ABAK chemical resistance
Problembeschreibung
ABAK chemical resistance is better than pure ABS but inferior to pure PA; solvent contact should be evaluated.
Ursachenanalyse
PA provides solvent and oil resistance; ABS has average chemical resistance; the alloy chemical resistance is between the two; the ratio has an influence; specific media still need verification.; During on-site investigation, verify item by item according to this mechanism, avoiding blindly adjusting the machine based solely on experience
Lösung
①Evaluate according to the medium type; ②a high PA ratio improves chemical resistance; ③conduct compatibility tests; ④manage the use environment.; After adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
ABAK chemical resistance is a function of the ratio; the PA proportion is the main variable; testing verifies specific media.; After confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
