Hpmc 200000 cps is swelling and dispersing in hot water above 85 ℃, which is usually dissolved by the following methods:
1) Take 1 / 5-1 / 3 of the total water demand of HPMC for tile active hot water, stir it with HPMC for tile active to make it completely swelling, and then add the remaining water, which can be cold water or even ice water. In a word, it can be completely dissolved by controlling the stirring temperature (10 ℃).
2) Dry mixing: in case of other powder, HPMC for tile active should be fully mixed with powder, and then added with water, it can be dissolved quickly without agglomeration.
3) Organic solvent wetting method: first disperse Hpmc 200000 cps into organic solvent or wet it with organic solvent, then add it into cold water or add cold water to dissolve it well. Ethanol, ethylene glycol, etc. can be selected as organic solvent.
4) Cold water instant solution method: put an appropriate amount of tap water into the container, and gradually add Hpmc 200000 cps under slow stirring. At the beginning, Hpmc 200000 cps quickly diffuses into the water, but the diffusion does not dissolve. After standing for a few minutes, Hpmc 200000 cps slowly dissolves and the viscosity slowly rises to achieve the effect.
