The puncture strength of corrugated cardboard refers to the work required to pass through the cardboard with a specific shape of the corner cone, which includes the sum of the work required to start the piercing, tear the cardboard and bend into the hole, expressed in J.After the cardboard is made into cartons or other containers, it is inevitable to be bumped in the process of use or transportation. In order to resist this effect and avoid damage, the cardboard is required to have sufficient impact strength. For the determination of the impact resistance of the paper, the puncture strength can reflect the resistance of the corrugated cardboard to withstand the impact of sharp objects, which is an important dynamic strength performance index.
This instrument is corrugated cardboard anti-punctation performance (both punctation strength) special test instrument, with fast pressing, operation handle automatic reset and reliable safety protection, with liquid crystal display, thermal printer and other characteristics, wide range of application, is paperboard, paperboard, carton production, scientific research and commodity inspection enterprises and departments indispensable commonly used instruments.The machine adopts the advanced electronic control and computer technology, the various performance improved obviously, more accurate than put needle puncture strength testing machine, low power consumption, speed, etc. At the same time, the LCD display is clear and clear, and the cardboard pressing device is human and flexible. The operation is simple and fast, and the micro printer prints the test report, which is a high-tech product of mechatronics."
