Due to the large changes in the technical indicators of the new standard GB12014-2009 "Anti-static Workwear", the roller friction machine that meets the previous standard completely does not meet the new standard, and the hardware cannot be upgraded on the original basis. Since this standard is a national mandatory standard, the drum friction machine must be updated. This machine is produced in response to the requirements of the national standard GB 12014-2009 "Anti-static work clothes" in Appendix B of the electrostatic charge test method. It is suitable for use by various product inspection departments, enterprises, schools and other research institutions that produce anti-static work clothes. When testing the frictional charging characteristics of garments, this machine is used to make the garments frictionally charged. It needs to be used in conjunction with the LFY-403 fabric frictional charging tester.
Instrument characteristics
1. All technical indicators of the instrument meet the standard requirements;
2. Set the running time of the roller friction machine to automatically stop the friction sample after the time is up;
Technical index
1. The inner diameter of the drum (65±5) cm;
2. The depth of the drum (45±5) cm;
3. The rotation of the drum is above 46r/min;
4. The cylinder diameter is more than 30cm;
5. The inner lining material of the drum is polyacrylonitrile standard cloth (GB/T 7568.5-2002)
6. The number of roller blades is 3
7. Air volume 2m³/min
