Description
Technical Field
The invention relates to the technical field of release film physical analysis, in particular to release film stripping force detection equipment.
Background
The release film is widely applied to a plurality of fields such as electronics, medical treatment, aerospace and the like and is important for ensuring the quality of products. Among them, the 90-degree peel test of the release film is a key method for evaluating the peel performance thereof. In this test, the sample is firmly fixed to a specific test device (single column tensile tester), and then a force is applied in the vertical direction. By accurately measuring the applied force and the peel speed of the material, we can obtain important information about the adhesion strength.
The test process comprises the first step of preparing a release film sample and a steel plate, ensuring that the surface of the steel plate is smooth and clean and free of impurities, the second step of attaching the release film, namely uniformly adhering the release film to the surface of the steel plate by using rollers, ensuring that the attachment is tight and free of bubbles or wrinkles, the third step of adhering and stabilizing, namely standing for a period of time to ensure that the release film and the steel plate are adhered fully and stabilized, the fourth step of preparing a test sample, namely, installing a 90-degree stripping clamp on a single-column tensile testing machine, placing the release film sample fixed on the steel plate on a clamping device under the clamp, ensuring that the sample is aligned with the clamp, the fifth step of fixing the sample, namely, fixing the other end of the sample by using the upper clamp, ensuring firm fixation, the sixth step of setting test conditions, namely, setting the test type to be stripping, setting the test temperature to be room temperature, setting the test speed to be 50mm/min, and starting the test, starting the single-column tensile testing machine, recording tensile data in the test in real time, observing the stripping condition between the release film and the steel plate, stopping the test, after the test is completed, stopping the test, and analyzing the state data of the test, if necessary, and analyzing the state data of the test is further carried out, if necessary;
When the worker adheres the release film to the surface of the steel plate, the worker cannot basically ensure that the release film is just parallel to the length direction of the steel plate, and the upper clamp clamps the bottom end of the release film to vertically and upwards peel off the release film, as shown in fig. 2, the length of the horizontal line formed by peeling the release film on the steel plate is larger than the horizontal line formed by theoretically peeling the release film parallel to the length direction of the steel plate, namely the width of the release film, so that detection errors are caused, and the errors increase along with the increase of the skew degree of the release film attached by the worker.
The above information disclosed in the background section is only for enhancement of understanding of the background of the disclosure and therefore it may include information that does not form the prior art that is already known to a person of ordinary skill in the art.
