ABS hydrolysis resistance
Fenómeno del problema
[Problem phenomenon] Performance retention of ABS in long-term use in hot and humid environments is questionable
Análisis de la causa
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
Solución
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
Conclusión clave
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
