Description

Technical Field

[0002] Skin-feel decorative panels refer to decorative panels with special effects in appearance and touch, and are usually used for the decoration of walls, ceilings, furniture, etc. inside and outside buildings. It combines beauty, practicality and a unique tactile experience, giving people a more textured touch feeling. Skin-feel decorative panels are usually manufactured using high-tech materials and processes. For example, films, coatings, composite materials, etc. with special textures are used, and the surface may undergo special processing, such as hot pressing, spraying, covering and other technologies, to achieve better tactile effects. Electrostatic spraying is a technology that uses the effect of electric charge to achieve uniform adhesion of paint to the surface of the workpiece. During the spraying process, the paint particles are electrostatically charged and then sprayed onto the surface of the object to be coated through a spray gun. The object itself usually has an opposite charge to the sprayed particles, so that the paint can be firmly adsorbed on the surface. Electrostatic spraying technology can improve the surface quality and durability of decorative panels, while providing unique visual and tactile effects. The existing electrostatic powder spraying equipment for skin-feel decorative panels generates a large amount of dust during the spraying process, which deteriorates the working environment, affects the health of operators and pollutes the environment.
