The application of electrophoresis technology (electrophoretic coating) in doors and windows offers significant advantages, particularly in terms of corrosion resistance, эстэтыка, and production efficiency.
- Superior Corrosion Resistance
Longlasting Protection: The electrophoretic coating forms a uniform and dense protective layer on metal surfaces (such as aluminum alloy or steel), even penetrating fine gaps, significantly enhancing resistance to salt spray, acid rain, and humid environments, thereby extending the service life of doors and windows.
Ideal for Outdoor Use: Particularly suitable for coastal or highly polluted areas, reducing rust and oxidation issues.
- Excellent Adhesion and Uniformity
Complete Coverage: Through the electrodeposition process, the coating evenly adheres to complex shapes and edges (Нап., grooves, weld points), avoiding missed spots common in traditional spraying.
Strong Bonding: The coating adheres firmly to the metal substrate, preventing peeling or blistering.
- EcoFriendly and Efficient
Low VOC Emissions: Electrophoretic coatings are waterbased, with minimal volatile organic compounds (VOCs), complying with environmental regulations (Нап., EU RoHS standards).
High Material Utilization: Coating utilization can exceed 95%, far surpassing traditional spraying (3060%), reducing waste.
Treatable Wastewater: Waste liquid can be recycled through sedimentation and filtration, minimizing environmental impact.
- Aesthetic and Versatile Finishes
Smooth Surface: The coating provides excellent leveling, resulting in a smooth finish free from orange peel or grit.
Wide Color Options: Customizable matte, glossy, or metallic finishes, with common choices including black, белы, and woodgrain effects.
Longlasting Color: Superior UV resistance compared to conventional spray coatings, preventing fading or chalking.
- CostEffectiveness and Productivity
Automated Production: Suitable for largescale continuous production, reducing labor costs and increasing efficiency by 35 times compared to manual spraying.
Reduced PostProcessing: A single electrophoresis coating can replace both primer and topcoat, simplifying the production process.
- Бяспека і даўгавечнасць
Flame Retardant: Electrophoretic coatings exhibit good heat resistance, enhancing fire safety.
Scratch and Wear Resistance: Hardness typically exceeds 3H (pencil hardness), making it suitable for hightraffic door and window components.
Application Considerations
Material Limitations: Primarily used for conductive metals (Нап., алюміній, steel); nonconductive materials require pretreatment.
High Initial Investment: Equipment and bath solutions are costly, making it more suitable for largescale production.
Slow Color Switching: Changing colors requires thorough tank cleaning, reducing flexibility.
Выснова
Electrophoresis technology is particularly wellsuited for midtohighend doors and windows (Нап., навясныя сцены, villa doors/windows) that demand durability and environmental friendliness, significantly reducing maintenance costs and enhancing product value. For smallbatch or custom orders, a costbenefit analysis is recommended.
