Electrophoretic paint is a type of coating product that can be applied to the coating of hardware components such as electromechanical, household appliances, and automobiles. Especially when used in the coating film, it can play a protective and anti-corrosion role. Below is an introduction to the precautions for pre-treatment electrophoresis process?

与一般溶剂型涂料和粉末涂料的前处理电泳相比本质上是相同的，但基于电泳涂装是一种特殊的水性涂料，其涂装工艺是多种类型的组合.的物理和电化学反应。因此，可以看出其产品表面处理的好坏，直接影响电泳涂装后电泳漆膜的质量和工件的使用寿命，因此应予以高度重视。

Compared with the pre-treatment electrophoresis of general solvent based coatings and powder coatings, electrophoretic coating is essentially the same, but based on electrophoretic coating, it is a special water-based coating, and its coating process is a combination of various types of physical and electrochemical reactions. Therefore, it can be seen that the quality of the surface treatment of its products directly affects the quality of the electrophoretic coating film and the service life of the workpiece after electrophoretic coating, so it should be highly valued.

特别是其涂装前的磷化膜符合相关质量标准。前处理电泳还有一点很重要，它的处理膜薄、均匀、致密，无磷化残留物或铁粉粘附，无点痕迹。为保证被涂物表面电导率的均匀性，磷化膜不能太厚，通常为薄膜磷化。特别是本产品，在涂装过程中被涂物表面会产生强烈的电化学反应（如阴极电泳时涂装界面呈强碱性等），前处理电泳得到的转化膜应具有很强的耐化学性。也就是说，既要注意前处理转化膜与电泳漆的相容性，也要注意转化膜的成分。

Especially, the phosphating film before coating meets relevant quality standards. Another important aspect of pre-treatment electrophoresis is that its treatment film is thin, uniform, dense, without phosphate residue or iron powder adhesion, and without any trace. To ensure the uniformity of the surface conductivity of the coating, the phosphating film should not be too thick, usually thin film phosphating. Especially for this product, during the coating process, there will be strong electrochemical reactions on the surface of the coating material (such as strong alkaline coating interface during cathodic electrophoresis), and the conversion film obtained by pre-treatment electrophoresis should have strong chemical resistance. That is to say, attention should be paid to the compatibility between the pre-treatment conversion film and the electrophoretic paint, as well as to the composition of the conversion film.

前处理电泳应清洗得更干净，避免将杂质离子和污物引入待涂物。电泳槽的油漆质量，会影响槽液的稳定性和稳定性。或者可以不让油渍、水溶性盐类、不良导体附着在被涂物上；前处理用纯水后洗涤后的滴水电导率应小于30um/cm。另外，对耐腐蚀性要求高的产品应采用锌基磷化，甚至三重锌基磷化。锌基磷化需要表面凝固，用钛盐或其他物质对工件表面进行活化，此时其主要作用是增加磷化膜晶体的成核点，增加晶体密度，降低。粒度和重量，并改善磷酸盐膜结构。前处理电泳良好的表面调质处理是形成良好磷化膜的重要保证。正常的磷化膜应该是均匀、完整、致密的，前处理电泳要求是保证电泳前没有黄锈！产品磷化后，电泳前还应进行清洗，用去离子水清洗。

The pre-treatment electrophoresis should be cleaned cleaner to avoid introducing impurities, ions, and dirt into the coating material. The paint quality of the electrophoresis tank will affect the stability and stability of the tank solution. Alternatively, it is possible to prevent oil stains, water-soluble salts, or defective conductors from adhering to the coated material; The conductivity of the dripping water after washing with pure water for pre-treatment should be less than 30um/cm. In addition, products with high requirements for corrosion resistance should use zinc based phosphating, or even triple zinc based phosphating. Zinc based phosphating requires surface solidification, and titanium salts or other substances are used to activate the surface of the workpiece. At this time, its main function is to increase the nucleation point of the phosphating film crystal, increase the crystal density, and reduce it. Particle size and weight, and improve the structure of phosphate film. A good surface conditioning treatment for pre-treatment electrophoresis is an important guarantee for the formation of a good phosphating film. The normal phosphating film should be uniform, complete, and dense, and the requirement for pre-treatment electrophoresis is to ensure that there is no yellow rust before electrophoresis! After phosphating, the product should also be cleaned with deionized water before electrophoresis.
