Paper coating

CMC is added to the pulp to improve the pulping efficiency, refine the fibers, adjust the potential in the pulp, evenly disperse the fibers, improve the papermaking performance,Improve the retention rate of fine fibers and physical properties of the finished paper.In coating and sizing, it has excellent water retention, rheology, film-forming and pseudoplasticity. Adjust the solid content of the coating, improve the lubricity of the
oating, reaealize high-speed coating and extend the life of the scraper. the migration of water-soluble adhesive, make the molecules of adsorbed and non adsorbed CMc entangle,
form a network structure in the product, improve the smoothness, strength, wear resistance
of pulp, improve the glossiness of coating, ink absorption and prevent ink permeabilit
