PCABS color masterbatch carrier matching
Fenómeno do problema
【Problem Phenomenon】PC/ABS uses wrong color masterbatch carrier, poor dispersion and color mottling
Análise das causas
The color masterbatch carrier must be compatible with PC/ABS: carrier melting point and processing temperature mismatch causes poor dispersion or degradation; PC-based carriers suit high PC ratio; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
Solução
Select PC/ABS dedicated carrier for color masterbatch; processing temperature matching verification; first article color check to lock the ratio; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
PC/ABS color masterbatch recognizes the carrier, dedicated material prevents color mottling; 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 similar problems later
