電泳線中的導(dǎo)電過程主要發(fā)生在工件（被涂裝的物體）與電泳槽中的電解液之間。電泳線是利用電場作用下帶電粒子在介質(zhì)中定向移動(dòng)的原理，進(jìn)行金屬表面處理和涂裝等操作的設(shè)備。以下是電泳線導(dǎo)電的具體分析：

　　The conductive process in the electrophoresis line mainly occurs between the workpiece (coated object) and the electrolyte in the electrophoresis tank. Electrophoretic line is a device that utilizes the principle of charged particles moving directionally in a medium under the action of an electric field to perform metal surface treatment and coating operations. The following is a specific analysis of the conductivity of electrophoresis lines:

　　一、電泳線的基本工作原理

　　1、 The basic working principle of electrophoresis line

　　電泳涂裝的基本原理可以概括為：在直流電場的作用下，帶正電荷或負(fù)電荷的膠體粒子（如涂料中的樹脂和顏料粒子）向相應(yīng)的電極（陰極或陽極）移動(dòng)，并沉積在基底表面形成涂膜。具體來說，若涂料粒子帶負(fù)電，工件作為陽極，則稱為陽極電泳；反之，若涂料粒子帶正電，工件作為陰極，則稱為陰極電泳。

　　The basic principle of electrophoretic coating can be summarized as follows: under the action of a direct current electric field, positively or negatively charged colloidal particles (such as resin and pigment particles in coatings) move towards the corresponding electrode (cathode or anode) and deposit on the substrate surface to form a coating film. Specifically, if the coating particles are negatively charged and the workpiece serves as the anode, it is called anodic electrophoresis; On the contrary, if the paint particles are positively charged and the workpiece acts as the cathode, it is called cathodic electrophoresis.

　　二、電泳線的導(dǎo)電過程

　　2、 The conductive process of electrophoresis lines

　　工件準(zhǔn)備：工件在進(jìn)入電泳槽之前，通常需要進(jìn)行預(yù)處理，如除油、除銹、磷化等，以提高涂膜的附著力。

　　Workpiece preparation: Before entering the electrophoresis tank, the workpiece usually needs to be pre treated, such as degreasing, rust removal, phosphating, etc., to improve the adhesion of the coating.

　　電泳槽與電解液：電泳槽中充滿了電解液，該電解液由涂料與蒸餾水按一定比例稀釋后形成。電解液中的涂料粒子帶有電荷，能夠在電場中定向移動(dòng)。

　　Electrophoresis tank and electrolyte: The electrophoresis tank is filled with electrolyte, which is formed by diluting paint and distilled water in a certain proportion. The coating particles in the electrolyte carry charges and can move directionally in an electric field.

　　電場建立：當(dāng)工件進(jìn)入電泳槽并浸沒在電解液中時(shí)，通過電泳供電系統(tǒng)對(duì)工件和電泳槽的電極進(jìn)行通電，從而在工件與電極之間建立電場。

　　Electric field establishment: When the workpiece enters the electrophoresis tank and is immersed in the electrolyte, the electrophoresis power supply system is used to energize the workpiece and the electrodes of the electrophoresis tank, thereby establishing an electric field between the workpiece and the electrodes.

　　帶電粒子移動(dòng)：在電場的作用下，帶電的涂料粒子開始定向移動(dòng)。對(duì)于陰極電泳，帶負(fù)電的涂料粒子向工件（陰極）移動(dòng)；對(duì)于陽極電泳，帶正電的涂料粒子向工件（陽極）移動(dòng)。

　　Charged particle movement: Under the action of an electric field, charged paint particles begin to move in a directional manner. For cathodic electrophoresis, negatively charged coating particles move towards the workpiece (cathode); For anodic electrophoresis, positively charged coating particles move towards the workpiece (anode).

　　涂料沉積：涂料粒子在電場力的作用下，不斷向工件表面沉積，逐漸形成均勻的涂膜。這個(gè)過程稱為電沉積。

　　Coating deposition: Coating particles continuously deposit onto the surface of the workpiece under the action of electric field force, gradually forming a uniform coating film. This process is called electrodeposition.

　　電滲作用：在電場作用下，涂膜內(nèi)部的水分從涂膜中滲析出來，移向槽液，使涂膜脫水，從而變得更加致密和耐腐蝕。

　　Electroosmosis: Under the action of an electric field, the water inside the coating is dialyzed out and moved towards the tank solution, causing the coating to dehydrate and become denser and more corrosion-resistant.

　　三、電泳線的導(dǎo)電特點(diǎn)

　　3、 The conductive characteristics of electrophoresis lines

　　電場方向可控：通過調(diào)整電泳供電系統(tǒng)的電壓和電流，可以控制電場的方向和強(qiáng)度，從而控制涂料粒子的移動(dòng)速度和路徑。

　　Controllable direction of electric field: By adjusting the voltage and current of the electrophoresis power supply system, the direction and intensity of the electric field can be controlled, thereby controlling the movement speed and path of the coating particles.

　　涂裝效率高：電泳涂裝能夠?qū)崿F(xiàn)自動(dòng)化生產(chǎn)，涂裝速度快，且涂膜均勻、附著力強(qiáng)。

　　High coating efficiency: Electrophoretic coating can achieve automated production, fast coating speed, uniform coating, and strong adhesion.

　　節(jié)能環(huán)保：電泳涂裝過程中，電解液可以循環(huán)利用，減少了水資源的浪費(fèi)。同時(shí)，電泳涂裝產(chǎn)生的廢水、廢氣等污染物較少，符合環(huán)保要求。

　　Energy saving and environmental protection: During the electrophoretic coating process, the electrolyte can be recycled, reducing the waste of water resources. At the same time, the wastewater, exhaust gas and other pollutants generated by electrophoretic coating are relatively small, which meets environmental protection requirements.

　　綜上所述，電泳線中的導(dǎo)電過程是通過電場作用使帶電涂料粒子定向移動(dòng)并沉積在工件表面形成涂膜的過程。這個(gè)過程需要電泳供電系統(tǒng)提供電場、電解液提供帶電粒子以及工件作為電極參與反應(yīng)。

　　In summary, the conductive process in electrophoresis lines is the process of directing charged coating particles to move and deposit on the surface of the workpiece to form a coating film through the action of an electric field. This process requires an electrophoresis power supply system to provide an electric field, an electrolyte to provide charged particles, and a workpiece as an electrode to participate in the reaction.
