How does pvc wood grain blister film work?

With the continuous development of the economy, more and more industries are moving towards the society. Now there are many decoration industries in the market. In daily life, we all hope that the decoration of our home will be better. Pvc wood grain blister film can be obtained in life. is widely used, but do you know how it works? If you still don't understand, follow me to learn it. PVC film pressing technology is very important in the furniture industry, especially in the production of door panels and cabinets. The medium and high density substrates are processed into various linear shapes and then blistered with various matt high gloss, color and texture PVC films, making the products colorful and dazzling, creating a great choice for consumers. However, products manufactured using this technology. The pros and cons of its quality vary widely. The reasons for these differences are not only the factors of the base material and the decorative material Pvc wood grain blister film itself, but also the control of the process parameters during the processing is also very important. The following takes an imported positive and negative pressure vacuum suction machine as an example, and uses the two-component suction plastic imported from Germany to explain the whole process. The working principle of the positive and negative pressure vacuum suction machine is to use the plasticity of the PVC film to heat and pressurize the PVC film to coat the surface of the workpiece through the adjustment and control of the film pressure time, the temperature in the equipment cavity and the air pressure. Working process: The workpiece is placed on the workbench; the workbench enters directly under the heating plate; the heating plate and the workbench are closed; the air between the heating plate and the silica gel film is drawn out, and the silica gel film is adsorbed on the heating plate and heated; the setting is reached After a period of time, compressed air is injected between the heating plate and the silicone film, the silicone film is in close contact with the Pvc wood grain blister film, the workpiece and the Pvc wood grain blister film are heated, and the Pvc wood grain blister film is softened, and the edge of the board is softened. The temperature reaches the activation temperature of the glue; the air between the workbench and the Pvc wood grain blister film is quickly drawn out to form a vacuum, and then compressed air is injected between the Pvc wood grain blister film and the heating plate, and the PVC film is at the set pressure. It is coated on the plate under the action of temperature and temperature. The temperature resistance of the film-pressed workpiece can be checked through the temperature resistance test. The temperature resistance test must first collect the relevant parameters of the test piece, such as environmental parameters, process parameters, glue type (including activation temperature, date of manufacture, number of times of glue spraying), PVC film parameters (thickness, adhesive, manufacturer, etc.), processing time , Chen release time, etc. The temperature resistance test was carried out in an incubator, and the test temperatures were 40°C, 50°C, 60°C, 65°C, 70°C, 75°C, and 80°C, respectively. Put it at each temperature point from low to high for 1 hour, and then check whether the PVC film on the surface and edge of the test piece is peeled off or opened. If the edge is opened, the temperature resistance of the test sample is a lower temperature. When a test piece is tested at 40°C for 1 hour, the PVC is not peeled off or edged open, and when the PVC is tested for 1 hour at 50°C, the PVC is peeled off or edged, then the temperature resistance of the test sample is 40°C.
