Application of the CMC Carboxymethyl Cellulose in Paper Industry

1. The CMC carboxymethyl cellulose for coated paper coatings

In the preparation of coated paper coatings, CMC carboxymethyl cellulose (CMC) can effectively increase the water retention value of the coating, avoid the transfer of soluble adhesives to the paper, thereby improving the leveling of the coating and improving the quality of the coating. Because CMC carboxymethyl cellulose is a good adhesive, it has very good adhesion. One part of CMC can replace 3 to 4 parts of modified starch or 2 to 3 parts of starch-based food compounds, and it can also reduce the amount of latex used, which is beneficial to increase the solid content of the coating film. It can moisturize and promote membrane separation when walking, and it has good demulsification properties, which can make the paper coating have a good gloss and prevent the "orange peel" phenomenon.

2. The CMC carboxymethyl cellulose is used as an adhesive for paper surface

By adjusting the surface of the paper with the adhesive, the tensile strength and smoothness of the paper can be improved, and the compressive strength and air permeability of the paper can be improved as well. It can operate roll-up reasonably, and obtain good packaging and printing suitability. Adding a certain proportion of CMC carboxymethyl cellulose to the surface adhesive can obtain an excellent sealing effect on the surface, and when combined with printing ink, it can improve the quality of color printing pictures and save printing ink. The CMC carboxymethyl cellulose solution mentioned above has good demulsibility. Therefore, adding CMC to the surface sizing agent is beneficial to the demulsification of the paper surface, thereby improving the actual effect of adhesive on the surface.

3. The CMC carboxymethyl cellulose for pulp

Adding CMC carboxymethyl cellulose to the pulp can effectively improve the efficiency of ore crushing, promote chemical fiber optimization, and reduce time jitter; At the same time, CMC carboxymethyl cellulose can evenly disperse chemical fibers, increase the degree of adhesion between chemical fibers, and improve chemical properties of paper. Used in conjunction with the wet zone compressive strength agent, CMC carboxymethyl cellulose can also improve the wet zone compressive strength of paper.
