1. Fluorine release membrane instrument and test materials: tensile machine, four-dimensional MY2G test tape;
2. Scope of application: release force test of fluorine release membrane;
3. Operation steps:
(1) Take 25.4mm wide and 200mm long four-dimensional MY2G tape and stick it to the test surface (release surface) of the film, and use 2KG standard roller to repeatedly roll it for three times. (Note: the adhesive tape shall be pressed at the same time to avoid bubbles between the adhesive tape and the release film;)
(2) After sticking the tape, let it stand for 30 minutes, and control the temperature and humidity of the laboratory at 25 ± 3 ℃ and 50 ± 10% respectively;
(3) Apply double-sided adhesive tape to the non test surface of the sample and fix it on the standard steel plate for testing.
(4) Install the material onto the fixture, and use a tensile machine to stretch the test tape at an angle of 180 degrees and a speed of 300 mm/MIN. The data displayed on the computer of the tensile machine is the release force (g/in) of the test piece. Take the average value of five values as the test result.
