Sodium Carboxymethyl Cellulose (CMC) for Papermaking

Sodium Carboxymethyl Cellulose (CMC) for Papermaking

Sodium carboxymethyl cellulose (CMC) is a natural anionic polymer for use in the pulp and paper industry to help increase paper quality characteristics, acting effectively to satisfy specific roles as follows.

Paper Coating Improving Used to control and modify the rheology of paper coating and the dispersion of pigment, increasing the solids content of coating; Provide coating with pseudoplastic behavior, speeding up the coating process; Improve the water retention of coating, delivering superior control of water-soluble binder migration;
Excellent film forming ability helps improve coating gloss; Promote the performance of the whitening agent in the coating, improving the whiteness of the coated paper; Enhance the lubrication effect of coating, improving the coating quality while extending the service life of scraper blade; Pulp Strength Enhancing Add grinding efficiency of paper pulp, enabling pulp fibers to be refined while shortening pulping cycle; Make pulp fibers uniformly dispersed, improving paper machine runnability and resulting in better paper formation; Increase the retention rate of various additives, fillers and fibers; Increase bond strength between fibers, providing paper products with better physical strength properties; Work together with dry and wet strengthening agents to improve dry and wet strength of paper; Used as pulping sizing agent as gum rosin, AKD and other protective colloids, delivering better sizing effect; Surface Sizing Offer excellent rheology, leading to good film formation; Reduce the airborne porosity on paper surface, providing good resistance to oil and grease; Increase the gloss of paper; Improve paper sheet stability and surface smoothness, while preventing curling; Provide additional paper surface strength and abrasion resistance, reducing paper linting and dusting so that to improve printability and enhance the printing results; Specifications
