  • Factors Affecting the Viscosity Production of HPMC

    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...

  • HPMC classification and dissolution method

    1.Classification: HPMC can be divided into instant type and hot-melt type. Instant-type products disperse quickly in cold water and disappear into the water. At this time, the liquid has no viscosity, because HPMC is only dispersed in water and has no real dissolution. After about 2 minutes, the ...
