Main purpose

This instrument is used to measure the wear resistance of woven fabrics, knitted fabrics, and non-woven fabrics (non-woven fabrics), and can also be used to measure the pilling performance of woolen fabrics under slight pressure.

technical parameter

1. Using a touch screen operation method, the circular sample is placed on the grinding head in the inverted mode required by the standard. Under the specified pressure, it comes into planar contact with the standard abrasive fixed on the grinding table, and undergoes multi-directional translational friction until the sample is ground to the specified number of times. The instrument automatically stops running.

2. The instrument can perform multi-directional translational motion to ensure uniform friction of the sample.

3. Friction head position: 4 workstations.

4. Sample clamp diameter: Φ 38mm ± 1mm and Φ 90mm ± 1mm.

5. Grinding table diameter: Φ 140mm+5mm.

 6. The total weight of the 38mm diameter specimen clamp and guide rod is (198 ± 2) g.

7. The total weight of the 90mm diameter specimen clamp, guide rod, and O-ring is (155 ± 1) g; The total weight of the 90mm diameter specimen clamp, guide rod, O-ring, and loading block is (415 ± 2) g.

8. Heavy hammer: 395g ± 2g, 594g ± 2g

9. The total mass of the loading block and sample fixture assembly is: large block (795 ± 7) g, which means the nominal pressure applied to the sample is 12 kPa; The small piece (595 ± 7) g represents a nominal pressure of 9 kPa applied to the sample.

10. The preset count ranges from 1 to 99999 times and can be set arbitrarily.

11. Test speed (grinding head speed): 47.5 ± 2.5r.p.m

12. Power supply: 220V ± 10%, 50Hz, 120W.

13. Other parameters shall be executed according to the standard.

14. Equipped with standard abrasives for machine adjustment and debugging.
