 Hydroxypropyl methylcellulose dissolution

Mixing method:

Mix HPMC powder thoroughly with various other powdered chemical seasonings, and then dissolve it in water. At this point, HPMC can be dissolved without the need for agglomeration. Because there is only a small amount of HPMC powder in every corner, it will dissolve immediately when it comes into contact with water.

All models and specifications can be approved?

Add dry mixing method to the raw materials; When it is necessary to add the solution immediately at room temperature, it is best to use a cold water dispersion type, which can thicken after 10-90 minutes; General models and specifications are mixed and dispersed with hot water, and can be dissolved after cooling with cold water; When dissolved, if there are clumps and encapsulation, it is due to insufficient mixing or adding cold water immediately for general models and specifications, and quick mixing is necessary.

If bubbles are generated during the dissolution process, they can be resolved by?

● Let it stand for 2-12 hours (the specific time is determined by the consistency of the aqueous solution mortar), vacuum packaging, pressure and other methods to remove it, An appropriate amount of defoaming additives can also be added.

● All models and specifications can be fed using dry mixing method;

● It must be immediately added to the solution at room temperature, preferably using a cold water dispersion method. After addition, the actual thickening effect can be achieved within 10-90 minutes;

● After adding cold water dispersion, the general model specifications are first mixed and dispersed with hot water, and can be dissolved after cooling;

● If clumping or encapsulation occurs during dissolution, it should be mixed and dispersed with hot water, and then mixed with cold water. After cooling, it can be dissolved If bubbles appear during dissolution, vacuum packaging can be used, and an appropriate amount of defoamer can be added after dissolution.
