AI Technical Summary
Existing TAC membrane preparation processes suffer from problems such as the precipitation of small molecule additives during the drying process, leading to issues like precipitation strips and channels on the membrane surface, scratches on the guide shaft, and increased operational intensity, which affect product yield and appearance.
During the TAC membrane drying process, vapors of volatile inhibitors such as water and C2-C10 alcohols are introduced. Their concentration and temperature are controlled by online addition, optimizing the combination of cellulose, plasticizer, and UV absorber, promoting hydrogen bonding, and reducing solvent precipitation.
It effectively reduces dot and strip precipitation of TAC membrane, extends the guide shaft cleaning cycle, improves production efficiency and yield, and is suitable for industrial production.
