1. Prepare raw materials
The main raw materials of laminated boards are substrates, films, and glues. Substrates are often used in MDF, particleboard, MDF, etc., among which MDF is the most commonly used. There are many types of films, such as PVC, hot-pressed film, acrylic film, etc. When choosing a film, you should choose it according to the desired application, color, and texture. In terms of film gluing, commonly used glues are PU, EVA, etc.
Second, the film
Lamination is an important step in the laminating process. First of all, you need to prepare the work surface and manual hot plate. Place the substrate on the work surface, attach the film flat to the substrate, and use a scraper to squeeze out the air bubbles. Then use a manual hot plate to heat the film until the glue melts, and then use the scraper to continue flattening to allow the film to fit the substrate completely.
3. Pressurization
After the film is completed, the substrate needs to be pressurized and cured to ensure the firmness of the film. When pressurizing, it is necessary to pay attention to the control of temperature and time, and the method of temperature control at 80-100 °C for 10-15 minutes is generally adopted. In the pressurization process, the appropriate pressing method and pressing pressure should also be selected according to the material and requirements of the substrate.
Fourth, curing
After the pressurization is completed, the laminated board needs to be cured to ensure the hardness and moisture resistance of the board. Curing is often done by spraying, where the surface of the board is evenly sprayed with a curing agent, and then the plate is placed in a high-temperature oven for curing. The curing time and temperature should be adjusted according to the material of the different hardeners and substrates.
The above is the main process flow of laminated board formation. Through these steps, it is possible to produce a laminated board material with stable quality and good aesthetics. In practice, it is also necessary to pay attention to the operational details and environmental requirements of each step to ensure the stability and reliability of the production process and the quality of the finished product.
