Cardboard detection method of interlayer bonding strength Tester

The interlayer internal bond strength Tester also has important application value in the manufacture and use of gray cardboard. Gray cardboard is a kind of cardboard with a large thickness and certain hardness and strength. It is mainly used to make packaging boxes, book covers, stationery boxes, etc., and has good durability and compression resistance. The internal bonding strength Tester can help manufacturers and users understand the internal bonding strength of gray cardboard, so as to improve the quality and reliability of gray cardboard.

In the application of gray cardboard, the internal bond Tester can be used to test the bond strength between different layers, as well as the overall bond strength of the cardboard. By testing the internal bonding strength of different processes and raw materials, manufacturers can determine the best production process and raw materials to produce better gray cardboard. In addition, the internal bonding strength Tester can also help manufacturers and users understand the internal bonding strength of gray cardboard under different humidity and temperature conditions, so as to determine its scope of application and service life.

During the test, similar to the test of electrical paperboard, electrical insulation paperboard, paper tube and yarn tube paper, and kraft paper, it is necessary to prepare test samples first, place them on the test bench, and start the test after adjusting the test parameters. After the test is completed, the internal bonding strength of the gray cardboard can be evaluated according to the test results, so as to improve the quality and reliability of the product.

Detection steps

Specifically, in the internal bonding force test of gray cardboard, the following steps can be followed:

1. Prepare the test sample: cut a sample of a certain size from the gray cardboard, generally rectangular or square, and the size and shape should meet the test requirements.

2. Install the test sample: place the test sample on the test table of the internal adhesion Tester, align and clamp it to ensure that the sample is fixed.

3. Adjust test parameters: According to the test requirements, adjust the test parameters of the internal binding force Tester, such as test speed, pressure range, etc.

4. Start the test: Start the internal binding force Tester and start the test. During the test, the instrument applies gradually increasing pressure until separation occurs between the different layers. During the test, the pressure value and test time can be recorded for subsequent analysis.

5. Analysis of the test results: After the test is completed, the internal bonding strength of the gray cardboard can be evaluated according to the test results. If the test results meet the requirements, the internal bonding strength of the gray cardboard can be guaranteed, thereby improving the quality and reliability of the product.

NBCHAO reminds you: when testing the internal bonding force of gray cardboard, it is necessary to pay attention to the size and shape of the test sample, as well as the selection of test parameters. Gray cardboard usually has high hardness and thickness, and the test parameters need to be adjusted properly to adapt to its special physical properties during testing. At the same time, the gray cardboard may be coated with a layer of paint or covered with a layer of plastic film, which may affect the test results and requires special attention.

In short, the internal bonding force Tester plays an important role in the manufacture and use of gray cardboard, which can help manufacturers and users understand the quality and reliability of gray cardboard, and improve the service life and safety of products. When testing, it is necessary to pay attention to the use of the instrument and the adjustment of the test parameters to ensure the accuracy and reliability of the test results.
