The main purpose
It is used to measure the expansion force and degree of expansion when all kinds of textiles, non-woven fabrics, leather, medical materials, etc. are simultaneously stressed in all directions (elastic film method).
Technical parameter
1. Test area: 50cm2 7.3cm2
2. Measuring range: 0-2MPa, when the burst pressure is greater than 20% of the full scale, the accuracy is ±2% of the full scale; when the burst height is less than 70mm, the accuracy is ±0.02mm.
3. The minimum graduation value: 0.002MPa
4. Pressure rate: 100 -500cm2/min, accuracy: 10%
5. Maximum burst time: (99.9±0.1)S
6. Maximum expansion: (70±0.02) mm
7. The diaphragm should meet the following requirements: the thickness is less than 2mm;
8. Output form: print output, display output (including computer and printer)
9. The clamping device should provide reliable specimen clamping, so that there is no specimen damage, deformation or slippage during the experiment.
10. Power source: AC220V 50Hz
