Unsatisfactory toughening effect of modified cellulose acetate butyrate
Problembeschreibung
Unsatisfactory toughening effect of modified cellulose acetate butyrate, impact strength improvement below the expected target
Ursachenanalyse
Insufficient toughener addition or uneven dispersion
Poor compatibility between toughener and matrix, weak interfacial bonding
Improper processing temperature (deviating from 170-230°C), toughener degradation or poor dispersion
Insufficient mixing, toughener agglomeration
Toughener particle size mismatch
Lösung
Increase toughener addition to a reasonable ratio
Select toughener with good compatibility with cellulose acetate butyrate
Reasonably set processing temperature within the 170-230°C range
Strengthen mixing to ensure uniform dispersion
Select toughener with suitable particle size
Wichtigste Erkenntnis
Toughening effect needs to be addressed from addition amount, compatibility and dispersion
