Product Description

Automatic ED painting line/ electro-coating line for automotive parts

Electrophoretic deposition (ED), is a term for a broad range of industrial processes which includes electrocoating, e-coating, cathodic electrodeposition, anodic electrodeposition, and electrophoretic coating, or electrophoretic painting. A characteristic feature of this process is that colloidal particles suspended in a liquid medium migrate under the influence of an electric field (electrophoresis) and are deposited onto an electrode. All colloidal particles that can be used to form stable suspensions and that can carry a charge can be used in electrophoretic deposition. This includes materials such as polymers, pigments, dyes, ceramics and metals.
 
The process is useful for applying materials to any electrically conductive surface. The materials which are being deposited are the major determining factor in the actual processing conditions and equipment which may be used.

Technical advantages:
1. Non-poisonous
2. Easy automatic control
3. Water solubility

Operating principle:
Putting the workpieces and corresponding electrode into the water-soluble paint and connecting the electricity supply. The resin and fillers in the paint will separate out equably on the surfaces of the workpieces and deposit to form water-fast paint films on the physical and chemical effects of electric fields.

Main parts of the full line:
1. Pretreatment device
2. Electrophoretic tank system
3. Electrophoretic transferring tank system
4. Stirring apparatus
5. Filter system
6. Water washing system
7. Ultrafiltration system
