LDPE Film Temperature Judgment Skills
Fenómeno del problema
Judge temperature by bubble surface state: rough and hazy means too low, unstable and easy to break means too high.
Análisis de la causa
Melt temperature level directly changes the bubble's appearance and behavior; experienced operators take a smooth and transparent bubble surface as the criterion for suitable temperature.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience.
Solución
①Observe the bubble surface to judge the temperature range; ②Calibrate in combination with measured temperature; ③Approach the optimal temperature step by step; ④Record and verify.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Conclusión clave
Adjusting temperature by watching the bubble is a practical on-site skill; combining sensory judgment with instrument measurement is most reliable.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
