ABAK flowability management
문제 현상
ABAK flowability is better than pure PA but is affected by the compatibilizer; as compatibilizer increases, flowability decreases.
원인 분석
In the ABS-g-MAH compatibilized PA/ABS blend system, melt flowability decreases as compatibilizer dosage increases; the compatibilizer improves the interface but increases viscosity; flowability and mechanical properties need to be balanced; select high-flow grades.
해결 방법
①Optimize compatibilizer dosage without excess; ②select high-flow grades; ③appropriately increase the processing temperature; ④compensate with runner and gate design.; After adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
ABAK flowability and compatibility trade off against each other; optimized compatibilizer dosage is the key; grades and processes compensate for flowability.; After confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
