Through the temperature resistance test, the temperature resistance performance of the film pressure workpiece can be inspected. The temperature resistance test must first collect the relevant parameters of the test piece, such as environmental parameters, process parameters, glue types (including activation temperature, factory date, number of glue spraying times), PVC parameters (thickness, adhesive, manufacturer, etc.), processing time, Chen Fang time and so on.

The temperature resistance test is carried out in a constant temperature box. The test temperatures are 40°C, 50°C, 60°C, 65°C, 70°C, 75°C, and 80°C. Put it at each temperature point from low to high for 1 hour, and then check whether the PVC on the surface and edge of the test piece is peeled or open. If the lower temperature does not peel or open, and when the temperature rises, the If the edge is opened, the temperature resistance of the test sample is one level lower. When a test piece is tested at 40℃ for 1 hour, the PVC does not peel off or the edges are open, and when the test is at 50℃ for 1 hour, the PVC is peeled or open.
