HPMC dissolution method

All models can be added to the material by dry blending. When it needs to be added directly to the aqueous solution at room temperature, it is best to use a cold water dispersion type, and it usually takes 10-90 minutes to thicken after adding. For ordinary models, stir and disperse with hot water first, then add cold water, stir and cool to dissolve. If there is agglomeration and wrapping during dissolution, it is because the stirring is not sufficient or the ordinary model is directly added to the cold water. At this time, it should be stirred quickly. If bubbles are generated during dissolution, it can be left for 2-12 hours (the specific time is determined by the consistency of the solution) or removed by vacuuming, pressurizing, etc., or adding an appropriate amount of defoaming agent.
