Technical Field
[0001] The utility model relates to the field of hot pressing films, in particular to a spraying device for hot pressing films. Background Art
[0002] Hot pressing is a process used to process and decorate the surface of wood panels. It is commonly used for the surface treatment of wooden products such as furniture, flooring, doors, and windows. Specifically, hot pressing involves softening a thermoplastic film or paper by heating, then pressing it onto the surface of the wooden panel, creating an integrated decorative or protective layer. This process is primarily categorized into two types: Hot pressing plastic film: This involves softening a thermoplastic film by heating, pressing it onto the panel surface, and then solidifying it by cooling to form a decorative layer. Hot pressing paper: This involves heating and pressing decorative paper to activate its adhesive, adhering it to the panel surface to form a decorative or protective layer. Hot pressing technology can create a variety of decorative effects, such as simulated wood grain, stone grain, and leather grain, while also enhancing the panel's wear resistance and stain resistance. This process is widely used in furniture manufacturing, interior decoration, and architectural decoration, and is favored by the industry for its efficiency and aesthetic appeal.
