Description
技术领域technical field
本实用新型涉及涂布技术领域，具体为一种静电涂布装置。The utility model relates to the technical field of coating, in particular to an electrostatic coating device.
背景技术Background technique
静电喷涂技术广泛用于金属、汽车、家用电器、五金工具，静电喷涂是近几年来用于金属防腐、装饰性喷涂的一种替代液体涂料的喷涂新工艺，静电喷涂工艺是利用高压静电电场使带负电的涂料微粒沿着电场相反的方向定向运动，并将涂料微粒吸附在工件表面的一种喷涂方法，静电喷涂是无溶剂喷涂，彻底清除了传统涂刷技术所带来的环境污染，静电喷涂具有涂层附着力高，耐腐蚀性强，同时喷涂成本和喷涂工作效率大大提高，但是静电喷涂需要喷枪，当基材幅面超过喷枪有效喷涂直径时，就需要采用扫描方式进行喷涂，这样在两次扫描喷涂的连接处就会形成重叠，导致涂层厚度出现差异，影响成品质量。Electrostatic spraying technology is widely used in metals, automobiles, household appliances, and hardware tools. Electrostatic spraying is a new spraying process that replaces liquid coatings for metal anticorrosion and decorative spraying in recent years. Negatively charged paint particles move directionally in the opposite direction of the electric field and adsorb the paint particles on the surface of the workpiece. Electrostatic spraying is solvent-free spraying, which completely eliminates the environmental pollution caused by traditional painting techniques. Spraying has high coating adhesion and strong corrosion resistance. At the same time, the cost of spraying and the efficiency of spraying are greatly improved. However, electrostatic spraying requires a spray gun. When the substrate width exceeds the effective spraying diameter of the spray gun, it needs to be sprayed by scanning. The joints of the two scans will overlap, resulting in differences in coating thickness and affecting the quality of the finished product.
