In today's industrial production, the application of cardboard is becoming more and more extensive, and the friction properties of cardboard have an important impact on its use effect and safety. In order to accurately evaluate the friction properties of cardboard, the cardboard friction performance tester came into being. This article will analyze the test principle and operation method of the cardboard friction performance tester in detail.
First, the test principle.
The test principle of the cardboard tribology tester is based on the measurement of frictional force. During the test, one of the two materials involved in the coefficient of friction test is laid flat on the test table and the other is fixed on a slider of a certain weight. When two test surfaces move relative to each other under a certain contact pressure, friction is formed. The coefficient of friction value is obtained by recording the required friction force and dividing the measured force by the gravity of the slide.
Second, the test operation method.
Prepare the material: Select the cardboard sample to be tested and lay it flat on the test table. At the same time, prepare a slider of a certain weight to ensure that the slider surface is in good contact with the cardboard surface.
Install the slider: Fix the slider in the corresponding position of the tester to ensure that the slider can move stably during the test.
Set parameters: Set the contact pressure, slider weight, moving speed and other parameters according to the test requirements.
Start Test: Start the tester so that the slider moves relative to the surface of the cardboard under the set parameters. During this process, the tester automatically records friction data.
Calculation of friction coefficient: The friction coefficient value is calculated according to the friction force obtained from the test and the weight of the slider. The specific calculation formula is: coefficient of friction = friction measured by the test and weight of the slide.
Analysis results: The friction properties of the cardboard are evaluated based on the value of the coefficient of friction. In general, the higher the coefficient of friction, the better the slip resistance of the cardboard.
Through the above steps, we can use the cardboard friction property tester to accurately evaluate the friction properties of the cardboard. This test result has important reference value for the use effect and safety of cardboard in various application scenarios. At the same time, it also provides reliable testing tools for related companies and researchers, which helps to promote the sustainable development of the paperboard industry.
