Paper-making Grade CMC

Compared with traditional powdery CMC, the granular CMC produced by Hondo Chemical is more convenient to operate in the papermaking industry, and has better dissolution performance and higher production efficiency. The granular form of CMC greatly reduces the problem of dust flying and improves the operating environment. Granular CMC has excellent fluidity, which reduces manual operation and improves the level of factory automation and production efficiency. Granular CMC has a slow dispersion speed in water, avoiding local agglomeration and caking, making the dissolution process of sodium CMC more uniform and stable. Granular CMC is suitable for multiple process links such as wet-end addition, surface sizing, and coating, and can be flexibly selected according to different paper types and performance requirements.

As an anionic dispersant, paper making grade CMC increases the negative charge on the surface of fibers and fillers, promoting their uniform distribution in the pulp and reducing sedimentation. Paper making grade CMC enhances fiber bonding and filler dispersion, improving tensile strength, burst strength, and folding endurance-important for high-strength papers and packaging grades.This effectively improves the smoothness and gloss of the paper. Adding the granule CMC in the wet-end process of papermaking can significantly enhance the bonding force between fibers, greatly improving the tensile strength, bursting strength, and flexibility of the paper. This makes the paper more durable and capable of bearing heavier loads, meeting the application requirements for high-strength paper products.

As an efficient dispersant and suspending agent, Cellulose CMC optimizes the rheology of the pulp system, improve the stability of the papermaking process and the uniformity of the paper sheets. Adding paper making grade CMC cellulose can reduce pores on the paper surface, improves the ink absorption performance, and strengthens the adsorption capacity for ink. This ensures the clarity and consistency of printed text and images while reducing paper breakage during the printing process. Meanwhile, CMC gum effectively enhances the smoothness and gloss of the paper, making the surface more delicate and aesthetically pleasing. It is particularly suitable for high-quality paper products with strict surface requirements, such as coated paper and copy paper.

Hondo CMC exhibits excellent dispersing properties in the papermaking process, effectively preventing fiber agglomeration and ensuring uniform pulp distribution, thus improving the forming consistency of the paper. Additionally, carboxymethyl cellulose CMC has excellent water-holding capacity, which reducing water loss during papermaking process and reducing energy consumption for pulp concentration and drying, thereby enhancing overall production efficiency. It also can improve the retention rate of fillers, reduces filler waste, and decreases the usage of other chemical additives, helping to control costs and enhance environmental friendliness.

The hydrophobic-hydrophilic balanced structure of CMC can adjust the water absorption rate of paper, making the paper more suitable for different printing or packaging needs.The paper making grade CMC controls the penetration of printing inks, improves printing clarity, printability, smoothness and glossiness, enhances the uniformity of ink absorption, and reduces ink seepage. Sodium CMC as a coating binder or thickener, significantly improves the adhesiveness and uniformity of the coating, improves paper evenness, helps form a tighter and denser paper structure, and improves the binding force of the coating layer to prevent powdering and delamination.
