How to test the bursting strength of the corrugated board bursting test machine

Corrugated cardboard is the main packaging material, loved for its degradable and renewable properties. The bursting strength of corrugated board reflects the carrying capacity of the box during handling, loading and unloading, impact and tearing during circulation. China GB/T6545 \"Determination of the bursting strength of cardboard\", ISO2759 \"Determination of the bursting strength of cardboard\", GB1539 \"Determination of the bursting strength of cardboard\" and GB/T6544-2008 \"Corrugated cardboard\" all have requirements for bursting strength. Must be tested. The following is a brief introduction to the test method of corrugated board bursting strength:

1. The test method of the corrugated board burst tester: According to GB450, the area of ​​the intercepted sample should be larger than the burst tester\'s chuck. Samples must not have any watermarks, crush marks or visible damage. It is important not to use the sample held by the chuck in the test.

2. Burst testing equipment for corrugated cardboard; ASR-8502 Corrugated cardboard burst tester can be used

The burst resistance of corrugated cardboard. This instrument, also called corrugated board bursting strength tester, uses the automatic operation of a microcomputer, automatically judges the bursting strength, automatically presses down and memorizes the test results, and has a high degree of automation.

3. Corrugated board burst tester_Experimental principle of corrugated board burst tester; place the sealing sample on the film, clamp it with a sample clamp, and then apply pressure evenly to release the sample and film until the sample breaks. The bursting strength of the sample is the maximum value of the applied hydraulic pressure.

4. Corrugated Burst Tester_Corrugated Burst Tester Experimental Procedures:

1. Samples must beloaded under the atmospheric conditions specified in GB10739 and tested.

2. Open the sample clamp, clamp the sample between the two sample clamps, and then start the corrugated_corrugated cardboard burst tester, with (170 ± 15) ml / min to gradually increase the pressure.

3. When the sample bursts, read the indicated value on the pressure gauge. Then release the chuck and return the reading pointer to the starting position.

4. When the sample shifts visibly, the data should be discarded.

5. The results show that the determination was made using 10 samples attached to the front adhesive film and 10 samples to the back, and represent the arithmetic mean (kpa) of all measured values.

5. Summary;

The bursting strength of corrugated board refers to the maximum pressure that the corrugated board can withstand in a unit perpendicular to the surface of the suffi ciently under testomconditions. Corrugated Board Burst Tester_ASR-8502 Corrugated Board Bursting Tester It can be used to test the bursting strength of corrugated board. This instrument, also called corrugated board bursting strength tester, uses the automatic operation of a microcomputer, automatically judges the bursting strength, automatically presses down and memorizes the test results, and has a high degree of automation.
