production lines
I. Items that must be checked before operation
Ventilation system: VOC concentration ≤50mg/m³ (verified by handheld detector)
Electrostatic device: ground resistance <10Ω, distance between spray gun and workpiece 20-30cm
Emergency stop function: all equipment will be powered off within 3 seconds after triggering
II. Personal protection standards
Anti-static clothing (surface resistance 10⁶-10⁹Ω) + goggles + chemical protective gloves
Respiratory protection: NIOSH N95/P100 filter cotton, replaced every 4 hours
III. Equipment startup process
Start the ventilation system first, and test the air quality after running for 5 minutes
Run the equipment without load for 10 minutes to confirm that there is no abnormal vibration or abnormal sound
When the automatic line is started, the operator evacuates to the safety yellow line (≥2 meters)
IV. Key points for daily inspection
Spray gun atomization effect: particle size 50-150μm (clean the nozzle when abnormal)
Conveyor chain lubrication: friction coefficient <0.15 (add food-grade grease)
Exhaust gas treatment pressure difference: 500 -1000Pa (clean the filter bag if the limit is exceeded)
Ground continuity: resistance <2Ω (tighten the terminal)
V. Emergency treatment plan
Paint leakage: start emergency exhaust, transfer the leaked material with explosion-proof pump, and cover the residue with sand and soil
Fire: Use Class D fire extinguisher first, cut off non-fire power supply, and keep emergency lighting
VI. Maintenance cycle recommendations
Daily: clean the spray room filter cotton and check the conveyor belt alignment
Weekly: calibrate the coating thickness detector (error ±2μm)
Monthly: test the insulation resistance of the explosion-proof motor (≥1MΩ)
