Fracture Tester for Geomembranes
BACKStandards:
ASTM D 5397 - 93
Applications:
Product Information:
- Test 20 specimens at a time
- Stainless - steel bath
- Solid - state temperature controller
- Circulating pump
- Automatic low - liquid - level trip
- Bath cover to reduce evaporation
- Movable weight container
- Digital timer and micro - switch
- Bath motor drive device
The fracture tester applies continuous pressure to high - density polyethylene geomembrane materials under accelerated environmental conditions. Use a precision scribing device to mark dumbbell - shaped specimens.
Place the specimens on the tester and apply pressure to the samples through a container filled with lead weights, which is placed on a lever device. Put the samples in a bath containing a surfactant. The bath solution is maintained at 50°C, and the lifting of the bath is driven by a motor.
The fracture time of each specimen is recorded by a separate timer.
The bath and specimen fixing devices are made of refined stainless steel. The bath solution's correct temperature is maintained by a solid - state temperature controller and a heater at the bottom of the bath. The bath cover can reduce the evaporation of the bath solution.
A pump is used to maintain the consistency of the bath solution's temperature and concentration.
There is a low - liquid - level protection switch in the bath. When the liquid level is lower than the set value, the heater and the pump automatically stop working.
A high - liquid - level protection switch is optional.
