ASA residence time control
Problem Phenomenon
ASA residence time too long degrades, avoid above 280°C, short residence principle.
Cause Analysis
ASA avoids long residence above 280°C; residence time medium with short target; high temperature degradation; cycle management; shutdown handling; purging specifications.; During on-site investigation, verify item by item according to this mechanism, avoid blindly adjusting the machine based on experience alone
Solution
①Avoid long residence above 280°C; ②cycle optimization short residence; ③shutdown cooling; ④purging specifications; ⑤degradation monitoring.; After adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
ASA residence time 280°C red line and short residence are degradation defenses; cycle and shutdown management equally emphasized.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
