CMC for Papermaking
CMC for Papermaking
CMC is a highly efficient papermaking auxiliaries. It is mainly used in the preparation of coated paper coatings in the paper industry. It can be used as a wet-end additive, surface sizing agent, etc. It has good water retention, dispersibility and excellent shearing. Thinning.
1. Application of “Linguang” CMC in coated paper
Control and adjust the rheology of the coating and the dispersibility of the pigment, improve the solid content of the coating; enhance the water retention of the coating, prevent the migration of the adhesive in the coating, improve the flatness of the coating, improve the coating quality, and prolong the service life of the scraper ;
Has good film forming properties and improves the gloss of the coating;
Improve the retention rate of whitening agent in the coating and improve the whiteness of the paper;
Making the coating pseudoplastic and increasing the coating speed;
Provides good stability to the coating and maintains the uniformity of the coating system.
2. Application of “Linguang” CMC as a wet end additive
Improve the refining efficiency, promote fiber refinement, and shorten the beating time;
Adjusting the internal potential of the slurry, dispersing the fiber, improving the papermaking performance of the paper machine, facilitating the formation of the paper sheet and improving the uniformity of the paper;
Increase the bonding force between fibers and increase the physical strength of paper;
Improve the retention of various additives, fillers and fine fibers;
Protect the sizing agent such as rosin and AKD to enhance the sizing effect.
3. Application of “Linguang” CMC in surface sizing
Has good rheology and film formation, increasing paper stiffness and smoothness;
Greatly improve the pulling speed of paper products and improve the ink absorption performance of paper;
Reduce the paper pores and improve the oil resistance of the paper;
Improve surface strength, air permeability, and control curl.
