電泳線的技術(shù)演進(jìn)，正經(jīng)歷著從“溶劑型”到“水性化”的深刻變革。2025年，中國(guó)電泳涂裝行業(yè)進(jìn)入轉(zhuǎn)型階段，粉末電泳漆和水性電泳漆加速替代傳統(tǒng)溶劑型產(chǎn)品。這一轉(zhuǎn)變不僅是環(huán)保要求的驅(qū)動(dòng)，更是涂裝質(zhì)量提升的內(nèi)在需求。

The technological evolution of electrophoresis lines is undergoing a profound transformation from "solvent based" to "water-based". In 2025, China's electrophoretic coating industry will enter a transformation stage, with powder electrophoretic paint and water-based electrophoretic paint accelerating the replacement of traditional solvent based products. This transformation is not only driven by environmental requirements, but also an inherent demand for improving coating quality.

在技術(shù)革新層面，電泳線的核心工藝正在不斷優(yōu)化。逆流循環(huán)工藝是近年來電泳線的重要技術(shù)突破——電泳槽非采用普通的順流工藝，而是選擇逆流工藝，在運(yùn)行成本及車身質(zhì)量方面具有顯著優(yōu)勢(shì)。調(diào)試過程中需關(guān)注槽液流動(dòng)方向、表面流速、層流噴嘴噴射角度等工藝參數(shù)。電泳線體輸送方式也日趨多樣化，主要分為雙擺桿、C型鉤、自行小車、360°翻轉(zhuǎn)機(jī)等。自行小車+葫蘆+吊具輸送形式在汽車涂裝中得到廣泛應(yīng)用。

At the level of technological innovation, the core process of electrophoresis lines is constantly being optimized. The counter current circulation process is an important technological breakthrough in recent years for electrophoresis lines - the electrophoresis tank does not use the ordinary co current process, but chooses the counter current process, which has significant advantages in operating costs and vehicle quality. During the debugging process, attention should be paid to process parameters such as the flow direction of the tank liquid, surface flow velocity, and the spray angle of the laminar flow nozzle. The transportation methods of electrophoresis lines are becoming increasingly diversified, mainly divided into double pendulum rods, C-hooks, self-propelled carts, 360 ° flip machines, etc. The transportation form of self-propelled carts, hoists, and lifting equipment has been widely used in automotive painting.

在產(chǎn)線升級(jí)方面，企業(yè)正通過技術(shù)改造提升電泳線的效率和品質(zhì)。電泳漆膜是涂裝防腐最重要的保障，因產(chǎn)線生產(chǎn)節(jié)拍、產(chǎn)線投入、場(chǎng)地面積等影響，電泳線體配置需要個(gè)性化定制。智能化電泳和噴漆涂裝生產(chǎn)線的引入，使板簧產(chǎn)品的表面涂覆率和漆膜質(zhì)量顯著提升，防腐蝕性能增強(qiáng)。針對(duì)零部件復(fù)雜結(jié)構(gòu)的涂裝死角問題，量身打造專屬電泳涂裝生產(chǎn)線已成為行業(yè)趨勢(shì)。

In terms of production line upgrading, enterprises are improving the efficiency and quality of electrophoresis lines through technological transformation. Electrophoretic paint film is the most important guarantee for coating and anti-corrosion. Due to factors such as production pace, production line investment, and site area, the configuration of the electrophoresis line needs to be personalized and customized. The introduction of intelligent electrophoresis and spray painting production lines has significantly improved the surface coating rate and paint film quality of leaf spring products, and enhanced their anti-corrosion performance. Tailored electrophoretic coating production lines have become an industry trend to address the problem of coating dead corners in complex structures of components.

在環(huán)保與可持續(xù)發(fā)展方面，水性電泳漆的市場(chǎng)份額較2020年增長(zhǎng)23個(gè)百分點(diǎn)。粉末電泳漆使新能源汽車電池包生產(chǎn)效率提升40%。電泳涂裝過程中涂料利用率高，廢液和廢氣排放少。新能源汽車與汽車零部件企業(yè)正通過更精準(zhǔn)、更高效、更環(huán)保的電泳涂裝解決方案提升產(chǎn)品競(jìng)爭(zhēng)力。從“溶劑型”到“水性化”，電泳線正在用綠色技術(shù)重新定義金屬涂裝的未來。

In terms of environmental protection and sustainable development, the market share of water-based electrophoretic paint has increased by 23 percentage points compared to 2020. Powder electrophoretic paint increases the production efficiency of new energy vehicle battery packs by 40%. During the electrophoretic coating process, the utilization rate of the coating is high, and the discharge of waste liquid and exhaust gas is low. New energy vehicle and automotive parts companies are enhancing their product competitiveness through more precise, efficient, and environmentally friendly electrophoretic coating solutions. From solvent based to water-based, electrophoretic lines are redefining the future of metal coating with green technology.
