Burst resistance of paper compressive strength measurement

Bursting strength refers to the maximum pressure that a unit area of ​​paper can withstand under constant pressure until it breaks. This indicator is expressed through hydraulic or pneumatic pressure and reflects the extent to which the paper can withstand external pressure without breaking. As a special equipment, the bursting strength Tester plays an important role in paper production and quality control.

Definition and measurement method of bursting strength

Bursting strength is a key indicator of the compressive strength of paper, which is defined as the maximum pressure it can withstand per unit area. During the measurement, the paper sample is uniformly pressurized in the bursting strength Tester until it breaks. This measurement process can be represented by changes in hydraulic or pneumatic pressure.

Regular calibration and maintenance of instruments

In order to ensure the measurement accuracy of the bursting strength Tester, regular calibration is an essential step. The calibration of the instrument pressure gauge should make the error of the pressure indication value less than 1% to ensure the accuracy of the measurement results. In addition, it is necessary to pay attention to the parallelism of the upper and lower pressure rings to maintain the flatness of the sample pressure rings. The protruding state of the rubber membrane needs to correspond to the pressure indication on the pressure gauge to ensure that the resistance of the rubber membrane is moderate and can be restored in time. If the resistance of the rubber membrane is too great or cannot be restored in time, the rubber membrane needs to be replaced. There should be no oil or air leakage from each joint of the instrument to ensure the sealing of the instrument.

Instrument maintenance precautions

During the use and maintenance of the instrument, you also need to pay attention to the state of the rubber membrane to ensure that it is in good working condition. Each joint of the instrument needs to be checked regularly to prevent oil and air leakage. During the use of the instrument, the operator needs to operate it carefully to avoid artificial damage to key components. Regular maintenance work will ensure that the bursting strength Tester remains accurate and reliable during long-term use.

As a key measurement tool for the compressive strength of paper, the bursting strength Tester provides important support for paper production and quality control. Through scientific measurement with instruments, we can accurately understand the compressive properties of paper and provide a basis for the design and production of paper products. In the use and maintenance of the instrument, following standard operating procedures and regular maintenance will ensure the reliability and stability of the bursting strength Tester and provide strong technical support for the improvement of paper quality.
