Table 1: Typical Coating Flow Rates
| Line Speed (m/min) | Strip Width (mm) | Film Thickness 1 μm | Film Thickness 2 μm | Application |
|---|---|---|---|---|
| 600 | 1200 | 0.48 L/min | 0.96 L/min | Thin oil film |
| 1000 | 1800 | 1.08 L/min | 2.16 L/min | Protective coating |
| 1500 | 2200 | 1.99 L/min | 3.98 L/min | Conversion coat assist |
| 1800 | 3000 | 3.24 L/min | 6.48 L/min | High-speed lines |
Table 2: Nozzle Selection Guide
| Nozzle Type | Spray Pattern | Best For | Notes |
|---|---|---|---|
| Flat Fan | Uniform sheet | Wide coverage, low-viscosity oils | Ideal for RPO and water-based sealers |
| Hydraulic Fine Spray | Atomized mist | Thin film coatings | High transfer efficiency, low waste |
| Air-Assisted | Ultra-fine mist | Viscous coatings, adhesives | Adjustable droplet size |
| Solid Stream | Narrow jet | Targeted lubrication spots | Minimal overspray |
Table 3: Typical Process Parameters
| Parameter | Range | Impact |
|---|---|---|
| Operating Pressure | 1 – 6 bar | Higher = finer atomization |
| Film Thickness | 1 – 10 μm | Depends on chemistry & end use |
| Line Speeds | 60 – 300 m/min | Requires flow adjustment |
| Viscosity Range | 1 – 150 cP | Determines nozzle/atomization |
