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:

Electrophoretic coating is compared with other coating methods, with the following characteristics:
(1)采用水溶性涂料,以水为溶解介质,节省了大量有机溶剂,大大降低了大气污染和环境危害,安全卫生,同时避免了火灾的隐患;
(1) using water-soluble coatings and water as the dissolution medium saves a lot of organic solvents, greatly reducing air pollution and environmental hazards, safety and hygiene, and avoiding hidden dangers of fire.
(2)涂装效率高,涂料损失小,涂料的利用率可达90%~95%;
(2) the efficiency of coating is high, the loss of coating is small and the utilization rate of the coating can reach 90% ~ 95%.
(3)涂膜厚度均匀,附着力强,涂装质量好,工件各个部位如内层、凹陷、焊缝等处都能获得均匀、平滑的漆膜,解决了其他涂装方法对复杂形状工件的涂装难题;
(3) the coating thickness is uniform, the adhesion force is strong, and the coating quality is good. All parts of the workpiece, such as inner layer, sag and weld seam, can get uniform and smooth paint film, which solves the problem of other painting methods for coating complex shaped workpieces.
(4)生产效率高,施工可实现自动化连续生产,大大提高劳动效率;
(4) high production efficiency, the construction can achieve automatic continuous production, greatly improve the efficiency of labor;
(5)设备复杂,投资费用高,耗电量大,其烘干固化要求的温度较高,涂料、涂装的管理复杂,施工条件严格,并需进行废水处理;
(5) the equipment is complex, the investment cost is high, the power consumption is large, the temperature required for drying and curing is higher, the management of coating and coating is complex, the construction conditions are strict, and the wastewater treatment is needed.
(6)只能采用水溶性涂料,在涂装过程中不能改变颜色,涂料贮存过久稳定性不易控制。
(6) only water soluble coatings can be used, and the color can not be changed during the coating process. The stability of the coating is not easy to be controlled for long storage.
