Unstable Viscosity of CMC Solution Preparation

문제 현상

Viscosity of CMC solution preparation fluctuates ±30%, exceeding ±10%

원인 분석

CMC molecular weight distribution is uneven with batch differences; solution preparation temperature fluctuates; stirring is insufficient

해결 방법

1)Select CMC with narrow molecular weight distribution; 2)Constant solution preparation temperature ±1°C; 3)Stir fully for 30min to ensure uniformity

핵심 요약

CMC viscosity stability is determined by molecular weight distribution and solution preparation conditions
