KimaCell® CMC PM100 sodium carboxymethyl cellulose is made of pulp or fine cotton, in a kneader, using ethanol as a medium, using sodium hydroxide, chloroacetic acid (or sodium chloroacetic acid) through alkalization and ether woody reaction, and then neutralized, washed, The finished product is obtained by centrifuging alcohol, drying, crushing, testing, mixing and packaging. CMC is a colloid that can be dissolved in both cold and hot water. Its aqueous solution has extremely high transparency and fluidity, and can form a stable network structure at different temperatures. It is not only a strong dispersant and binder, but also a water-retaining agent that acts as an emulsifier. Because of these excellent and specific properties, CMC has attracted the attention of the majority of papermakers and has been widely used in the production of paper and cardboard.

Application of CMC PM100

KimaCell® CMC PM100 sodium carboxymethyl celluloseOnly because the aqueous solution of CMC has anti-enzymolysis properties and inert metabolism, the paint has good stability, and its specific performance is to maintain the uniformity of the paint, so that the paint is not easy to deteriorate and rot during the storage period. Second, CMC is used as the surface sizing of pulp, and the paper can be finished by surface sizing to increase stiffness, smoothness, and enhance its surface hardness and air permeability. Can effectively control bending and obtain good printability. Adding a certain proportion of CMC to the surface sizing can make the surface get a good seal, and the facing with the printing can improve the definition of color printing and save ink. The aqueous solution of CMC has very good film-forming properties, so putting CMC in the surface sizing agent will help the sizing agent to form a film on the surface of the paper, thus improving the effect of surface sizing.
