Applications
This machine is suitable for cracking strength testing of cardboard, cloth, leather, etc.
Principle
This machine uses signals to transmit pressure and automatically retains the maximum rupture strength value when the sample breaks. Place the sample on the rubber mold, clamp the sample by air pressure, and then the motor applies pressure evenly to make the sample and the rubber film bulge freely until the sample ruptures. The maximum value of the applied hydraulic pressure is the sample resistance. Bursting strength value.
