| description | Un método para incrementar la concentración de una solución madre de CMC, que comprende: disolver una CMC y una sal alcalina en agua para obtener una solución alcalina de CMC, y opcionalmente modificar el pH de la solución alcalina de CMC a un pH de aproximadamente 7,5 a aproximadamente 11, en donde la CMC tiene un grado de sustitución menor que aproximadamente 0,9, y en donde la solución alcalina de CMC comprende CMC en una concentración mayor que aproximadamente 9,8% en peso, tiene un pH de aproximadamente 7,5 a aproximadamente 11, y tiene una viscosidad menor que aproximadamente 5.000 mPa.
Embodiments of the present description provide methods for increasing the concentration of carboxymethylcellulose alkali solutions that are particularly suitable for use in a high solids paper coating, barrier materials, etc. Generally described, the method includes dissolving carboxymethylcellulose (CMC) and an alkali salt in water to obtain an alkali solution of CMC. The CMC desirably has a degree of substitution less than about 0.9. The alkali solution of CMC includes CMC in a concentration greater than about 9.8% by weight, has a pH from about 7.5 to about 11, and is characterized as having a viscosity of less than about 5,000 mPa. |
