6061铝板表面处理方式电泳涂装是利用外加电场使悬浮于电泳液中的颜料和树脂等微粒定向迁移并沉积于电极之一的基底表面的涂装方法。电泳涂装具有水溶性、无毒、易于自动化控制等特点。
6061, the surface treatment of aluminum plate is electrophoretic coating, which uses the external electric field to transfer and deposit particles such as pigment and resin in the electrophoretic liquid, and deposit on the substrate surface of the electrode. The electrophoretic coating is water-soluble, nontoxic, and easy to automate control and so on.
电泳涂装是把6061铝板和对应的电极放入水溶性涂料中,接上电源后,依靠电场所产生的物理化学作用,使涂料中的树脂、颜填料在以6061铝板为电极的表面上均匀析出沉积形成不溶于水的漆膜的一种涂装方法。
Electrophoretic coating the electrodes are 6061 aluminum plate and the corresponding into water soluble coating, when the power is connected, depending on the physical and chemical effects produced by the electric field, the resin, pigments and fillers in coating a coating method on the surface of the electrode uniform deposition to form insoluble film on 6061 aluminum.
电泳涂装是一个极为复杂的电化学反应过程,其中至少包括电泳、电沉积、电渗、电解四个过程。电泳涂装按沉积性能可分为阳极电泳(工件是阳极,涂料是阴离子型)和阴极电泳(工件是阴极,涂料是阳离子型);按电源可分为直流电泳和交流电泳;按工艺方法又有定电压和定电流法。目前在工业上较为广泛采用的是直流电源定电压法的阳极电泳。
Electrophoretic coating is a very complex electrochemical reaction process, which includes at least four processes: electrophoretic, electrodeposition, electroosmosis and electrolysis. Electrophoretic coating can be divided into anodic electrophoretic (workpiece anode, paint anionic) and cathodic electrophoretic (workpiece is cathode, coating is cationic), according to the power supply, it can be divided into DC electrophoresis and AC electrophoresis, according to the process, there are fixed voltage and fixed current method. At present, the anode electrophoretic method of DC power supply is widely used in the industry.
电泳涂装与其他涂装方法相比较,具有下述特点:
