Qingguo Intelligent is a leading China automobile electrophoresis production line manufacturer. The following is an overview of the production process and its application advantages.
1. Pre processing:
-Cleaning and degreasing: Use cleaning agents to remove oil and dirt from the surface of the vehicle.
-Rust removal: Remove surface rust by sandblasting or chemical methods.
-Phosphating: Treating metal surfaces into phosphate compounds to improve coating adhesion and corrosion resistance.
2. Electrophoretic coating:
-Electrophoretic tank: Immerse the pre treated vehicle body into an electrophoretic coating tank, which is filled with an aqueous solution containing paint.
-Applying voltage: Applying voltage through a power source causes positively charged paint particles to move towards the vehicle body (negative electrode) and deposit, forming a uniform coating.
3. Water washing:
-After electrophoresis, rinse the coated parts with clean water to remove excess paint and chemicals, ensuring the quality of the coating.
4. Drying and curing:
-Drying the coating to accelerate the curing process is usually achieved through hot air or infrared heating equipment.
5. Post processing (optional):
-Perform subsequent treatment on the electrophoretic coating, such as applying varnish, to further improve its appearance and protective performance.
-Coating type: Water based coatings are usually used, including resins, pigments, and additives.
-Film thickness: Electrophoretic coating can effectively control the coating thickness, generally within the range of 10-20 microns.
-Temperature and time: The temperature and time during the electrophoresis process need to be adjusted according to the characteristics of the coating and the body material to ensure optimal coating performance.
1. Excellent corrosion resistance: Electrophoretic coating can evenly cover complex shaped components, greatly improving corrosion resistance and extending service life.
2. Environmental friendliness: Electrophoretic coating mainly uses water-based coatings to reduce the emission of harmful substances and meet environmental requirements.
3. High efficiency: The automotive electrophoresis production line can quickly process large quantities of products and is suitable for assembly line production.
4. Material saving: Electrophoretic coating can effectively reduce the waste of coatings, as it can be recycled after layer by layer coating.
5. Coating uniformity: Whether it is a complex structure or a large plane, electrophoretic coating can ensure the uniformity and consistency of the coating.
6. Strong adhesion: The chemical properties of electrophoretic coatings provide strong adhesion between the coating and the substrate, effectively resisting peeling and detachment.
The comprehensive advantages of the automobile electrophoresis production line make it widely used in modern automobile manufacturing and an important process means to improve the quality and durability of automobiles.
