In paper industry, CMC used in the pulping process, can improve the presence rate, increased wet strength; for surface sizing, pigment as excipients to improve internal bond strength, reduced dust printing, printing quality; with in paper coating, and is conducive to the flow of the pigment dispersion, enhancing the smoothness of paper, smoothness, printability, and optical properties. Generally recommended dosage 0.3-1.5%. In the paper industry and a wide range of practical value as an additive, mainly in the water-soluble film-forming polymer and oil resistance.
● surface sizing , the paper has a high density, good resistance to ink permeability, and high smoothness of the wax sets.
● improve the paper cellulose viscous state, thereby enhancing the strength and folding paper.
● The color of the paper and the paper process, CMC help control paste fluidity and good ink absorption
Package:25kg paper bags with liner inside.
