Description of Paper-Making Grade CMC
Sodium CMC papergrade has excellent adhesion, thickening, flocculation, film, colloids protection, retain moisture, chemical stability and excellent performance of pulp fiber affinity.
Sodium carboxymethyl cellulose applying in coating size can well control and adjust the rheological and dispersing properties, raise the solid content, and increase water retention and lubricating effects of coatings.
Sodium carboxymethyl cellulose Improves the quality of coatings and prolongs the operation life of slicker. It makes finished paper with good brightness and ink absorption effect. Promote better fiber refinement process and Shorten pulping time.
Sodium carboxymethyl cellulose adjusts electric potential in the pulp. Disperse fiber. It improves the production capacity of the paper machine. During size on the surface of the paper, it can reduce the blowholes of paper and increase the grease-proof effect. CMC can improve brightness surface tension, sizing force, the strength of stiffness and smoothness of paper. Reduce surface picking and raise the printing quality.
