Insufficient Dissolution in CMC Solution Preparation
Fenómeno do problema
Undissolved particles in CMC solution preparation
Análise das causas
CMC is poured directly into water, forming a surface gel layer that hinders internal dissolution; stirring speed is insufficient
Solução
1)Pre-disperse CMC in a small amount of hot water first, then add to a large amount of water; 2)Increase stirring speed to 500rpm; 3)Extend dissolution time to 2h
Conclusão principal
CMC dissolution needs pre-dispersion and full stirring to prevent surface gel coating
