Interlayer internal bonding strength tester (hereinafter referred to as internal bonding strength tester) is a kind of instrument used to test the internal bonding strength of cardboard or paper. It can test the internal bond strength between different layers, as well as the bond strength within each layer. In the field of carton and paperboard manufacturing, the internal bonding force tester is a very important test equipment.

In the application of electrical cardboard, the internal bonding force tester can be used to test the bonding strength between different layers, as well as the overall bonding strength of the cardboard. Electrical cardboard is usually composed of multiple layers of cardboard and special insulating materials. The internal bonding force tester can help manufacturers and users understand the bonding strength of electrical cardboard, so as to determine its service life and quality.

How to use the interlayer bonding strength tester for electrical cardboard?

The testing principle of the internal bonding force tester is to measure the bonding strength between different layers by applying pressure, and the test results are usually expressed in terms of strength per unit area. For testing, the electrical cardboard sample is placed on the test bench and then gradually increasing pressure is applied until separation occurs between the different layers. Through the test results, manufacturers and users can determine whether the internal bonding strength of the electrical cardboard meets the requirements, as well as its reliability and durability.

In addition, the internal bonding force tester can also help electrical board manufacturers to determine better production processes and raw material selection to improve the quality and production efficiency of electrical board. By testing the internal bonding strength of different processes and raw materials, manufacturers can determine better production processes and raw materials, so as to produce better electrical cardboard.

In the electrical industry, electrical cardboard is an important insulating material, which is widely used in electrical equipment and power system. It has excellent insulation performance and arc resistance, which can protect power equipment from arc and short circuit damage. Therefore, the quality and performance of electrical board are of great importance to the safety and reliability of power system.

Method of test
The following are the test steps of the internal bonding force tester:

Prepare test samples: Cut samples of a certain size from the electrical cardboard, generally rectangular or square, the size and shape should meet the test requirements.

Install the test sample: Place the test sample on the test bench of the internal bonding force tester, align and clamp it to ensure that the sample is fixed.

Adjust the test parameters: according to the test requirements, adjust the test parameters of the internal bonding force tester, such as test speed, pressure range, etc.

Start the test: start the internal bonding force tester and start the test. When tested, the instrument will apply 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.

Analyze the test results: After the test is completed, the internal bond strength of the electrical cardboard can be evaluated according to the test results. If the test results meet the requirements, the internal bonding strength of the electrical board can be guaranteed, so as to improve the quality and reliability of the product.

In short, the internal bonding force tester is a very important test equipment, which can help electrical cardboard manufacturers and users understand the quality and reliability of electrical cardboard, so as to improve the service life and safety of electrical cardboard. When conducting the test, it is necessary to pay attention to the use method of the instrument and the adjustment of the test parameters to ensure the accuracy and reliability of the test results.
