The process is divided into anode electrophoresis and cathode electrophoresis. If the coating particles are negatively charged and the workpiece is an anode, the coating particles are deposited into a film on the workpiece under the action of electric field force, which is called anode electrophoresis. Conversely, if the paint particles are positively charged, the workpiece is a cathode, and the coating particles are deposited on the workpiece into a film called cathode electrophoresis. The general process of anodic electrophoresis is: pre-treatment of the workpiece (oil removal → hot water washing → rust removal → cold water washing → phosphating → hot water washing → passivation) → anodic electrophoresis → post-treatment of the workpiece (clean washing → drying). 1. Remove oil. The solution is generally a hot alkaline chemical degreasing liquid, the temperature is 60℃ (steam heating), and the time is about 20min. 2. Wash with hot water. Temperature 60℃ (steam heating), time 2min. 3. Remove rust. With H2SO4 or HCl, such as with hydrochloric acid rust removal solution, HCl total acidity ≥43 points; Free acidity >41 pwen; Ajoute 1.5% ajan netwayaj; Lave nan tanperati chanm pou 10 ~ 20min. 4. Lave nan dlo frèt. Dlo ak dlo frèt pou 1 min. 5. Fosfatasyon. Avèk fosfatasyon tanperati mwayen (fosfat 10min nan 60 degre), solisyon an fosfatasyon ka pwodwi fini ki disponib nan komès. Pwosesis ki anwo a ka ranplase tou pa sablaj → lave. 6. pasivasyon. Sèvi ak dwòg yo ki matche ak solisyon fosfatasyon an (founi pa manifakti a ki vann solisyon fosfatasyon an) nan tanperati chanm pou 1 a 2min. 7, elektwoforèz anod. Konpozisyon elektwolit: H08-1 penti elektwoforetik nwa, fraksyon solid 9% ~ 12%, fraksyon mas dlo distile 88% ~ 91%. Voltage: (70±10) V; Tan: 2 ~ 2.5min; Tanperati penti abazde: 15 ~ 35 degre; Penti PH: 8 ~ 8.5. Remake byen ke inlet pyès la ak plas priz yo ta dwe koupe. Nan pwosesis la nan elektwoforèz, aktyèl la pral piti piti diminye ak epesman nan fim nan penti abazde. 8. Dlo pwòp. Lave nan dlo frèt k ap koule. 9. Sèk. Li ka kwit nan fou a nan (165±5) degre pou 40 ~ 60 minit.
