6061鋁板表面處理方式電泳涂裝是利用外加電場使懸浮于電泳液中的顏料和樹脂等微粒定向遷移并沉積于電極之一的基底表面的涂裝方法。電泳涂裝具有水溶性、無毒、易于自動化控制等特點(diǎn)。
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.
電泳涂裝是把6061鋁板和對應(yīng)的電極放入水溶性涂料中,接上電源后,依靠電場所產(chǎn)生的物理化學(xué)作用,使涂料中的樹脂、顏填料在以6061鋁板為電極的表面上均勻析出沉積形成不溶于水的漆膜的一種涂裝方法。
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.
電泳涂裝是一個極為復(fù)雜的電化學(xué)反應(yīng)過程,其中至少包括電泳、電沉積、電滲、電解四個過程。電泳涂裝按沉積性能可分為陽極電泳(工件是陽極,涂料是陰離子型)和陰極電泳(工件是陰極,涂料是陽離子型);按電源可分為直流電泳和交流電泳;按工藝方法又有定電壓和定電流法。目前在工業(yè)上較為廣泛采用的是直流電源定電壓法的陽極電泳。
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.
電泳涂裝與其他涂裝方法相比較,具有下述特點(diǎn):
Electrophoretic coating is compared with other coating methods, with the following characteristics:
