Considerations: Follow manufacturer's recommendations for optimal distance
2. Cooling System Parameters
Definition: Settings for air or water cooling systems
Significance: Controls lamp and substrate Nhiệt độ
Adjustment:
- Adjust airflow or water flow rate
- Monitor cooling system performance
- Ensure adequate cooling for lamp longevity
Considerations: Proper cooling extends lamp lifespan and prevents overheating
3. Reflector Configuration
Definition: The design and alignment of UV reflectors
Significance: Affects UV distribution and Cường độ
Adjustment:

Example: 200 mW/cm² × 5 seconds = 1000 mJ/cm²
2. Exposure Time Calculation
Formula: Exposure Time (seconds) = Curing Zone Length (cm) / Conveyor Speed (cm/second)
Example: 100 cm curing zone ÷ 20 cm/second = 5 seconds exposure
3. Production Rate Calculation
Formula: Production Rate (Đơn vịs/hour) = (Conveyor Speed (cm/minute) × 60 minutes) / Đơn vị Length (cm)
Example: (200 cm/minute × 60) ÷ 10 cm/Đơn vị = 1200 Đơn vịs/hour
