Equipment Description:

1. Process flow diagram ‌
[Workpiece loading] → [Degreasing/water washing] → [Phosphating] → [Pure water washing] → [Electrophoresis tank] → [UF water washing] → [Drying and curing] → [Finished product unloading]
‌Key parameters of electrophoretic deposition‌:

Voltage: 150-350V (adjusted according to the shape of the workpiece)

Time: 2-5min (film thickness 15-35μm)

Tannel liquid temperature: 28-32℃ (±0.5℃ control)

2. Technical advantages comparison ‌
Indicators Traditional spray electrophoresis process (this equipment)

Coating uniformity Large manual differences Full surface coverage without dead corners

Corner coverage ≤70% ≥95%

VOC emissions 80-120mg/m³ ＜5mg/m³

Material utilization rate 60-75% 95-98%
‌III. Selection and maintenance recommendations‌
‌Capacity matching‌: Small line (<5m³ tank): 200-500 pieces per day
Large line (>10m³ tank): 2000-5000 pieces per day
‌Maintenance focus‌: Monthly detection of anode membrane permeability (standard value <15%)
Replacement of ultrafiltration membrane chemical cleaning agent (nitric acid + surfactant) every quarter
Calibration of electrode potential sensor every year
Note: Safety requirements‌
Anti-leakage fences must be set up around the tank (insulation resistance >100MΩ)
LEL concentration monitoring must be installed at the exhaust outlet (explosion lower limit warning value <25%)
Emergency power supply must ensure continuous operation of the circulation system for ≥30min
Adopting modular design, it supports integration with AGV logistics system or MES production management system (PROFINET interface reserved).
