ABS black speck thermal decomposition
Problembeschreibung
ABS black speck thermal decomposition, melt over 280℃ or residence time too long, temperature management.
Ursachenanalyse
ABS black speck thermal decomposition; melt temperature over 280℃; residence time too long; screw wear; incomplete machine purging; material degradation.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Lösung
①Melt temperature ≤280℃; ②shorten residence time; ③screw inspection; ④purging standards; ⑤degradation monitoring.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
Temperature and residence are the main causes of ABS black speck; equipment and purging are both important; monitoring prevents degradation.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
