1. Viscosity Control High-viscosity hydroxypropyl methylcellulose cannot produce very high cellulose only by vacuuming and replacing with nitrogen. However, if a trace oxygen measuring instrument can be installed in the kettle, the production of viscosity can be controlled artificially. 2. Use of...Read more »
