The powder coating booth is the core component of the electrostatic powder coating system; its aerodynamic design maintains stable internal airflow, keeping the powder concentration below the lower explosive limit (10 g/m³) to ensure operational safety.
The powder supply center features a 32-channel powder distributor supporting the simultaneous operation of 24 spray guns, with a supply precision of ±1.5 g/min. The fluidized bed utilizes a microporous ceramic plate structure, reducing compressed air consumption by 40% and achieving 98% powder fluidization uniformity. Equipped with a pulse-jet cleaning system, it reduces manual cleaning time by 92% during color changes.
The recovery system employs two-stage separation technology:
A primary cyclone separator utilizes a dual-vortex airflow to recover 85% of the coarse powder.
A secondary cartridge unit captures the remaining 15% of fine powder with a filtration precision of 0.1 μm; a differential pressure sensing system automatically triggers the cleaning cycle when cartridge resistance exceeds 1200 Pa.
