Degumming detection method of silica gel protective film

The invention discloses a degumming detection method of a silica gel protective film. The degumming detection method comprises the following steps: (1) stripping a substrate of a silica gel protective film sample sheet and putting the sample sheet into a soaking solution; (2) after soaking for a period of time, taking out the sample sheet, and absorbing the soak solution; (3) fixing the soaked sample paper in the range of a friction head of a friction machine with the adhesive surface facing upwards; (4) a weight is inserted into a friction rod of the test bench support, the friction speed and the friction times are set, and friction processing is conducted on the sample; and (5) taking down the rubbed sample, checking under a fluorescent lamp, if degumming exists, judging that the sample is unqualified, otherwise, judging that the sample is qualified. According to the method, whether the silica gel surface of the silica gel protective film is degummed or not can be effectively determined, the product quality
