Solubility of CMC
CMC is a natural hydrophilic material, which swells fast in water. Lumps may be formed after material is dispersed into water, To speed up its dissolution, four methods are recommended, as follows:
Method 1, Direct addition
Slowly add the CMC into the water while stirring.
Method 2, Heating
The dissolution rate of CMC molecules depends on temperature. When heating is possible a suitable(and recommended)temperature to prepare a CMC solution is at about 35-50°C.
Method 3, Dry blending
When it is used with other raw materials, it is better to mix the solid together first,and then dissolve them.
Method 4, Dispersion in a water miscible organic solvents
CMC may be dispersed in glycerin, ethanol, or propylene glycol at first and the water is the added to slurry.
