PMMA Drying Energy Consumption
Fenómeno do problema
PMMA drying takes a long time and consumes a lot of energy
Análise das causas
The low-temperature long-time drying route accumulates large energy consumption; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry literature and should be confirmed first during troubleshooting
Solução
Maintain low temperature and long time for optical parts; ordinary parts can use 90℃×4 hours; heat recovery on dryers; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability
Conclusão principal
Drying routes optimize energy consumption by grading according to quality level; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
