Hardening system for cellulose mass - uses eddy mixing vessel with controlled oxygen feed to dissolve into the mass

摘要

The system to harden a cellulose mass, using oxygen under alkali conditions, uses an eddy mixing vessel with the cellulose suspension satd. with 2-8% of oxygen. The system gives a cheap, simple and easily-supervised process, without requiring further treatment such as peroxide finishing, giving shorter reaction times with small pumps for the necessary pressures.
