HPMC powder and a large number of other powdery material ingredients, mixing fully with a blender, and then adding water to dissolve, HPMC can dissolve at this time, without agglomeration, because each small corner, only a little bit of HPMC powder, water will dissolve immediately. - Putty powder and mortar production enterprises are using this method.

Hot water solution method: Because HPMC is not dissolved in hot water, so the initial HPMC can be evenly dispersed in hot water, and then quickly dissolved when cooling, two typical methods are described as follows:
1) Put the required amount of hot water in the container and heat it to about 70℃. Under the slow stirring gradually add hydroxypropyl methyl cellulose, HPMC began to float on the surface of the water, and then gradually form a slurry, the slurry is cooled under the stirring.
2), add 1/3 or 2/3 of the required amount of water in the container, and heat to 70℃, according to the method of 1), disperse HPMC, prepare hot water slurry; Then add the remaining amount of cold water to the hot slurry, stirring and cooling the mixture.
Powder mixing method: HPMC powder and a large number of other powdery material ingredients, mixing fully with a blender, and then adding water to dissolve, HPMC can dissolve at this time, without agglomeration, because each small corner, only a little bit of HPMC powder, water will dissolve immediately. - Putty powder and mortar production enterprises are using this method.
