Electrophoretic paint, formed through the directional deposition of charged ions under an electric field, creates a coating that, after high-temperature baking, exhibits exceptional adhesion, making it difficult to remove using ordinary paint strippers. Consequently, electrophoretic paint strippers have been developed specifically for剥离 such resilient coatings. This article delves into the working principles and applications of electrophoretic paint strippers.

　　The basic components of electrophoretic paint strippers typically include alkaline substances like potassium hydroxide, along with various auxiliaries. These ingredients, under the influence of an electric field or through chemical reactions, can decompose the molecular structure of electrophoretic paint, causing it to detach from the workpiece surface. The working principle of electrophoretic paint strippers primarily relies on electrophoretic principles and chemical reactions.

　　During the electrophoretic process, the stripper liquid is injected into the interior of the paint film from the anode. Due to the electrophoretic effect, the active ingredients in the stripper can move directionally and penetrate deep into the paint film. Once inside, these ingredients begin to chemically react with the electrophoretic paint, decomposing its molecular structure. This decomposition weakens the paint film's adhesion, ultimately causing it to detach from the workpiece surface.

　　The advantages of electrophoretic paint strippers lie in their effective stripping performance, rapid speed, and thorough cleaning results. Especially for parts with thicker paint films, electrophoretic paint strippers can quickly penetrate and decompose the film, significantly enhancing stripping efficiency. Furthermore, the post-treatment of electrophoretic paint strippers is relatively convenient, reducing the complexity and time cost of manual operations.

　　In practical applications, electrophoretic paint strippers are widely used in industries such as automobile manufacturing, shipbuilding, and aerospace. In automobile manufacturing, electrophoretic paint strippers can quickly and thoroughly remove residues and paint from the body surface and other components, ensuring the vehicle's exterior quality and coating quality. In shipbuilding and aerospace manufacturing, electrophoretic paint strippers同样 demonstrate powerful removal capabilities and efficient cleaning effects, enhancing the corrosion resistance and service life of ship hulls and aircraft surfaces.

　　It's worth noting that electrophoretic paint strippers can be classified into acidic and alkaline types based on their composition and pH values. Acidic electrophoretic paint strippers offer fast stripping speeds at room temperature but may corrode stainless steel substrates and cause color differences after treatment. Therefore, for workpieces with high color change requirements, acidic electrophoretic paint strippers may not be suitable. In contrast, alkaline electrophoretic paint strippers have broader applicability, usable from room temperature to 90°C. Additionally, alkaline electrophoretic paint strippers are typically formulated with a blend of potent organic penetrants, activators, solvents, and water, without harmful substances like dichloromethane. Their volatility and toxicity are relatively low, making them more environmentally friendly.

　　In summary, electrophoretic paint strippers, through a combination of electrophoretic principles and chemical reactions, can efficiently and thoroughly remove electrophoretic paint coatings. Their widespread application fields and significant stripping effects make them indispensable tools in industrial manufacturing. With continuous technological advancements and increasing environmental protection requirements, the performance and application scope of electrophoretic paint strippers will continue to expand and improve.
