What role does carboxymethyl cellulose sodium CMC play in the papermaking process?

The art of papermaking has been passed down for a long time, and all kinds of materials are used in it. Sodium carboxymethyl cellulose (CMC) has great functions in the papermaking process. CMC has the ability to thicken. In the pulping stage of papermaking, the viscosity of the pulp suspension can be moderately increased. Just like a spoon stirred in the soup, the soup is thick and uniform because of it. The pulp suspension is thickened, and the fiber distribution is more uniform, so that it does not settle in one place. In this way, the texture of the paper produced is uniform, there is no risk of uneven thickness, and the strength of the paper must be guaranteed. If the thin paper can withstand a certain tension without cracking, the thick paper can also maintain a tight structure. It has the effect of dispersion. It can evenly disperse many components in the pulp, such as fibers, fillers and additives. It is like stars scattered in the night sky, each in its place, and not coalescing with each other. In this way, the filler can be evenly filled in the fiber gap, and the smoothness and printability of the paper are improved. When printing, the ink can be evenly attached, and the pattern and text are clearly presented, so as not to be blurred and smudged. In addition, CMC has the power of retaining water. In the wet part of the papermaking, it can prevent the rapid loss of moisture, just like holding up a "water umbrella" for the pulp fibers. The fibers must be fully hydrated and moisturized, and the flexibility is enhanced. When the paper is formed, it can be better interwoven into a web, and the physical properties of the paper, such as tensile strength and burst resistance, must be improved. And because the moisture is lost evenly, the paper shrinks evenly during the drying process, and it is not easy to produce wrinkles and warps, and the quality is better. CMC is used in the papermaking process to thicken, disperse and retain water, help produce high-quality paper, and is an indispensable auxiliary for papermaking technology.

How to Store Paper-Grade Sodium Carboxymethyl Cellulose CMC Properly

The proper storage of paper-grade sodium carboxymethyl cellulose (CMC) is quite important. This is a delicate matter, and specific regulations must be followed to ensure its quality. CMC is easy to absorb moisture, so the storage place must be dry. Choose a cool place, away from water vapor, so as not to damp the warehouse and cause it to deteriorate. If it is immersed in water, the properties of CMC will change greatly, and its efficacy will also be damaged. Temperature is also the key. Avoid hot topics to prevent its chemical structure from being affected. Extremely hot places may cause CMC to decompose and reduce performance. It is advisable to choose a cool place with moderate temperature to keep CMC safely. Furthermore, the packaging needs to be tight. Use the sealed device to block the intrusion of outside air and moisture. If the package is damaged, the CMC is easy to react with external substances and affect the quality. During storage, be careful not to mix with other things. Different chemicals, sundries, or react with CMC, damage its purity. And do a good job of insect prevention and rodent prevention. Bugs and rats bite the package, which not only damages its appearance, but also causes pollution and endangers the quality of CMC. Daily inspection is also indispensable. Check regularly to see if the package is damaged or shows any signs of moisture. If there is any abnormality, dispose of it quickly to avoid greater losses. In this way, it is necessary to properly store paper-grade carboxymethyl cellulose sodium to make its performance stable and ready for emergencies.

How to Use Carboxymethyl Cellulose Sodium CMC with Other Papermaking Auxiliaries

The method of papermaking is very delicate. The preparation and use of sodium carboxymethyl cellulose (CMC) and other papermaking aids are related to the advantages and disadvantages of paper products, which cannot be ignored. Sodium carboxymethyl cellulose has good bonding properties and can increase the polymerization force of pulp. To use it, first take an appropriate amount of CMC and dissolve it in warm water. The water temperature should be moderate, about 50 to 60 degrees Celsius. Stir it slowly to make the CMC gradually melt into a uniform glue. This glue is quite viscous and can be added slowly during pulping. The dosage depends on the type of paper. If making tissue paper, the amount of CMC should be small; if making thick paper or special paper, the amount can be increased as appropriate. As for other papermaking aids, such as sizing agents, it can make paper waterproof and liquid-resistant. When used, it is often combined with CMC. First, the sizing agent is prepared in proportion. After the CMC glue is integrated into the pulp, the sizing agent is slowly injected and stirred evenly. In this way, the water resistance of paper can be greatly improved. Another example is retention aids, which can keep fibers and fillers on the paper and reduce loss. When blending with CMC, CMC should be added first, and then the retention aid should be added after it fully interacts with the pulp. The synergy of the two can ensure that the paper is evenly formed and the quality is stable. Furthermore, defoamers are also commonly used additives in papermaking. When CMC glue or pulp is stirred, it is easy to produce foam, which affects the quality of paper products. At this time, add a defoamer as needed to remove foam and make the papermaking process smooth. All kinds of papermaking additives have their own capabilities. When blending and using, it is necessary to follow the characteristics of the paper and the production process, and be cautious. Make the additives complement each other to produce high-quality paper products, which is of great benefit to the papermaking industry.
