CMC is a high-efficiency papermaking additive. It is mainly used in the preparation of coated paper coatings in the papermaking industry. It can be used as a wet-end additive and surface sizing agent. It has good water retention, dispersibility and excellent shear. Thinning.
1. Application of "Linguang" CMC in coated paper
Control and adjust the rheology of the paint and the dispersibility of the pigment, increase the solid content of the paint; enhance the water retention of the paint, prevent the migration of the adhesive in the paint, improve the leveling of the paint, improve the quality of the coating, and prolong the service life of the scraper ;
It has good film-forming properties and improves the gloss of the coating;
Improve the retention rate of whitening agent in paint and improve the whiteness of paper;
Make the coating pseudoplastic and increase the coating speed;
Give the paint good stability and maintain the uniformity of the paint system.
2. Application of "Linguang" CMC as wet end additive
Improve refining efficiency, promote fiber refinement, and shorten beating time;
Adjust the internal potential of the pulp, disperse the fibers, improve the performance of the paper machine, facilitate the forming of the paper sheet, and improve the evenness of the paper;
Increase the bonding force between fibers and improve the physical strength of paper;
Improve the retention rate of various additives, fillers and fine fibers;
Protect the internal sizing agents such as rosin and AKD, and enhance the sizing effect.
3. Application of "Linguang" CMC in surface sizing
Has good rheology and film-forming properties, increases paper stiffness and smoothness;
Greatly increase the napping speed of paper products and improve the ink absorption performance of paper;
Reduce the pores on the paper surface and improve the oil resistance of the paper;
Improves surface strength, breathability, controls frizz.
