Sodium carboxymethyl cellulose (CMC) has a wide range of applications in the papermaking industry. It can be used as an additive in papermaking pulp, a component of paper coating agents, a coating on the surface of the paper, and a reinforcing agent in the pulp.
As an additive in papermaking pulp, CMC can increase the viscosity and fluidity of the pulp, thereby increasing the production efficiency of the papermaking machine. At the same time, it can also be used as one of the components of the paper coating agent to increase the strength and smoothness of the paper, making the quality of the paper more excellent. In addition, CMC can also be used as a coating on the surface of the paper, to play the role of waterproof, oil-proof and increased gloss, and to increase the service life and aesthetics of the paper.
In practical applications, the addition amount and use method of CMC need to be adjusted according to different paper varieties and process conditions to achieve the best results. At the same time, in order to ensure the stability and purity of CMC, strict quality control and testing are required.
