Insufficient Dissolution in CMC Solution Preparation
Problem Phenomenon
Undissolved particles in CMC solution preparation
Cause Analysis
CMC is poured directly into water, forming a surface gel layer that hinders internal dissolution; stirring speed is insufficient
Solution
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
Key Takeaway
CMC dissolution needs pre-dispersion and full stirring to prevent surface gel coating
