Spray Painting and Baking Equipment for Large Buses and Heavy-Duty Vehicles

I. Core Design Parameters

Dimensional Requirements

• Minimum dimensions recommended: Length ≥15m × Width ≥6m × Height ≥4.5m (to accommodate double-decker buses or extended trucks).

• Modular design: Expandable structure for future extensions (e.g., additional workstations or increased height).

Structural Materials

• Framework: Galvanized steel structure for corrosion resistance and dynamic load capacity.

• Walls/roof: Double-layer insulated color steel panels (rock wool core) for thermal insulation and noise reduction.

• Flooring: Anti-static epoxy flooring with anti-slip texture to prevent paint mist accumulation.

II. Key Equipment Selection

Spray System

• Dust-free environment: Three-stage filtration (primary + intermediate + high-efficiency filters, ≥98% efficiency).

• Spray equipment: High-pressure airless spray guns (flow rate ≥20L/min) with adjustable nozzles for large-area coverage.

• Lighting: Explosion-proof LED strips (illuminance ≥800 Lux) to ensure uniform coating.

Curing Oven System

• Energy options:

  • Gas heating: ≥85% thermal efficiency, ideal for continuous operation.

  • Electric heating: Lower upfront cost but higher operational expenses (dependent on local electricity rates).

• Temperature control: PID-regulated ±2°C accuracy, curing temperatures adjustable between 60–80°C based on paint specifications.

Ventilation System

• Airflow calculation: ≥100 air exchanges per hour (e.g., 150,000 m³/h for a 30m×10m×5m space).

• Energy-saving design: Heat recovery devices (e.g., heat exchangers) reduce energy consumption by ≥30%.

III. Safety & Environmental Compliance

Safety Measures

• Explosion-proof design: ATEX/IECEx-certified electrical equipment and ventilation motors.

• Fire protection: Automatic sprinklers + combustible gas detectors linked to emergency exhaust.

• Emergency protocols: Emergency stop buttons and escape routes (width ≥1.2m).

Environmental Requirements

• Waste gas treatment:VOC removal: Activated carbon adsorption + RCO catalytic combustion (≥90% efficiency).

• Particulate filtration: Wet scrubbers or bag dust collectors.

• Noise control: Soundproofing for equipment (≤75 dB(A)).
