I. Introduction. The tape annular tack tester is a device used to measure the initial adhesion of adhesive tape. It evaluates the adhesive properties of adhesive tapes by simulating the process of attaching and separating them in real-world applications. This article will introduce in detail the test principle, operation method and precautions of the tape annular initial tack tester.
Second, the test principle.
The test principle of the tape ring tack tester is based on the following steps: First, the annular specimen is in full contact with a standard float glass test plate at a constant speed of 300 mm min. In this process, the contact area between the tape specimen and the breadboard gradually increases until it is fully conformed. The tester then automatically reverses to completely separate the annular specimen from the breadboard at a constant speed of 300 mm min. In this process, the adhesion between the specimen and the breadboard will cause the specimen to produce a reverse force. The magnitude of this force is the annular initial tack of the test specimen.
3. How to operate.
Preparation: Make sure that the tape ring initial tack tester is in good working condition, and check whether the power supply, sensor, etc. are normal. At the same time, prepare enough annular specimens and standard float glass test plates.
Mounting the specimen: The annular specimen is installed in the fixture of the tester to ensure that the specimen is flat and free of bubbles.
Set parameters: According to the test requirements, set the test speed to 300mm min, and set the appropriate test time.
Start the test: Place the standard float glass breadplate on the tester's bench and start the tester. Observe the contact and separation of the specimen and the test board during the test, and record the test data.
Data analysis: According to the test data, analyze the annular initial adhesion of the specimen and evaluate its adhesion performance.
4. Precautions.
Before performing the test, make sure that the annular specimen and standard float glass breadplate are clean and dry, free of oil or dust.
During the test, pay attention to the contact between the specimen and the test plate to ensure that the contact is uniform and free of bubbles.
Perform regular maintenance on the tester to ensure that it is working properly.
When analyzing data, appropriate statistical methods should be used to process and analyze the data to draw accurate conclusions.
V. Conclusions. The tape annular initial adhesion tester is an effective device for measuring the initial adhesion of adhesive tape. By understanding the testing principle and mastering the correct operation method, the adhesion performance of the tape can be accurately evaluated, and the quality control and research and development of the product can be strongly supported. In practical applications, care should be taken to comply with operating procedures and precautions to ensure the accuracy and reliability of test results.
