Powder charging efficiency ≥85%, Faraday effect suppression technology
3, ‌ safety enhancement ‌ powder concentration monitoring +CO₂ automatic fire extinguishing (Ex ia IIB T4 explosion-proof certification) grounding resistance ≤1Ω, electrostatic leakage rate > 0.1mJ/ms
According to the requirements of GB 6514-202X Painting Operation Safety Regulations: ‌ space matching ‌ : cross-sectional area of dusting chamber ≥ 1.5 times of workpiece projection area, ‌ production capacity calculation ‌ : backward linear speed according to curing furnace volume ×0.7 (loading factor)
‌ Environmental compliance ‌ : Configure RTO incineration or activated carbon adsorption.

Main structure and components:

Workpiece feeding → degreasing (waste water treatment) → washing → passivation (waste water treatment) → drying → electrostatic powder spraying (powder recovery) → curing → cooling → quality inspection.
Key parts technical details ‌‌ electrostatic spray gun ‌‌ rotary cup ‌ : 60-100kV high pressure, suitable for complex surfaces (such as aluminum alloy wheels) ‌ friction ‌ : no corona discharge design, reduce the risk of aluminum powder explosion ‌ intelligent feedback ‌ : Real-time monitoring powder charging efficiency (≥82%) ‌ passivation tank ‌ Chromium-free passivation solution (zirconium-titanium system), pH 4.0-4.8, temperature 35-40℃
Film thickness 0.3-0.8μm, salt spray test ≥500h (ASTM B117) ‌ curing furnace ‌ zone temperature control: preheating area (150±5℃) → curing area (200±3℃) → cooling area Hot air circulation fan: 304 stainless steel, wind speed 0.5-1.2m/s adjustable ‌ suspension conveyor chain ‌ double chain redundancy design, tensile strength ≥5000N insulation hook surface resistance ≥1×10¹³Ω, to prevent electrostatic breakdown coating.
