How to test the pressure resistance of self-adhesive coated paper?

The pressure resistance test of self-adhesive coated paper is a professional process designed to evaluate the paper's ability to resist deformation or cracking under a certain pressure. The following are the general steps and precautions for the pressure resistance test of self-adhesive coated paper:

First, test equipment

Static testing machine: used to test the pressure resistance of paper. The device is able to apply a constant pressure to a paper sample and measure its resistance to deformation.

Dynamic testing machine (if applicable) : Although it is mainly used to test the fatigue properties of paper, in some cases it can also be used to simulate dynamic pressure changes in actual use to evaluate the comprehensive compressive resistance of paper.

Second, test standards

Stress resistance tests should follow the relevant international or national standards, such as ISO, TAPPI or GB/T. These standards specify requirements for test methods, sample preparation, test conditions, and data processing.

Third, test steps

1. Sample preparation:

The self-adhesive coated paper sample is cut according to the size and shape specified in the standard.

Ensure that the surface of the sample is flat and free of wrinkles, and remove impurities that may affect the test results.

2. Conditioning:

The sample was placed under standard temperature and humidity conditions (such as temperature 23±1℃, relative humidity 50±5%) for balance treatment to eliminate the impact of environmental factors on the test results.

3. Installation sample:

Place the processed sample on the test platform and ensure that the sample is in close contact with the platform.

4. Set parameters:

Set test pressure, speed and other parameters according to test standards. The selection of these parameters should be able to truly reflect the stress of the paper in actual use.

5. Start the test:

Start the test equipment and apply pressure until the sample breaks or reaches a predetermined amount of deformation.

6. Record data:

Record the pressure changes during the test, the amount of deformation of the sample, and the maximum pressure at the time of rupture.

7. Data processing:

The compressive strength and other performance parameters of the paper were calculated according to the test standard. These parameters can be used to evaluate the compression resistance of the paper.

Fourth, precautions

1.Equipment verification: Ensure that the test equipment is verified and maintained in good condition to ensure the accuracy of the test results.

2.Sample consistency: All test samples should be prepared and processed under the same conditions to ensure comparability of test results.

3.Safe operation: Pay attention to safe operation during the test to avoid accidents.

4.Detailed recording: Test data should be recorded in detail and kept in good condition for subsequent analysis and comparison.

It should be noted that due to the special properties of self-adhesive coated paper (such as surface coating layer, adhesive layer, etc.), its pressure resistance test may need to consider additional factors, such as the impact of the adhesive layer on the test results. Therefore, before testing, you should carefully read and follow the relevant test standards or specifications.

In addition, the pressure resistance of self-adhesive coated paper of different brands, specifications and manufacturing processes may be different. Therefore, in the specific application, the appropriate self-adhesive coated paper should be selected according to the actual needs, and the necessary tests should be carried out to evaluate its performance.
