Film Pressure Workpiece Temperature Test
Feb 05, 2018

Through the temperature test can test the pressure-resistant parts of the temperature performance. Temperature resistance test should first collect the relevant parameters of the specimen, such as environmental parameters, process parameters, plastic species (including the activation temperature, the date of manufacture, the number of times of spraying), PVC parameters (thickness, Chen Fang time and so on.

In the incubator temperature test, the test temperature was 40 ℃, 50 ℃, 60 ℃, 65 ℃, 70 ℃, 75 ℃, 80 ℃. From low to high at each temperature for 1 hour, and then check whether the surface of the specimen and the edge of the PVC stripped or open the edge, if the lower temperature does not occur peeling or open edge, and when the temperature rise of a peel or Open the edge, then the temperature of the test sample is a lower temperature. A test piece at 40 ℃ for 1 hour PVC did not peel or open the edge of the test at 50 ℃ for 1 hour PVC stripped or open side, then the temperature of the test sample is 40 ℃.
