The problem that plastic products will fall off for a long time

First of all, this kind of product is not suitable for use in very hot places, because the high temperature will make the durability of the glue worse and it will be easy to fall off. However, technological innovation is relatively fast now. At present, choosing high-quality MDF boards and good glue will easily prevent the PVC film from falling off.

Because in addition to the factors such as high temperature and frequent fire baking, the quality of the raw materials is also a problem. Some boards are not dense enough, and the glue is absorbed after spraying glue, and some glue particles are too large, causing the surface to be uneven. , Easy to fall off.

Seven years ago, a negative pressure machine was generally used to stick the film. At present, it is a positive and negative pressure machine in China, which will make the glue reach the activation point, so that the PVC film and the surface of the door panel can be better attached.
