　　Electrophoretic coating, as an efficient and environmentally friendly coating technology, has been widely used in modern industry. This article will provide a detailed introduction to the types of workpieces suitable for electrophoresis lines and their process flow, helping readers better understand this technology.

　　一、电泳线适用的工件

　　1、 Workpieces suitable for electrophoresis lines

　　电泳线适用于多种材质的工件，特别是那些对防腐性、装饰性和均匀性要求较高的产品。以下是一些典型的适用工件类型：

　　Electrophoretic lines are suitable for workpieces made of various materials, especially for products that require high anti-corrosion, decorative, and uniformity requirements. Here are some typical types of applicable workpieces:

　　1.金属工件：如汽车车身、汽车零部件（如轮毂、发动机部件）、家电外壳（如冰箱、洗衣机）、建筑五金（如门窗、栏杆）等。金属工件因其导电性好，非常适合电泳涂装。

　　1. Metal workpieces: such as car bodies, car parts (such as wheels, engine components), home appliance casings (such as refrigerators, washing machines), building hardware (such as doors, windows, railings), etc. Metal workpieces are very suitable for electrophoretic coating due to their good conductivity.

　　2.塑料制品：经过特殊处理的导电塑料也适用于电泳涂装。这类涂料能够赋予塑料表面金属质感，同时提高其耐磨、耐腐蚀性能。

　　2. Plastic products: Specially treated conductive plastics are also suitable for electrophoretic coating. This type of coating can give plastic surfaces a metallic texture while improving their wear and corrosion resistance.

　　3.玻璃及陶瓷制品：虽然这些材料本身不导电，但可以通过在表面涂覆导电层后进行电泳涂装，以达到装饰和防护的目的。

　　3. Glass and ceramic products: Although these materials themselves are non-conductive, they can be decorated and protected by electrophoretic coating after coating a conductive layer on the surface.

　　4.其他导电基材：如导电纤维、导电薄膜等，在特定应用场合下也需进行电泳涂装处理。

　　4. Other conductive substrates, such as conductive fibers, conductive films, etc., also require electrophoretic coating treatment in specific application scenarios.

　　二、电泳涂装工艺流程

　　2、 Electrophoretic coating process flow

　　1.预处理：

　　1. Preprocessing:

　　（1）预清理：清除工件表面的大颗粒杂质和油污。

　　(1) Pre cleaning: Remove large particle impurities and oil stains from the surface of the workpiece.

　　（2）除油：通过化学或物理方法去除工件表面的油脂和污垢，确保表面清洁。

　　(2) Oil removal: Remove grease and dirt from the surface of the workpiece through chemical or physical methods to ensure surface cleanliness.

　　（3）除锈：针对金属工件，采用喷砂、酸洗等方法去除表面锈蚀，提高附着力。

　　(3) Rust removal: For metal workpieces, methods such as sandblasting and acid washing are used to remove surface rust and improve adhesion.

　　（4）磷化：在工件表面形成一层磷化膜，提高涂层的附着力和耐腐蚀性能。

　　(4) Phosphating: Form a layer of phosphating film on the surface of the workpiece to improve the adhesion and corrosion resistance of the coating.

　　（5）水洗：多次水洗以去除前处理过程中残留的化学物质，保证表面清洁。

　　(5) Water washing: Multiple water washes to remove residual chemicals from the pre-treatment process and ensure surface cleanliness.

　　2.电泳涂装：

　　2. Electrophoretic coating:

　　（1）将预处理后的工件浸入电泳槽中，作为阳极（阳极电泳）或阴极（阴极电泳）。

　　(1) Immerse the preprocessed workpiece into an electrophoresis tank as an anode (anodic electrophoresis) or cathode (cathodic electrophoresis).

　　（2）在电泳槽中，涂料（电泳漆）与水按一定比例稀释后，形成带电胶体粒子。

　　(2) In the electrophoresis tank, the coating (electrophoretic paint) is diluted with water in a certain proportion to form charged colloidal particles.

　　（3）在直流电场的作用下，带电胶体粒子向工件表面移动并沉积，形成均匀的涂层。

　　(3) Under the action of a direct current electric field, charged colloidal particles move and deposit onto the surface of the workpiece, forming a uniform coating.

　　3.电泳后清洗：

　　3. Cleaning after electrophoresis:

　　（1）取出工件后，用超滤液和去离子水进行多次清洗，以去除表面残留的涂料和其他杂质。

　　(1) After removing the workpiece, clean it multiple times with ultrafiltrate and deionized water to remove residual coating and other impurities on the surface.

　　（2）清洗过程中注意避免涂层被破坏或产生二次流痕等弊病。

　　(2) During the cleaning process, be careful to avoid coating damage or secondary flow marks.

　　4.烘干成膜：

　　4. Drying to form a film:

　　（1）将清洗后的工件送入烘炉中，在规定的温度和时间下烘干，使涂层完全固化。

　　(1) Send the cleaned workpiece into an oven and dry it at the specified temperature and time to fully cure the coating.

　　（2）烘干过程中需注意温度均匀性，以保证涂层质量。

　　(2) During the drying process, attention should be paid to temperature uniformity to ensure the quality of the coating.

　　5.冷却与后处理：

　　5. Cooling and post-processing:

　　（1）烘干后的工件进行自然冷却或强制冷却。

　　(1) The dried workpiece is subjected to natural cooling or forced cooling.

　　（2）根据需要，进行后续的面漆涂装或其他表面处理工序。

　　(2) Perform subsequent topcoat coating or other surface treatment processes as needed.

　　6.特殊工艺与注意事项

　　6. Special processes and precautions

　　（1）多孔和缝隙零件：对于这类零件，可在脱脂后增加中途吹水工序，以防缝隙或孔中的水影响后续工序质量。

　　(1) Porous and crevice parts: For these types of parts, an intermediate water blowing process can be added after degreasing to prevent water in the crevices or holes from affecting the quality of subsequent processes.

　　（2）特殊材料：如高孔隙的粘接钕铁硼磁体，可能需要增加有机封孔工序以提高涂层质量。

　　(2) Special materials, such as high porosity bonded neodymium iron boron magnets, may require additional organic sealing processes to improve coating quality.

　　环保与安全：电泳涂装过程中会产生废液和废气等污染物，需配置相应的三废处理装置以确保环保达标。同时，操作人员需穿戴必要的防护装备以确保安全。

　　Environmental Protection and Safety: During the electrophoretic coating process, pollutants such as waste liquid and exhaust gas are generated, and corresponding three waste treatment devices need to be configured to ensure environmental compliance. At the same time, operators need to wear necessary protective equipment to ensure safety.

　　电泳线适用于多种材质的工件，其工艺流程包括预处理、电泳涂装、电泳后清洗、烘干成膜及冷却与后处理等主要步骤。通过合理的工艺设计和严格的操作控制，可以确保获得高质量的电泳涂层产品。

　　The electrophoresis line is suitable for workpieces made of various materials, and its process includes main steps such as pretreatment, electrophoresis coating, post electrophoresis cleaning, drying to form a film, and cooling and post-treatment. Through reasonable process design and strict operational control, high-quality electrophoretic coating products can be ensured.
