POM small-batch drying
Fenómeno do problema
Drying small amounts of POM samples in the laboratory with an ordinary oven gives unstable results
Análise das causas
Small batches are spread with uneven thickness and the oven humidity is affected by the environment; 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 data and should be confirmed first during troubleshooting
Solução
Small-scale test: vacuum oven at 80°C×2 hours; spreading thickness less than 20mm; record the conditions; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
Standardization of small-scale drying ensures data comparability; after confirming effectiveness, fix 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
