Detailed description of cardboard - Determination of compressive strength

Cardboard compressive strength refers to the bearing capacity of cardboard when it is subjected to vertical pressure, and is usually used to evaluate the strength and durability of cardboard. This indicator is usually used in industries such as cartons and cardboard packaging materials.

Cardboard compressive strength can usually be determined by the following steps:

1. Prepare testing equipment: cardboard compressive strength testing machine, sample cutter, sample mold, weighing device.

2. Cut the cardboard sample into a sample of the specified size using a sample cutter and a sample die.

3. Put the sample into the cardboard compressive strength testing machine, and set it according to the equipment manual.

4. Before starting the test, measure the weight of the indenter with a weighing device and record it.

5. Place the sample to be tested on the test bench, and adjust the indenter of the testing machine to make it contact with the surface of the sample.

6. To start the test, apply pressure at a specified rate until the sample compresses or breaks.

7. Record the pressure and displacement data during the test, process the data, and calculate the compressive strength of the sample.

NBCHAO reminds you: when testing the compressive strength of cardboard, the consistency of the test environment should be maintained to avoid the influence of interference factors on the test results. In addition, care should be taken when testing to avoid injury from the test head or sample cutter. When determining the compressive strength, attention should also be paid to selecting appropriate test conditions and test methods, and following international standards, such as ISO 13821 and TAPPI T 804, etc.
