        6061鋁板表面電泳涂裝處理工藝

        來源:http://www.kongyh.com

        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。
        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鋁板和對應的電極放入水溶性涂料中,接上電源后,依靠電場所產生的物理化學作用,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雜的電化學反應過程,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:

        Electrophoretic coating is compared with other coating methods, with the following characteristics:
        (1)采用水溶性涂料,以水為溶解介質,節省了大量有機溶劑,大大降低了大氣污染和環境危害,安全衛生,同時避免了火災的隱患;
        (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)涂裝效率高,涂料損失小,涂料的利用率可達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)涂膜厚度均勻,附著力強,涂裝質量好,工件各個部位如內層、凹陷、焊縫等處都能獲得均勻、平滑的漆膜,解決了其他涂裝方法對復雜形狀工件的涂裝難題;
        (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)生產效率高,施工可實現自動化連續生產,大大提高勞動效率;
        (4) high production efficiency, the construction can achieve automatic continuous production, greatly improve the efficiency of labor;
        (5)設備復雜,投資費用高,耗電量大,其烘干固化要求的溫度較高,涂料、涂裝的管理復雜,施工條件嚴格,并需進行廢水處理;
        (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,在涂裝過程中不能改變顏色,涂料貯存過久穩定性不易控制。
        (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.
