5.4. Follow the steps 5.2.1 - 5.3 Bulk density measurements other duplicate samples.
