TPU Color Masterbatch Dispersion
문제 현상
After TPU coloring, color streaks and color difference appear, and the compatibility between color masterbatch and base material is poor
원인 분석
TPU color masterbatch needs pre-drying; insufficient compatibility between the masterbatch carrier and TPU causes poor dispersion; low processing temperature and insufficient plasticization aggravate color streaks; when troubleshooting on site, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
해결 방법
①Premix color masterbatch with TPU and dry them together; ②select TPU-carrier color masterbatch pellets; ③ensure sufficient plasticization at processing temperature; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
For TPU coloring, dry first then disperse; premixing and drying plus TPU carrier can prevent color streaks and color difference; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
