Main purpose

Under laboratory conditions, evaluate the electrostatic characteristics of the sample after being charged in the form of friction, and use it in conjunction with a charge meter for the experiment of frictional electrification of the sample.

Technical indicators

1. The touch screen operation display of the drum friction machine automatically flips and does not require manual operation (there is no need to manually hold the sample in the middle to prevent interference from human factors). The drum friction machine is set to run for a certain time and automatically stops rubbing the sample when the time is up.

2. Inner diameter of drum: (65 ± 5) cm

3. Drum depth: (45 ± 5) cm

4. Drum speed: above 46r/min

5. Roller diameter: above 300mm

6. Material of drum lining: Polypropylene clear standard fabric (GB/T 7568.5-2002) or Nylon (choose one of the two friction fabrics for the drum)

7. Number of drum blades: 3 pieces

8. Air volume: above 2m3/min

9. Temperature heating: (60 ± 10) ℃

10. Dimensions: 900mm × 780mm × 2100mm (including bracket)
