ABS hydrolysis resistance
Problembeschreibung
[Problem phenomenon] Performance retention of ABS in long-term use in hot and humid environments is questionable
Ursachenanalyse
ABS has good hydrolysis resistance (nitrile structure), performance retention in hot and humid environments is better than PC; long-term hot water still needs verification; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Lösung
Hot and humid parts can use ABS with aging verification; long-term hot water verifies performance retention; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Wichtigste Erkenntnis
ABS hydrolysis resistance is above average, hot and humid parts rest assured after verification; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
